Answer:
<u>the bottleneck effect</u>
<u />
Explanation:
Genetic drift has an important impact on the small populations. mutations, which are spontaneous heritable changes in the genetic code, made up of DNA. Here, mutations accumulate over time in a group, modifying the distribution of alleles or various forms of a gene. Natural selection may result in a loss of diversity in a population called genetic drift; one trait's allelic frequency rises while others become less prevalent. Typically such differences exist because of occurrences of mutation and recombination.
Some mutations or alleles may become extinct from the population.
<u />
Variants of a gene accumulate and are transmitted across generations; the frequencies of these occurrences are altered and become more stable in genetic drift- they become genetically distinct and may eventually form a new species after isolation. This may be further compounded through other phenomena such as the founder effect where a group separates and genetic diversity decreases; and the bottleneck effect where barriers to reproduction or the die-off a population increases genetic drift.

According to the research, the correct option is false. The colon can be divided into four sections: ascending, transverse, descending and sigmoid.
<h3>What is the
colon?</h3>
It refers to the portion of the large intestine, whose function is to convert digested food waste (chyme).
It can be divided into four sections:
- Ascending, it begins at the junction with the tenuous intestine and extends down the right side of the abdomen.
- Transverse, which crosses the abdomen from the right side to the left.
Therefore, we can conclude that according to the research, the correct option is false. The colon can be divided into four sections: ascending, transverse, descending and sigmoid.

The gene pool. This is the series and combinations of genes in the environment. This can affect the human adaption of the environment and how they cope up with the species living with them. They interact with them in a way that the species can affect one another,
Answer:
Both cardiac and smooth muscle are involuntary while skeletal muscle is voluntary.
Explanation:
Hormones
The endocrine system includes various glands in the body that are responsible for secreting hormones into the bloodstream. Hormones are chemical substances produced by the body that regulate certain functions of cells and organs. Hormones can regulate sleep, sex, growth, stress, huger, metabolism, etc.
