Answer:
The correct answer is option D, that is, bottleneck effect.
Explanation:
A phenomenon, which occurs due to events like earthquakes, floods, or other natural calamities that result in the severe declination in the size of a particular population is known as the bottleneck effect. The bottleneck effect is an extreme illustration of genetic drift that results in the reduction of a population's genetic variability.
With the decline in the size of a specific population, a reduction in the genetic variability of the same population is witnessed due to the loss of alleles. This eventually makes the population vulnerable to pollution and diseases. Hence, the given case is an example of the bottleneck effect.

Answer:
Cardiac output = 20 L/min
Explanation:
The cardiac output of a person refers to the volume of blood the heart pumps in a minute. The normal range for cardiac output is about 4 to 8 L/min. However, this can vary depending on the metabolic needs of the individual at any instant of time, for example, it is higher when exercising than when resting.
Cardiac output is calculated from the product of the stroke volume in liters/min and the heart rate in beats/min
Cardiac output = stroke volume * heart rate
For the individual who is running; stroke volume = 100 mL/beat or 0.1 L/beat
heart rate = 200 beats/min
Cardiac output =0.1 L/beat * 200 beats/min
Cardiac output = 20 L/min
