Frogs vs. Toads

When you see a creature hopping a farseeing the side of the creek, bathroom you tell if its a frog frog or a toad? Many people rear end non tell the difference amidst the two. They ar similar in many ways. When flavor at the two, there are some differences in them. For instance the frog and toad both have bulging eye; however, the frogs eyes are s illuminely bigger than the toads. As you read on you will learn the differences and similarities between the frog and toad. There are 2000 known species of the frog compared to the 300 kinds of toads. A frog is a small, slim, four legged amphibian with smooth skin and foresighted powerful hind legs with webbed feet. The biggest frog is the Giant frog, sometimes called Goliath Frog, in West Africa. This Giant frog laughingstock grow up to a foot in length. The frog is green or brown skinned with dark markings, pointed head, long hind legs, and can get one to four inches in length. Some frogs have suckers on their feet which help them cling to tree diagram trunks as they climb, known as tree frogs. The toad on the other hand has dry, warty skin with non as powerful hind legs. Toads are also lucubrate compared to the slim frog. The toad will puff up with conduct at times. Toads walk slow and have shorter legs than the frog.
Toads are light brown skinned with brown markings; dry skin, flabby and can get up to three inches in length. The frog belongs to the family Ranidae family while the toad belongs to the Bufonide family. Frogs and toads are both amphibians and are cool blooded. The two are carnivores and are found almost anywhere. A frog however, is not found in Antarctica; the toad is not found in Australasia, Polar Regions, Madagascar, and Polynesia. You are most apparent looking at a frog if you are approximately water or in water. If youre walking…...

Tadpoles and Toads by Fleur Adcock

...‘Tadpoles’ and ‘Toads’ are two fascinating, descriptive poems written by Fleur Adcock, about her love for toads and frogs. As the titles suggest, ‘Tadpoles’ refers to the birth of several frogs, and ‘Toad’ describes the death of an adult frog. In both poems, there is clear evidence of Adcock’s emotional connectino with the creatures. Adcock draws a personal element by connecting the young tadpoles with her grandson, Oliver. Looking at the tadpoles now, she is reminded of her grandson, when he was ‘[still] a tadpole in Elizabeth’s womb’. Although Oliver is ‘too far away now for [me] to call him across the world’, Adcock makes it clear that she deeply misses him, and wishes he were by her side to witness the growth of these little tadpoles. ‘Toads’ is a different poem, where Adcock mourns the death of her beloved pet toad. However, towards the end of the poem, there is a sense of reincarnation where the toad chooses to turn up to the narrator’s doorstep. The fact that the toad seems to reappear again to them, ‘a little shadow shaped like a brown leaf hoppedout of greener leaves and came to me’ in stanza seven, suggests that the toad may have come in her father’s spirit, suggesting a very personal and spiritual connection. ‘Greener leaves’ highlights the rebirth of the animal and earlier in stanza three, Adcock states that she ‘saw his spirit in every visiting creature’. Perhaps ‘Toads’ is about her appreciation for animals and a sense of belief in reincarnation. Similarly, in......

...Reyes, Charles Jourdan F. January 14, 2013 V BS Biology Bi183.1 Section A Exercise 1: Baseline Data Results Figure 1. Force (N), ECG (mV) and heart rate (bpm) of the pithed frog. Figure 2. Force (N) per unit time (s) of the pithed frog. Figure 3. ECG (mV) per unit time (s) of the pithed frog. Table 1. Time between QRS and the start of ventricular contraction(s). 1. Observe the heart and describe its behavior. Is this behavior consistent with what is shown in the data above? Yes. The heart of the frog rhythmically contracts and relaxes. This behavior is supported by the general fluctuations observed force values and the consistent patterns of the ECG occurring in regular intervals. 2. Explain the basis for the delay between the atrial and ventricular contractions. The said delay is mainly caused by the A-V node and its adjacent conductive fibers, causing an overall delay of 0.13 second (Guyton and Hall 2006). Conduction in the transitional, nodal, and A-V bundles is dampened by the decreasing number of gap junctions along the pathway of conduction, creating great resistance against the conduction of excitatory ions from one fiber to another. This ensures that the atria completely empty blood into the ventricles before ventricular contraction occurs. 3. Describe the relationship between the ECG QRS complex and the beginning of ventricular contraction. What is the physiological significance of this relationship? ...

