You can find them in fish, insect, etc. A selection of animals which live on land have a skin thin enough for gases to pass through. An earthworm's habitat and behavior is influenced by its need for a moist skin. Since they lack lungs, all plethodontids breathe through their skin and the mucous membrane in the mouth and throat; these surfaces must remain moist at all times in order to absorb oxygen. The animal S lives on land and breathes through spiracles and tracheae. Air enters and leaves the tracheal system through the spiracles. • Soft, moist skin • Go through metamorphosis • Lay jelly-like eggs • Most can breathe in water with gills as young, and breathe on land with lungs as adults • old blooded (ectothermic) Characteristics • Warm blooded (endothermic) • Mothers nurse their young • reath through lungs • All have hair at some stage in Paragraphs 4 to 8: There are three main types of amphibians - anura, apoda, and urodela. Explanation: Exchange of gases in earthworms and frogs take place by diffusion through moist body hence their skin appears moist and slimy. The answer is (d) moist and slimy. The Animals breathing through the skin (Skin respiration) Are all those animals that have the ability to perform their respiratory process cutaneously.. Earthworms have dramatically evolved to breathe through their moist skin and so it is very necessary that they keep their skin moist and slimy all the time in order to breathe and exchange the gases. The two organisms which breathe only through their moist skin are Class:11Subject: BIOLOGYChapter: ANIMAL KINGDOMBook:ERRORLESS Board:NEETYou can ask any dou. (a) Which of the animals could be Amoeba . C) It is done to get extinct: done clear. The animal Q can stay in water as well as on land and can breathe both, through moist skin and lungs. Thus, the frog is an animal which can . Animals that breathe with their lungs can come from all over the world and live in many different types of environments, ranging from the highest of mountain tops to the lowest jungles. So breathe through your skin. These animals have hard, scaly skin, and are cold blooded. B: birds are the only group of animals with an outer body covering of feathers. The carbon combines with oxygen to form carbon dioxide (CO2) and is released back into the atmosphere as a waste product when animals breathe and exhale. Tadpoles can also take in oxygen through their skin, a trait that aids in gas exchange (bringing in oxygen and expelling carbon dioxide, as with lung respiration) while the tadpole is living completely underwater. Question 5. J.B. Graham, in Encyclopedia of Fish Physiology, 2011 Skin. 1: Insect respiration: Insects perform respiration via a tracheal system, in which openings called spiracles allow oxygen to pass into the body. their bodies. Carbon dioxide is expelled from the body of the earthworm through its skin. answer choices In insects like cockroaches, breathing takes place through a network of fine tubes called tracheae. When they are on land they breathe through their nostrils and a pair of lungs. (c) Animal P can be a fish as it has gills for breathing. Larval Monopterus respire through extensive subepithelial . They use gills to breathe when they are young, and use lungs to breathe when they are adults. In the youngest animals, with body weight below 100 mg, gas exchange through the skin exceeded that through the lungs . Their skin is thin and allows the exchange of carbon dioxide and oxygen in and out of the body. . Suggest corrections. 40 Votes) Most notable is the presence of gills instead of lungs during this stage. Gills are the respiratory organs for the animals dwelling in water like fishes. In animals like cow, buffalo, dog and cat the respiratory organs and the process of breathing are similar to those in humans. This trait is known as "bimodal breathing," in which an animal uses two different systems for bringing in oxygen. The worm's skin is protected by a thin cuticle and kept moist by a slimy mucus. Amphibians are animal with moist, hairless skin through which water can pass in and out, e.g. (b) Animal Q can be a frog as it lives on land and water and can breathe through both moist skin and lungs. They can live on land and in water. Mammals either breathe through the nose or the mouth.
