Animals commonly called reptiles, amphibians, birds, and mammals are all tetrapods-a term that means "four feet". The transition from water to land is fascinating to scientists in part because it is our history-the transition documents the evolution of tetrapods and humans are tetrapods. Tetrapods form a clade. Which of the following is true for tetrapods

Animals commonly called reptiles, amphibians, birds, and mammals are all tetrapods-a term that means "four feet".

Explanation: Tetrapods are a group of vertebrates that namely;

1. amphibians

2. reptiles

3. birds

4. mammals.

Tetrapods are made up of all living land vertebrates, and some vertebrates who once lived on land. Such vertebrates have adapted to live in seas and oceans Examples of such vertebrates are

1. whales

2. dolphins

3. seals

4. sea turtles and many more

One of the key features of tetrapods is that they have four limbs or, their ancestors had four limbs. Are known as tetrapods

both anaerobic and aerobic respiration use glucose (or other carbohydrates), proteins and lipids to produce atp and nadh. cell uses those energy molecules, obtained from food and   breaks them down during the chemical reactions of respiration. in anaerobic respiration, nadh is regenerated to nad+ by enzymes lactate dehydrogenase (lactate is produced, e.g. in muscle cells) or by alcohol dehydrogenase where ethanol is produced (alcohol fermentation), while in aerobic respiration, electrons from nadh are deposited in the mitochondria to regenerate nad+ (electron transport chain. anaerobic respiration produces 2 atp per molecule of glucose compared to aerobic respiration where about 38 atp molecules are produced.
