Answer:

The diaphragm and rib muscles contract. (Ans B).

Explanation:

Breathing in is the process which is also known as inhalation. Inhalation is a process where taking air and sometimes some other substances, and other gases enter the lungs.

When we inhale or breathe in our diaphragm moves downward and contract. This helps to increase the space in our chest cavity and lungs expand into it. The muscles which are present between our ribs also help to enlarge the cavity of the chest. When we breathe they contract to pull our rib cage both outward and upward directions.

Answer:

In the case of HIV-1, this loss-of-function mutation has proven to be beneficial.

Explanation:

Loss-of-function mutations are those that result in a gene product that has less or no function compared to the unmutated gene. When the allele completely loses function, (null allele), it is called an amorphous mutation. Phenotypes associated with these mutations are usually recessive, except when the organism is haploid, or when the reduced dosage of the normal gene is not sufficient to produce a normal phenotype (this phenomenon is called haploinsufficiency).

As mentioned earlier, this type of mutation results in a defective gene, but the text shown in the above question shows an example of a beneficial loss-of-function mutation because this mutation provides resistance to HIV-1 infection.
