Answer:
The correct answer is A. Brief stressors lead to changes in cytokine production.
Explanation:
Cytokines form an important group of proteins that act as mediators of communication between living cells. They can exert their action in a paracrine way (between neighboring cells within the same tissue), or endocrine (between cells located in different tissues). The imbalance on the immune system that stressful events exert is an increase in the production of pro-inflammatory cytokines and their associated spectrum of age-related syndromes and diseases. Proinflammatory cytokines are soluble mediators that promote and mediate inflammatory processes, the following stand out: interleukin 1 (IL-1) is involved in the regulation of the immune process and inflammation; interleukin 6 (IL-6) that also serves as a link between the endocrine system and the immune system; and Tumor Necrosis Factor (TNF), which has the ability to destroy certain cell lines and initiate the cascade of pro-inflammatory cytokines and other mediators.

The calcium that triggers muscle contraction is stored in synaptic vesicles called endoplastic reticulum. that is not the only function of the endoplastic reticulum it is also a network of a membranous tubules within the cytoplasm of a eucryotic cell continuous with the nuclear membrane.
<span>The types of individuals in a population that are represented by the two ends of a bell curve are those with an extreme variation of a specific trait. The bell curve is a normal distribution. It is the most common type of distribution. The greatest part of the distribution belongs to the variations of a trait near to the average value. However, two ends of the bell curve belong to individuals with an extreme variation of the trait.</span>
