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.
Answer:
A
Explanation:Her liver is not able to break down the alcohol as easily as it is suppose too. She is scarring her liver which is cause build up in her abdomen. I am not sure if this is the correct reason why, but I know it is A.
There are only 3 sites for intramuscular injections, most commonly the deltoid then the ventrogluteal, and lastly the vastus lateralis for infants. If the site is a "hard muscle" or when the muscle is in constant spasm, then an intramuscular injection should not be done. Other reasons why an intramuscular injection cannot be done on a specific site are (1) atrophied muscle on an emanciated patient (i.e. malnourished or cachectic patients), (2) skin infection overlying the muscle group, and (3) the dorsogluteal muscle as this can hit the sciatic nerve and cause paralysis and other neuropathy of the ipsilateral leg.