The Frog Prince

...The Frog Prince One fine evening a young princess put on her bonnet and clogs, and went out to take a walk by herself in a wood; and when she came to a cool spring of water with a rose in the middle of it, she sat herself down to rest a while. Now she had a golden ball in her hand, which was her favourite plaything; and she was always tossing it up into the air, and catching it again as it fell.       After a time she threw it up so high that she missed catching it as it fell; and the ball bounded away, and rolled along on the ground, until at last it fell down into the spring. The princess looked into the spring after her ball, but it was very deep, so deep that she could not see the bottom of it. She began to cry, and said, 'Alas! if I could only get my ball again, I would give all my fine clothes and jewels, and everything that I have in the world.'       Whilst she was speaking, a frog put its head out of the water, and said, 'Princess, why do you weep so bitterly?'       'Alas!' said she, 'what can you do for me, you nasty frog? My golden ball has fallen into the spring.'       The frog said, 'I do not want your pearls, and jewels, and fine clothes; but if you will love me, and let me live with you and eat from off your golden plate, and sleep on your bed, I will bring you your ball again.'       'What nonsense,' thought the princess, 'this silly frog is talking! He can never even get out of the spring to visit me, though he may be able to get my ball for me, and...

Cane Toads

...WHAT EFFECTS ARE CANE TOADS PRODUCING TOWARDS THE SUSTAINABILTY OF ECOSYSTEMS AND THE SURVIVAL OF NATIVE SPECIES Chelcy Jordan SUST 1000 October 10 2012 The introduction of invasive species can often lead to unpredictable alterations and a shift within natural ecosystems. Cane toads were originally introduced to Australia in 1935. They were brought into Australia to prey on specific pests that were attacking sugar cane plants. Cane toads are highly adaptive and can easily adjust to climate changes and feeding grounds. The growth of reproduction in cane toads has formed a species invasion on the habitat of native animals. Immense competition and a shift in ecosystems are a result of their significant growth rate. What effects are cane toads producing towards the sustainability of ecosystems and the survival of native species? Many animals, and plant species have been either finding new ways to adjust to changes caused by the introduction of cane toads. Cane toads have impacted natural ecosystems so drastically that they have left a strenuous effect on native species ability to maintain their own survival. This is crucial when looking at the effects cane toads have on sustaining plant and animal life within ecosystems. Dramatic changes in an ecosystem could potentially fail due to inadequate nutrients and energy distribution. It is important to examine ways in which cane toads affect ecosystems so environmentalists can predict potential negative shifts and try to......

...criticism of Disney movies portraying negative stereotypes, violence and unethical for young children content is, however, growing with every new film. Even though Disney is “multinational mass media corporation” and so cannot please everyone, their films are still fairytales that apart from being entertaining, contain didactic messages and, therefore should be held to high critical standards. Disney films are filled with contradicting images and contain dark and childhood shattering moments, which can deeply influence impressionable minds of children. For example in Dumbo and The Princess Frog beautifully drawn characters and nature are opposed to some seriously disturbing images of monsters and demons, like Dumbo’s hallucinations or shadow monsters in The Princess Frog. In Dumbo, the mother elephant is beaten and incarcerated and little Dumbo cannot see her anymore, and in The Princess Frog, the evil Shadow Man, murders a heroic firefly by crushing him up with his foot. Describing the influence of Disney’s films on individual identities, Henry A. Giroux and Donald A. Gross and Todd G.Shields state, that “Disney’s animated films provoke and inform children’s imagination, desires, roles, and dreams while simultaneously sedimenting affect and meaning.”(91) Any good fantasy or a fairly tale contains the forces of good and evil, and inevitably reflect the realities of the world we live in. These and similar films and cartoons leave a heavy sediment in the heart of an adult, who......

Frogs

...Frogs are a diverse and largely carnivorous group of short-bodied, tailless amphibians composing the order Anura (Ancient Greek an-, without + oura, tail). The oldest fossil "proto-frog" appeared in the early Triassic of Madagascar, but molecular clock dating suggests their origins may extend further back to the Permian, 265 million years ago. Frogs are widely distributed, ranging from the tropics to subarctic regions, but the greatest concentration of species diversity is found in tropical rainforests. There are approximately 4,800 recorded species, accounting for over 85% of extant amphibian species. They are also one of the five most diverse vertebrate orders. The body plan of an adult frog is generally characterized by a stout body, protruding eyes, cleft tongue, limbs folded underneath and the absence of a tail. Besides living in fresh water and on dry land, the adults of some species are adapted for living underground or in trees. The skin of the frog is glandular, with secretions ranging from distasteful to toxic. Warty species of frog tend to be called toads but the distinction between frogs and toads is based on informal naming conventions concentrating on the warts rather than taxonomy or evolutionary history; some toads are more closely related to frogs than to other toads. Frogs' skins vary in colour from well-camouflaged dappled brown, grey and green to vivid patterns of bright red or yellow and black to advertise toxicity and warn off predators. Frogs......

