You do it before a lab so as to prevent contamination of the materials. You might have things on your hands that might contaminate the experiment and the research. You do it after because you don't want to have things from your experiments on your hands because that can be extremely dangerous.

Answer:

The correct answer is: A) reticular dermis.

Explanation:

The dermis is one of the three layers of the skin, and is divided into two layers as well: papillary dermis and reticular dermis.

The papillary dermis has characteristic fingerlike projections called dermal papillae, which extend towards the epidermis (the outermost layer of the skin). These papillae contain blood vessels that nourish the hair follicles and the cells in the lower layers of the epidermis.

The reticular dermis, on the other hand, has no papillae, but instead has a dense irregular connective tissue filled with collagen and elastic fibers. In this region of the dermis is where sudoriferous glands, sebaceous glands, sensory nerve endings, arrector pili muscles, and blood vessels can be found.
