I believe the answer is a and d and b not 100% sure
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.

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.

Explanation:
A) First of all, it must be considered that HIV has a RNA genome.
The reverse transcriptase is a viral enzyme able to convert a RNA molecule (in this case the RNA would be the viral genome) to DNA. This process is important for two reasons:
* The DNA molecule is more stable than RNA --> Therefore, there is a higher likely that the molecule wouldn't be degradated by the host.
* The viral genome made of DNA will be integrated into the host genome --> To do so, it requires to be DNA instead of RNA
B) The inibitor is able to target the Reverse Transcriptase --> So, the likehood of converting RNA to DNA is lower. In this case, the single RNA molecule is less stable than the DNA and the host can degradate it more easily.
C) In general, the viral will not survive the treatment and, hence, the patient will not suffer from the viral infection

Homeostasis:
In biology, homeostasis is the state of steady internal, physical, and chemical conditions maintained by living systems. This is the condition of optimal functioning for the organism and includes many variables, such as body temperature and fluid balance, being kept within certain pre-set limits.
It’s color, texture, scratch, and toughness.
