Tadpole Vs Frog

There are several major trends that developed in the vertebrate group that has allowed the transition from aquatic to terrestrial life. Some of these trends are improved respiration, protective body covering, and more efficient ways to reproduce. The adaptations that have allowed the transition from aquatic to terrestrial life are: Jaws, lungs, jointed vertebrate limbs, water tight skin, amniotic egg for reproduction. In birds and mammals another adaptation that has evolved is that they are endothermic meaning they generate internal heat.

This allows us to see, up close, the transformation of animals. What was once isolated to only the sea, evolved into something that could now dwell on land as well. Throughout the course of history, more and more evolutionary traits will occur allowing different species to prosper where they once could not.

Adaptations in terrestrial environments involve the structural and functional qualities of the organism, to achieve the adequate intake of oxygen and other essential substances for the animal to survive, the evolution of more complex anatomical structures were required. Gravity is stronger on land than water, which means terrestrial organisms have to be more structural than aquatic organisms. Also, the balance of gas exchange with water loss is a key feature to survive in land. For example plants, when doing photosynthesis require carbon dioxide and water to produce oxygen, at the end of this process a lot of water is lost and terrestrial plants have to compensate the water being lost and the water taken from soil. Furthermore, the dispersal of gametes by wind or other animals have helped plants reproduce in large amounts and create varieties of species of the same kind. Short-term weather patterns as well as long-term climate conditions based on precipitations, temperature, wind, humidity as well as other factors are survival obstacles that organisms in land have to adapt to live; endothermic organisms have to maintain a constant internal

Biological evolution itself is the change in characteristics of living organisms over generations. Evolutionary theories suggest that all organisms alive today share a common ancestor. As unlikely as it sounds, evidence has been discovered proving this theory (relations from a spider to a monkey).

Some plants and animals have to adapt to the amount of oxygen and visibility underwater. For example, plants have adapted to the amount of sunlight they receive in certain environments, and cattails and water lilies have adapted to be able to survive humid climates. For animals, certain fish like trout have adapted to clear and cool water with a large amount of oxygen. On the other hand, other types of fish, like catfish, are able to survive in an area with a low oxygen level and gloomy visibility. Since otters live on the land surrounding the water, they have adapted to be able to swim to catch their food. Frogs and alligators have adapted to their environment by being able to live on the land after coming from underwater as an egg. Lastly, beavers have adapted to use their teeth to create the dams they live

Vertebrates are known to be animals with backbones. Tooth reduction is one of the major evolutionary trends that developed among major vertebrate groups that allowed for the transition from aquatic to terrestrial life. Evolution of limbs and being able to breath air are other evolutionary trends that took placeThese trends include improved respiration and protective and insulating body coverings. More over the transition from water to land also included changing to more efficient reproductive methods like having a placenta for some animals or egg layers for other animals. Lastly, the morphology of organisms evolved such that for land they would have paired, muscular appendages used for crawling and

Through the concept of evolution, ecology, population, community and the environment. Species through different periods evolve physiologically and adapting to new environments. Animals who can’t live or survive in certain regions either migrate or die. Common ancestors often link to present day organisms showing biologically and different aspects of adaptations.

In Poe’s short stories we can often find characters very similar to Poe himself. One of the most prominent and easiest ones to see is in Poe’s short story “Hop-Frog.” In this story we can see some similarities in the main character Hop-Frog, and Poe himself. Hop-Frog is a court jester who is a dwarf, he and his very dear friend Trippetta, who is also a dwarf, are from a far-off foreign land. Trippetta was very beautiful and fulfilled many duties for the king; such as planning masquerades. Hop-Frog is a dwarf that has something wrong with his legs, to where he cannot move and walk as other men do; however, he has an extraordinary amount of upper body strength. Hop-Frog can climb almost anything with ease. Poe and Hop-Frog are not alike in this respects, but they are alike in the sense of their alcohol intake. Poe was never able to drink alcohol, even one sip of alcohol would make Poe so delirious, that he did not know what was going on (Edgar Allan Poe). The same is very much true for Hop-Frog.

There are five general long-term trends of evolution. Which is ubiquity, diversity, specialization, complexity, and

Examples of evolution and adaptation are present in every organism on Earth. Organisms adapt and change according to their surroundings. As their surroundings change, they change, or they die. These are the basic concepts of evolution. Organisms will adapt to survive and thrive, or they will die out. The species alive today as a result have evolved and have undergone much change from their ancestors. Invertebrate species are just some examples of this in action, but if one was to look at the specific species of invertebrates and analyze their adaptations and traits, the evidence of evolution would be quite surprising. An astounding example of this in action is a little insect known as the honey bee.

Tadpoles are really cool looking but there faces are so ugly. Tadpoles are really small you can't really see them that much they have to grow so to see them.The tadpoles have big eyes there eyes help them to see. Tadpoles are really not smart when there young but when they get a little order there smart. People use tadpoles for fishing. Alot of animals eat tadpoles like snakes, fish, and other things.When the mother gives birth to the frog the mother lives and goes somewhere alse.Then the mother comes back and lies more .

Three of these adaptations are its skin and its hind legs. Its skin allows it to breathe on land as well as in water, also, it helps the frog camouflage from its surroundings. Its hind legs are very powerful and the feet are webbed. The frog’s skin is very moist and thin allowing oxygen to diffuse through it. Oxygen can pass through via both water and air. The skin is filled with millions of tiny capillaries which transfer the diffused oxygen into the bloodstream. The skin is what helps the frog breathe when it hibernates. Its skin also has the ability to change color and blend into its surroundings. Tiny pigments in the cells can change to all shades of green and brown disguising the frog from predators. The frog can also hide under water because of the locations of its eyes, ears, and nose. The skin is a major adaptation for the frog. The strong hind legs of the frog allow it to jump and swim at high speeds. Frogs are widely known for their hopping abilities. The two feet of the frog are webbed, allowing it to get more resistance pushing into the water when it extends its legs. The webbing is in between its toes so that it can close and open it when needed. The frog has many bodily systems that work together, two of them are the respiratory and circulatory systems. The respiratory system obtains oxygen and disposes of excess carbon dioxide and water. The respiratory system then adds the oxygen to the blood which

Compare / Contrast the evolution of Aquatic Organism to Terrestrial Organism. -what did fish evolve from? What were the different stages of their evolution?

One example of convergent evolution is the body structure of the shark and the dolphin. Even though they are not related they look alike, and move through the ocean similar. But a shark is a fish and a dolphin is a mammal, but they live in similar environments and needed to adapt in order to survive.

Frogs, toads, caecilians, and salamanders are the members of the class Amphibian (amphi- meaning “on both sides” and bios- meaning “life”). These members always require water for reproduction. Most Amphibians undergo metamorphosis, which is a usually degenerative pathological change in the structure of a particular body tissue. And, in the case of Amphibians, it is the changing of a tadpole into
