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.
Therapsids are a group of mammal like reptiles that share many features of the body. So basically what this means is that these animals from the Therapsids helps the humans evolve. Therapsids had canine teeth and so do mammals. Their jaws where structured similar to ours and so were their teeth. Their molars were in the back so they chomp their food like meat, just like the humans. The reptiles in the Therapsids group have legs that were more vertical from their body like humans. Where other reptiles did not, they had legs that were sprawled out from their body.The reptiles in the Therapsids group also had turbinates bones like humans. They were also thought to be warm blooded just like humans. There are some similarities that could leave one to believe that there is a connection, but I don’t think so. I think that humans have a more thing in <span>common with chimpanzees</span>
