Answer:
b. adrenal medulla
Explanation:
The gland responsible for the "fight or flight" response is the adrenal medulla. The nervous system sends out an impulse to smooth muscles and glands that tell the adrenal medulla to release adrenaline and noradrenaline into the bloodstream. Once they are released into the bloodstream and circulating through the body, it brings changes such as your breathing getting quicker and quicker and your heart pounding more and more.
The right answer is Thanh's grade is 2.5 standard deviations below the mean of the test grades.
The z scores are standard deviations. If, for example, a tool returns a z score of +2.5, it means that the result is a standard deviation of 2.5.
Very high or very low (negative) z scores associated with very low p values are at the ends of the normal distribution.
Answer:
Population Bottleneck
Explanation:
Population Bottleneck refers to the evolutionary events that result in drastic reduction in population size of a species. It may be caused by any environmental factors such as natural disasters or man activities such as hunting. Population bottleneck reduces the population size to the level of its extinction.
However, species conservation programs could have resulted in increased in the population size back. Hence, the population experienced "population bottleneck".
