Functions of skin. Protection: it protects against UV light, mechanical, thermal and chemical stresses, dehydration and invasion by micro-organisms. Sensation: skin has receptors that sense touch, pressure, pain and temperature. Thermoregulation: various features of the skin are involved in regulating temperature of the body. For example sweat glands, hair, and adipose tissue. Metabolic functions: subcutaneous adipose tissue is involved in production of vitamin D, and triglycerides. This diagram shows the layers found in skin. There are three main layers: the epidermis, dermis and hypodermis. There are also sweat glands, and hairs, which have sebaceous glands, and a smooth muscle called the arrector pili muscle, associated with them. Hairs are only found in thin skin, and not in the thick skin present on the fingertips, palms and soles of your feet.
As seen in Graph 1, a pie chart represents the total percentage of cells in each stage of the cell cycle. Interphase accounted for 95.31 percent of the cells, followed by prophase with 1.58 percent, metaphase with 1.27 percent, telophase with 0.95 percent, and anaphase with 0.87 percent. Graph 2. As seen in Graph 2, this pie chart represents the total number of minutes per cycle a cell spends in each stage.
Telophase is the fifth and final phase of mitosis, the process that separates the duplicated genetic material carried in the nucleus of a parent cell into two identical daughter cells. Telophase begins once the replicated, paired chromosomes have been separated and pulled to opposite sides, or poles, of the cell.
