The term that can be used to describe evolution by natural selection is SCIENTIFIC THEORY.
Theory means "the best explanation so far."
Scientific theory is a work in progress. It is a well-substantiated explanation of some aspect of the natural world that is acquired through the scientific method, and repeatedly confirmed through observation and experimentation.
<span>An oceanographer would be most likely to study how whales are affected by pollution. An Oceanographer is a scientist that studies all aspects,physical and biological that pertain to the ocean. The topic of whales and pollution can fit under the study of ocean ecosystem dynamics which falls under the large umbrella of oceanography.</span>
Answer:
The cell organelle stores water for plant cells is vacuole.
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.
Fossil fuels are considered a nonrenewable energy source because once fossil fuels are used, they are gone. So, the correct option is A.
<h3>What do you mean by Nonrenewable energy?</h3>
Nonrenewable energy may be defined as that energy that once consumed can not be replenished for millions of years.
Fossil fuels are examples of nonrenewable energy resources. The formation of fossil fuels may take over millions of years. This fuel is made naturally by the decomposition of dead and decayed organic living matter.
Therefore, the correct option for this question is A.
