Ответ:
The layer that contains keratinized cells which allows for the strength and flexibility of the skin is found in epidermis and makes up 90% of the cells present.
The layer that contains papillae, which creates adhesion between both skin layers and gives nourishment to the epidermis layer is the dermis.
Ответ:
More branching or folds.
Explanation:
Adaptation may be defined as the ability of the organism to adapt and survive according to its environment. Physical, physiological and chemical changes occur in the body of organism for the adaptation process.
The evolution of the increase in the size of the animals might also changes their internal physiology. The lungs and digestive tract also evolved as the size of the organism get bigger. The lungs has the alveoli to increase the surface area and inhalation of more oxygen in the body. Digestive system has villi or folds that increases the surface area for digestion and absorption.
Thus, the answer is more branching or folds.