Frogs vs Tods

...Frogs vs. Toads Frogs and toads are “small, tailless animal” that belongs to the amphibian class. (Forester 536 & Gibbons 303) Everyone thinks that frogs and toads are different from one another but in fact “there is no clear distinction between” them (Burnie & Wilson 440). Most people find it very difficult to differentiate between a frog and a toad that they often mix them up. Their physical features are very much alike but they are different on the basis of anatomy and habitat. When you see a creature hopping along the side of the creek, can you tell if it’s a frog or a toad? Frogs are very unique because “some frogs have colorful markings” (Forester 536). While as toads are marked in a “drab shades of brown, tan, gray, or black that serves as camouflage” (Campbell 217). Besides their markings, “almost all frogs have the same basic body structure” (Forester 536). Frogs have “long, powerful hind legs, which they use for jumping” (Forester 536). “Frogs can leap long distances, but also use their limbs to swim, burrow, and even to glide from tree to tree” (Wake 337). Unlike frogs, toads “generally have squat bodies and short legs” (Campbell 217). They do not “jump” like frogs so they “make short hops or even walk” (Campbell 217). As opposed to skin, frogs have “thin, moist skin” (Forester 536) and “the skin of most toads is dry, rough, and covered with warts” (Gibbons 303). There is an advantage to a toad’s dry skin. It’s “warty skin allows it to inhabit drier regions than...

Frogs

...tree. On the ground at its feet, something strangely familiar hops by: a frog. Ichthyostega, prehistoric predecessor to the modern frog, lived 370 million years ago during the Devonian Period. Sometimes referred to as "the first four-legged fish," skeletal remains of this earliest-known amphibian were first discovered in East Greenland. Surprised? Few people realize just how ancient frogs are. For 190 million years, the ancestors of modern frogs have roamed (if not ruled) the earth, looking much the same as they do today. The secret to their success is their amazing adaptability. As amphibians, frogs have one webbed foot in each of two worlds. The advantages of this double life are clear to see: Are land predators giving you trouble? Dive into the water. Not enough to eat in the pond? Hop out and see what they're serving on shore. Frogs have evolved to live in an astounding variety of climates. They can be found just about anywhere there's fresh water, from the desert to the Arctic, on all continents except Antarctica. Though they thrive in warm, moist tropical climates, frogs also live in deserts and high on 15,000 foot mountain slopes. The Australian water-holding frog is a desert dweller that can wait up to seven years for rain. It burrows underground and surrounds itself in a transparent cocoon made of its own shed skin.

Frog Dissection

...Then, the Bio Amp cable was attached to the Bio Amp socket on the PowerLab. The three lead wires were attached to the Bio Amp cable. Other materials such as dissecting dish, metal pins, scissors, forceps, strong thread with a barbless hook, acetylcholine solution, epinephrine solution, and Frog Ringer's solutions in cold, warm, and room temperature were collected. The force transducer was zeroed by adjusting the baseline value to zero. A weight between 5 and 50 grams was hanged from the force transducer and was recorded for five seconds to calibrate the force transducer. The N value was calculated and the calibration was implemented. A double-pithed frog was dissected by making a longitudinal and lateral incision along the ventral surface of the abdomen with scissors. The tissue and the sternum was cut away to expose the thoracic cavity. The pericardium was cut away with the forceps to expose the heart. The force transducer was attached to the heart by lifting up the apex of the heart and piercing it with a hook. The tension on the thread was adjusted and the thread was left perpendicular to the table, instead of an angle. The lead wire alligator clips were attached to the pins holding the frog to record the ECG. The red lead was attached to the left forelimb, the black lead was attached to the right forelimb, and the green lead was attached to the right hindlimb. In the first exercise, the baseline heart rate was observed from the force generated during the cardiac......

Frog Heart

...of this phenomenon is the frog heart, which will continue to beat in situ for several hours allowing for the study of basic cardiac functions. The heart is made up of specialized tissue called cardiac muscle. Cardiac muscle is similar to skeletal (striated) muscle, but exhibits some special properties, the most important of which is rhythmicity. Specialized heart muscle cells called pacemakers spontaneously depolarize and repolarize; the depolarization spreads to the entire heart via electrical connections between cardiac muscle cells called gap junctions. This process occurs in rhythmic fashion, giving rise to an intrinsic, regular heartbeat. While no external stimulation is required to maintain the heartbeat, the heart receives continuous input from the sympathetic and parasympathetic nervous systems. Cardiac muscle responds to a variety of neurotransmitters, which can increase or decrease the heart rate. These molecules are able to influence heart rate by changing the rate of spontaneous depolarization of the heart’s “pacemaker” cells, located in the sinoatrial (SA) and atrioventricular (AV) nodes of the mammalian heart. In the frog, the sinus venosus is similar to the SA node.

