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.

A). Organisms within a population compete with each other to survive.
Explanation:
Charles Darwin in his evolution theory proposed that the organisms of all species emerge and develop via the 'natural selection' of tiny, inherited discrepancies and these disparities enhance the individual's ability to contest and compete with each other in order to survive and reproduce to continue their existence. This led to the emergence of the phrase 'survival of the fittest' which suggests that in this competition of 'natural selection', only the fittest will survive. Thus, <u>option A</u> is the correct answer.
