Frogs Essays - Amphibians, Frog, Chorus Frogs, Pickerel Frog Frogs A Frog is a small, tail less animal that has bulging eyes. Almost all frogs have long back legs. The strong hind legs make the frog able to leap farther than the length of its body. Frogs live on every continent except Antarctica, but tropical regions have the greatest number of species. Frogs are classified as amphibians. Most amphibians, including most frogs, spend part of their life as a water animal and part as a land animal. Frogs are related to toads, but are different from them in a few ways. The giant frog of west-central Africa ranks as the largest frog. It measures nearly a foot (30 centimeters) long. The smallest species grow only 1/2 inch (1.3 centimeters) long. Frogs also differ in color. Most kinds are green or brown, but some have colorful markings. Although different species may vary in size or color, almost all frogs have the same basic body structure. They have large hind legs, short front legs, and a flat head and body with no neck. Adult frogs have no tail, though one North American species has a short, tail like structure. Most frogs have a sticky tongue attached to the front part of the mouth. They can rapidly flip out the tongue to capture prey. Frogs have such internal organs as a heart, liver, lungs, and kidneys. Some of the internal organs differ from those of higher animals. A frog's heart has three chambers instead of four. And although adult frogs breathe by means of lungs, they also breathe through their skin. The eggs of different species vary in size, color, and shape. A jelly like substance covers frog eggs, providing a protective coating. This jelly also differs from species to species. Some species of frogs lay several thousand eggs at a time. But only a few of these eggs develop into adult frogs. Ducks, fish, insects, and other water creatures eat many of the eggs. Even if the eggs hatch, the tadpoles also face the danger of being eaten by larger water animals. The pond or stream in which the eggs were laid sometimes dries up. As a result, the tadpoles die. Certain tropical frogs lay their eggs in rain water that collects among the leaves of plants or in holes in trees. Other tropical species attach their eggs to the underside of leaves that grow over water. When the eggs hatch, the tadpoles fall into the water. Among some species, one of the parents carries the eggs until they hatch. For example, the female of certain South American tree frogs carries the eggs on her back. Among another species of frog, the midwife toad, the male carries the eggs wound around his hind legs. Males of another species, Darwin's frog, carry the eggs in their vocal pouch. Some tropical frogs lay their eggs on land. They lay them under logs or dead leaves. These frogs have no tadpole stage. A young frog hatches from the egg and begins life as a land animal. Tadpoles are not completely developed when they hatch. At first, the tadpole clings to some support in the water, using its mouth or a tiny sucker. A tadpole has no neck, and so its head and body look like one round form. The animal has a long tail and resembles a little fish. It breathes by means of gills, which are hidden by a covering of skin. A tadpole's form changes as the animal grows. The tail becomes larger and makes it possible for the animal to swim about to obtain food. Tadpoles eat plants and decaying animal matter. Some tadpoles eat frog eggs and other tadpoles. In time, the tadpole begins to grow legs. The hind legs appear first. Then the lungs begin to develop and the front legs appear. The digestive system changes, enabling the frog that develops to eat live animals. Just before its change into a frog, the tadpole loses its gills. Finally, a tiny frog, still bearing a stump of a tail, comes up from the water. Eventually, the animal absorbs its tail and assumes its adult form. After a frog becomes an adult, it may take a few months to a few years before

How to Adjust Standard Book Review Formats to Nonfiction Entries

How to Adjust Standard Book Review Formats to Nonfiction Entries How to Adjust Standard Book Review Formats to Nonfiction Entries It sometimes seems that writing a book review is a piece of cake. That’s because you often mix it up with a book report which is just a record of events that happened in a certain literary work. Students usually get such an assignment in secondary or high schools maximum (because the task doesn’t require a great deal of analysis or critical thinking). But it’s not the same with book reviews which are common homework at colleges and universities. You’ll have to make some efforts in order to comply with the regular academic standards and live up to your professor’s expectations, especially when you need to adapt book review formats to nonfiction entries. But don’t get rattled – we’ve compiled a list of guidelines on this topic that will help you to do your best while completing this assignment. Review the Author’s Previous Works and Interests Make sure you understand the style of the writer and can follow his/her thread of thoughts. In novels or poems, there is usually a story, but a scientific work or news article can be devoid of the obvious plot, and it may be hard for you to perceive the main idea. So, read about author’s background and have a perfunctory look at his/her previous works. Carefully Consider the Audience While reviewing a fiction story, it’s easy to imagine who the readers are. But when it comes, let’s say, to social sciences, you can’t predict who is interested in the subject. That’s why the target audience in your head has to be pretty wide – if you want to have a more specific image, go to such websites like Amazon and read reviews on the work you are going to describe. There, you’ll certainly gain some useful insights. Do the Research for the Evaluation While writing a book review on a nonfiction work, you need to have some solid knowledge about the subject matter it deals with. Otherwise, you won’t be able to assess the statements of the author and provide any kind of analytical evaluation in your assignment. And this is the most important part of nonfiction book reviews. Dwell upon the Importance of the Topic Does the writer cover some burning issues or creates useless articles on pasta types that already have been described dozens of times? Be sure that you estimate the importance of the subject matter and hit it over the fence for your audience. Don’t Play with Over- or Underestimation Your professor wants to see an adequate review with constructive criticism or worthy praise. Don’t say that someone’s arguments are not reliable enough just to fill in the space in your writing assignment. Include only your real assumptions without any exaggerations. This way, your book review will be authentic and original. Writing a nonfiction book review is complicated exactly because it is easy – every supervisor expects that you will be able to do it, so they want to see something more than just following the standard set of regulations. Consider out tips and create a paper that stands out from the crowd. All in all, you can easily buy book review online from our agency.
