True or false: the body often naturally seeks rest in the afternoon, between 1: 00-4: 00 p. m.

The correct answer is True

Explanation:

Biologically, the human body is regulated by a cycle of rest vs activity; this is related to the circadian rhythm that includes changes occurring during the day and night. According to this cycle, humans experience high levels of alertness and energy during the morning but during the afternoon, especially after 1 p.m. these levels fall, and therefore people feel they need to rest. This is believed to be normal and part of the circadian rhythms although it has also been attributed to the digestive process that occurs after lunch. According to this it is true the body often naturally seeks rest in the afternoon, between 1:00-4:00 p.m.

1) gene flow

- it is described as the transfer of genes from one population to another population so that frequency of gene is increased.

-a zebra migrates to join a different herd of zebras.

2) natural selection

- a mechanism of evolutionary change in which individuals with advantageous traits survive and reproduce whereas the others ( those that can not adapt) eliminate from the population.

-competition for sunlight leads to taller trees.

3) mutation

- permanent change in the nucleotide sequence of dna ( genetic material) that could have harmful or useful consequences.

-the dna of a snake changes to make its venom stronger.

4) genetic drift - it is a random phenomenon ( that occurs by chance such as fire) that results in change in the gene frequency in a small population.    

-a grassfire randomly sweeps through a population of buffalo and kills most of the animals.
