Answer:
Water distribution on Earth greatly affect settlement of population because water is a necessary item for the survival of living creatures. Without water there is no life. Availability of water increases vegetation and increases the beautification of the area and peoples are attracted to live there.
Those areas where plenty of water is available having maximum population while those areas where water is present in low quantity, the population is also low like deserts.
Answer:
Emotion is an organism's response to a stimulus that includes a mixture of physiological arousal, expressive behaviors, and conscious experience.
Explanation:
What is an Emotion?
Emotion is a neural drive that moves a living organism to action, provoking automatic reactive behavior that has been adapted through evolution as an survival mechanism to meet a survival need. In simple words we can say that Emotion is a mental state related with the central nervous system, several chemical messengers released in neural signal transmissions are responsible for different emotions like happiness, sadness, difference in thoughts etc
The answer is <span>The q allele will go up.
Let's assume that the population is in the Hardy-Weinberg equilibrium and there are only two alleles of some gene. </span>The Hardy-Weinberg principle can be expressed as p + q = 1 where p is the frequency of the p allele and q the frequency of q allele.
Let initial frequencies be:
p = 0.6
q = 0.4
p + q = 1
0.6 + 0.4 = 1
Now, after the environmental change, the frequency of the p allele has gone down, for example p = 0.3
So, p goes from 0.6 to 0.3.
The frequency of the q allele can be calculate using Hardy-Weinberg principle:
p + q = 1
q = 1 - p
q = 1 - 0.3
q = 0.7
Thus, q goes from 0.4 to 0.7.
