Reptiles are better suited to dry land than their amphibian ancestors because
Vaselesa [24]

Answer:

<u><em>All of the above.</em></u>

Explanation:

1. Their watertight skin minimizes moistures loss: <em>Reptiles have a reputation that they are “slimy” when we touch and hold them; however, they have dry skin, which has even fewer glands than mammals or amphibians. The main special feature of their skin is that the epidermis is heavily keratinized with a layer, which also prevents water loss.</em>

2. Amphibians must lay eggs in water or in moist soil to reduce moisture loss: <em>Because amphibian eggs don't have an amnion, the eggs would dry out if they were laid on the land, so amphibians lay their eggs in water.</em>

3. Reptile egg shells are harder than amphibians' eggs: <em>Reptile eggs are coated with a leathery or brittle coating, and the animals that hatch from them are miniature versions of the full-sized animal parent. In contrast, amphibian eggs are transparent and jelly-like. The animals that hatch from them still must go through metamorphosis.</em>

The classical point of view is that, during mitochondrial respiration, three ATP molecules can be generated from one molecule of
Stells [14]

Answer:

38

Explanation:

In eukaryotic cells, the maximum production of ATP molecules generated per glucose molecule during cellular respiration is 38, i.e., 2 ATP molecules from glycolysis, 2 ATP molecules from the Krebs cycle, and 34 ATP molecules from the Electron Transport Chain (ETC). <em>In vivo</em> (i.e., in the cell), this number is not reached because there is an energy cost associated with the movement of pyruvate (CH3COCOO−) and adenosine diphosphate (ADP) into the mitochondrial matrix, thereby the predicted yield is approximately 30 ATP molecules per glucose molecule. In aerobic bacteria, aerobic respiration of glucose occurs in the cytoplasm (since bacteria do not contain membrane-bound organelles such as mitochondria), and thereby, in this case, it is expected that aerobic respiration using glucose yields 38 ATP per glucose molecule.
