The answer is reflex action. Impulse that triggers a reflex action does not pass through the brain so as to shorten the time for response. It passes through a reflex arch and this is why the muscles are contracted even without time to think of what happened. The sensory and motor neurons only arch at the spinal cord.

The selective serotonin uptake inhibitors, like the antidepressants Prozac, Zoloft, or Paxil, result in increased levels of sero
never [62]

Answer:

increase anxiety; decreased vulnerability to overreact to stress

Explanation:

Serotonin (5-HT) is a natural neurotransmitter that carries signals between nerve cells (neurons) throughout the body. This neurotransmitter (serotonin) is responsible for regulating many biological functions (e.g., mood, digestion, sleep, etc). Moreover, it has been shown that there is an association between low cerebrospinal fluid 5-hydroxyindole-acetic acid (5-HIAA, the principal serotonin metabolite in the brain) levels and the risk of developing depression or destructive behaviors. In addition, serotonin concentration can also be elevated in situations of anxiety and/or stress. Antidepressants such as Prozac, Zoloft and Paxil act as serotonin uptake inhibitors that increase serotonin concentration at the synaptic site. Like other drugs, these antidepressants may lead to increase anxiety and decrease the vulnerability to react to stress by downregulating sensitivity to serotonin released during natural stress situations.

Using Grime’s Triangle as a framework, discuss how natural selection and trade-offs work to form the niche of species.
Jobisdone [24]

Natural selection affects the scope of the niche of a given species. Moreover, trade-offs are associated with differences in traits that also may affect the niche of a species.

<h3>Natural selection and trade-offs </h3>

Natural selection refers to the differential survival or reproduction of individuals in particular environmental conditions.

The different niches occupied by species are mainly a consequence of differential trade-offs among species, i.e., by differential phenotypic features that generate negative correlations among species.

Grime’s Triangle is based on the associations (trade-off) between adaptation to productivity and/or competition, stressful environments (habitats) and disturbance.
