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>
