You’re answer to this question would beD
Answer: option A
Explanation: As demonstrated by the Hardy-Weinberg principle, the dominance or recessiveness of an allele does not determine its frequency in a population.
Answer:
B) Viruses are killing some of his B cells and becoming incorporated into the genomes of others.
Explanation:
Epstein-Barr virus causes infectious mononucleosis by following mechanism.
1) Epstein-Barr virus attaches to and infects epithelium of the throat where it replicates and causes pharyngitis.
2) Virions enter the lymphoid vessels and are carried to the lymph nodes. Some virions escape the lymphnode trap and are carried to the bloodstream.
3) Virions attach specifically to B lymphocytes and infect them, producing either latent infection or productive infection.
4)The infected B lymphocytes actively replicate and differentiate into cells producing random immunoglobulins.
5)T cells respond to infection and destroy the lymphocytes replicating EBV vitus.
6) Latently infected B lymphocytes become immortal. They are not attacked by T cells.
B. the speed of the water
Explanation:
The independent variable here is the speed of the water being poured through the tube.
An independent variable is the variable is the whose change does not rely on another.
- The speed of the water is the cause of the sand deposition.
- This is the independent variable.
- The quantity of sand that is deposited is the dependent variable.
- It relies on the speed of the water.
- The dependent variable is the effect of the speed of water being poured.

The piece of cheese in the refrigerator had the least amount of chemical change.
- Moulding occurs on substances which are warm and moist
- Mold thrives in warm and humid places
- In refrigerators, the environment is cool and dry
- This environment hinders the growth of mold
- The bacteria and fungi require optimum temperatures to flourish, which is not present in a refrigerator
- The cheese placed outside and on the counter will grow mold as those environments do not arrest the growth of mold
- Refrigeration ensures that food is not spoilt
Therefore, the least amount of chemical change takes place on the cheese placed in the refrigerator.
