dolphi86 [110]

Answer:

The correct answer is- adaptive radiation

Explanation:

Adaptive radiation is the evolutionary process which allow the evolution of many species from a single species because some population of that species get into an environment which is different from their old environment in terms of food availability, predators, etc.

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>

<u><em>Hope this helps you have a better understanding:) !!</em></u>
