In a sample of 2,400 people, 1,482 were found to have the dominant (taster) phenotype. Assuming that the population is in Hardy-
Alex_Xolod [135]

Answer:

1128.

Explanation:

The dominant taster phenotype is 1482.

The recessive taster phenotype = 2400 – 1482 = 918 .

Recessive phenotypes = 2400 – 1482 = 918

The recessive phenotype frequency = q² = 918 / 2400 = 0.38.

the recessive allele frequency q = √0.38 = 0.62.

The dominant allele frequency, p = 1-q = 1- 0.62 = 0.38

The heterozygous frequency =  2pq = 2 ×0.38 × 0.62 = 0.47 .

The heterozygous individual in the population = 0.47 × 2400 = 1128.

Thus, the answer is 1128.

4. Which of the following describes a long term effect of exercise on<br> breathing rate?
igor_vitrenko [27]

Answer:

Effects of exercise on breathing

During exercise there is an increase in physical activity and muscle cells respire more than they do when the body is at rest.

Woman jogging along a tree-lined path in a park.Exercise increases the rate and depth of breathing

The heart rate increases during exercise. The rate and depth of breathing increases - this makes sure that more oxygen is absorbed into the blood, and more carbon dioxide is removed from it.

The rate of breathing can be measured by counting the number of breaths in one minute. The depth of breathing can be measured using a spirometer (a device that measures the volume of air inhaled and exhaled).

To investigate the effects of exercise on breathing, record the rate of breathing for a few minutes when the person is at rest. After they do some exercise, record their rate of breathing every minute until it returns to the normal resting value.
