A) To ensure that natural resources are available for future generations
It is true that studies of animals show that they play only when the physical survival needs have been met; however, there is growing evidence that for children, play is crucial in terms of biological evolution as well as individual development.
The skin has only 2 layers—epidermis and dermis. Hypodermis, if that’s what you have in mind as the third, isn’t considered part of the skin.
The epidermis is a barrier to infection, trauma, and water loss (dehydration); it’s important to our social interactions; and it’s the body’s largest sense organ. The dermis provides toughness and resistance to mechanical stress; provides blood vessels that come close to the epidermis and nourish it (but don’t enter it); contains a variety of sensory receptors for touch, heat, cold, pressure, and vibration; and is an arena of immune defense in which white blood cells can rally at a site of infection and fight off intruders.
