Benign tumors are not cancerous. Malignant tumors are cancerous.
Benign tumors usually aren't problematic while malignant tumors grow and spread quickly putting you in harms way.
Answer: Another example is that the person would be able to interpret the medications that a person needs.
Explanation:
The health area encompasses more than just doctors who are in offices attending patients. This is also the part where a patient has to buy medications and should go to the pharmacy to purchase them. Pharmacists can help the person get what they are looking for and be able to guide them. It is not the same as a person who has no knowledge of drugs from service to one that does.
A person who works in a pharmacy and who does not have the experience in this area of health can make its client not have the best experience when it is looking for the medicine, it could confuse it and get to the point of giving him something that ultimately does not need. Instead, a person prepared in the area can provide a faster service and make the customer feel satisfied.
Many times the pharmacist can identify if the client wants a medication that he does not need. Many times when buying medicine, the pharmacist tends to ask the reason why this medicine was assigned to know if the client really needs it or possibly wants it for other purposes.
I believe the asnwer would be 2 or 3.
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.
