Answer:
B. the input zone of a nerve cell.
Explanation:
Dendrites are the small extensions that come out of the soma or cell body of a neuron. The function of dendrites is to receive the nerve signals or information from the axons of the presynaptic neurons and carry them towards the cell body or soma. In a synapse, the signals from the axons of the presynaptic neurons are revived by dendrites of postsynaptic neurons. The plasma membrane of dendrites have receptors to which the chemical messengers from other cells bind. In this way, dendrites serve as input zone of a nerve cell.
Answer:
D. is responsible for most of the skin's structural strength.
Explanation:
A. contains no blood vessels.
False. The dermis contains blood vessels together embedded in it along with the sweat and sebaceous or oil glands, hair follicles, and nerve endings.
B. functions as a padding and insulation.
False. The fat layer that is located below the dermis is the one responsible for padding and insulation.
C. is divided into three distinct layers
False. The dermis is divided into only two separate layers. These are the papillary layer or the upper layer and the reticular layer or the lower layer.
D. is responsible for most of the skin's structural strength.
Yes, the dermis functions for providing the skin's structural strength because of it's thick fibrous and elastic tissue layer. This layer consists primarily of collagen and elastin that also allows for the skin's flexibility.
E. is made of epithelial tissue.
False. The dermis is made up of fibrous and elastic tissue. It is the epidermis which is composed of the epithelial tissue.
Answer:
A
Explanation:
Organisms on Earth use nitrogen to build proteins necessary for cell
development.
A fever is an abnormal elevation of the body temperature. A low to moderate fever, when a low to moderate fever, when allowed to run its course, can be beneficial. fever can promote interferon activity. Fever can also accelerate tissue repair. lastly, fever will inhibit the reproduction of bacteria and viruses.
It is important to note that fever is not an illness, however, it is a symptom, or sign that your body is fighting an illness or infection. Fever stimulates the body's defenses, sending white blood cells and other "fighter" cells to fight and destroy the cause of the infection.
