What takes place when you inhale and exhale ?

Answers

Answer 1

Answer: When you inhale and exhale, you actually breathe. When you inhale, your intercostal muscles between ribs and diaphragm contract. This increases the space in chest cavity so your lungs can expand and the air enters the lungs. When you exhale, intercostal muscles and diaphragm relax reducing the space in the chest which leads to removing the air from the lungs.

The three domains in the woese system of classification are:.

Answers

Given what we know, we can confirm that the three domains included in the Carl Woese classification system are archaea, bacteria, and eukaryote domains.

What is a classification system?

This is a system used in biology to group living organisms based on similar traits or genetic origins. It is used to better study organisms and their relationships to one another. Carl Woese proposed the system of archaea, bacteria, and eukaryote domains.

Therefore, we can confirm that the three domains included in the Carl Woese classification system are archaea, bacteria, and eukaryote domains.

Half of the polar bears in a small population die. This population may experience changes due to _____. gene flow mutation genetic drift natural selection

Answers

Correct answer: Genetic Drift

Genetic drift is defined as the random change in the allele frequency of a population is changed by chance or due to random changes in the environment. It is a random process that can lead to large changes in the overall population in a short period of time. It is a mechanism of evolution and it does produce the adaptation.

Hence, the correct answer would be genetic drift.

Answer:

Genetic Drift

Explanation:

Genetic drift refers to the evolutionary agent that brings about the changes in the gene pool of the population by some chance event. In the given example, half of the polar bear population was wiped out of the habitat by any chance event such as natural calamity, epidemic disease or any other random events. Since no mutation or natural selection was responsible for the death of polar bears, it is an example of genetic drift.

Genetic drift is more effective in small populations. And the size of the population of the polar bear was also small to allow the genetic drift to cause the changes.