Anatomy of a Frog

...Summary of the Anatomy of the Frog As in other higher vertebrates, the frog body may be divided into a head, a short neck, and a trunk. The flat head contains the brain, mouth, eyes, ears, and nose. A short, almost rigid neck permits only limited head movement. The stubby trunk forms walls for a single body cavity, the coelom (Anatomy of the Frog). All the frog's internal organs--including the heart, the lungs, and all organs of digestion--are held in this single hollow space (Anatomy of the Frog). The Skeleton and Muscles The frog's body is supported and protected by a bony framework called the skeleton. The skull is flat, except for an expanded area that encases the small brain. Only nine vertebrae make up the frog's backbone, or vertebral column. The human backbone has 24 vertebrae. The frog has no ribs (Anatomy of the Frog). The frog does not have a tail. Only a spike like bone, the urostyle, remains as evidence that primitive frogs probably had tails. The urostyle, or "tail pillar," is a downward extension of the vertebral column (Anatomy of the Frog). The shoulders and front legs of the frog are somewhat similar to man's shoulders and arms. The frog has one "forearm" bone, the radio-ulna. Man has two forearm bones, the radius and the ulna. Both frog and man have one "upper arm" bone, the humerus (Anatomy of the Frog). The hind legs of the frog are highly specialized for leaping. The single "shinbone" is the tibiofibula. Man has two lower leg bones, the......

Boiled Frog

...Running Header: Boiled Frog Boiled Frog “The parable of the boiled frog” is probably one of the most common disabilities. This disability is a gradual evil. According to The Fifth Discipline be Peter M. Senge (2006), this disability gets it name from the obvious, a boiling frog. Senge explains that if you put a frog in boiling hot water, he will react. But if you put him in calm, cool water and gradually turn up the heat the frog will not realize what is happening and by the time the water is boiling, it is to late for the frog to react. (Senge, 2006) In business, this discipline is demonstrated when issues are overlooked or not thoroughly addressed. These issues can slowly grow and start to affect other aspects of the business. Once the business realizes what is happening, the issues have grown, they become very costly to address and in many cases cause the collapse of the business. Another example of this “boiled frog” disability is the economy crisis. In 2004 the economy seemed to be booming but underlying issues existed. These issues were known but not directly addressed. By 2008 the housing market crashed due to overlooked problems. This crash lead to the failure of the financial system and the economy was turned upside down. Today we are still fighting to get out of the “boiling water”. Like the frog, the economy was unaware or indifferent of the dangerous water around it. By the time the water started to boil, we were in too......

Frog Nerve

...follow the “all or none” rule. The “all or none” rule being that if a stimulus is strong enough to depolarize the membrane of the neuron to threshold, then an action potential will be fired. Each stimulus that reaches threshold will produce an action potential that is equal in magnitude to every other action potential for the neuron. Compound action potentials do not exhibit this property since they are a bundle of neurons and have different magnitudes of action potentials. Compound action potentials are also graded, meaning the greater the stimulus, the greater the action potential. 2. Action potentials are said to be all or none responses. Why does the frog sciatic nerve give a graded response? 2. Action potentials are said to be all or none responses. Why does the frog sciatic nerve give a graded response? The frog sciatic nerve gives a graded response de to the nerve being a bundle of axons and not a single axon, resulting in it not showing the “all or none” rule of an axon. In this experiment, if one axon is generating an action potential, then a small nerve impulse will be seen. If all axons are simultaneously generating action potentials, then a large nerve impulse will be seen. This means that the sciatic nerve impulse is graded due to it being able to be none, small, medium, large, or maximal. 3. What was the smallest voltage required to produce the maximum (largest) CAP? What proportion of the nerve fibers were excited to produce this maximal......

Frog Nerve

...Frog Nerve Exercise 1: Action Potential Threshold Using the Horizontal Compression buttons and the scroll bar display the data you wish to include in your report. Study Questions 1. How does a CAP differ from a single action potential? 1. How does a CAP differ from a single action potential? Answer CAP or compound action potential is a measure of the sum of the "all or none" single action potential of a group of fibers in a single nerve. The single action potentials are events that occur when sodium channels are activated causing the depolarization of a neuron. Single Action potentials are considered to be all or none responses, they travel down the length of the axon and then release a neurotransmitter into the synapse. CAPs occur from extracellular stimulation of the nerve. CAPs are considered to be graded meaning the greater the stimulus the greater the magnitude of the CAP because different axons have different excitation thresholds. 2. Action potentials are said to be all or none responses. Why does the frog sciatic nerve give a graded response? 2. Action potentials are said to be all or none responses. Why does the frog sciatic nerve give a graded response? Answer Frog sciatic nerves gives a graded response because of the difference in size of of the axon diameter and the inclusion of several axons rather than just a single axon. A single nerve cell containing an axon will have an all or none response because in order for an action potential......
