Answer:
The correct answer would be B. the population is evolving.
It can be explained with the help of natural selection. It is a natural phenomenon by which organisms which are better adapted to the changing environment have better chances to survive and reproduce.
It leads to a change in the allele frequency of that trait in a population.
For example, in the given population, the allele frequency of red fur increases from 20 to 30 percent. That means the population is evolving to adapt to the changing environment.
When you are performing aerobic exercise at an intensity near VO₂ max, the predominant oxidative substrate is carbohydrate.
The maximum rate at which our body can use oxygen during exercise is known as VO₂ max. When one exercise as hard as they can, their VO₂ max evaluates how much oxygen (often measured in milliliters) they breathe in. The body may use a greater amount of energy the more oxygen one breathe in. Better physical fitness typically translates into a higher value. Most people agree that the best measure of cardiorespiratory fitness is this value. It displays the maximum amount of oxygen the body can take in while exerting itself. The more oxygen the body can consume, the better is aerobic fitness, and the higher is the value of VO₂ max.

Hello! The answer is cell
Answer:
The correct answers are:
1. closing
2. the ventricles and arteries,
3. a constricted trachea
Lub is the first sound of a heartbeat and is mentioned as S1. It is usually produced due to the closing of tricuspid and and mitral or bicuspid valves present between atria and ventricles.
Tricupsid is located between atrium and ventricle of the right hand side and mitral valve is located between atrium and ventricle of the left hand side. They prevent the back flow of blood from ventricles to their respective atria.
Dub, being the second sound is written as S2. It is produced due to the closing of pulmonary (located between right ventricle and pulmonary artery) and aortic valves (located between left artery and aorta).
These valves prevent the back flow of blood from arteries into the ventricles.
The time between the two sounds is often taken as the measure of the diastole i.e. ventricular filling.
Wheezing refers to a high-pitched sound produced when a person breathes, especially during exhale. It is caused by constriction of the airways or inflammation. It is considered as a symptom of various diseases such as asthma, COPD, allergies, bronchitis etc.
