The question is incomplete. The complete question is as follows:
A treatment for bacterial infections from the early 20th century has made a comeback-the use of bacterial viruses to eliminate bacterial infections. Which explanation most accurately describes this mechanism of action behind this treatment?
A. A wide variety of bacteria cause a large percentage of human infections, producing much sickness and death.
B. Viruses can infect bacteria, transferring pathogenic genes. The viral genes can then be suppressed, causing the bacteria to not replicate viruses.
C.The attachment structures on the virus and the receptors on the host cells make for exquisite specificity of viruses for particular bacterial species.
D. Antibiotic resistance in humans is on the increase, so using a different kind of therapy is more beneficial.
Answer:
Option (C) and (D).
Explanation:
The pathogens are the organisms that can cause harm to the living organisms. Various strategies and drugs has been research to kill these pathogens
The viruses can also be used to treat the bacterial and viral infections. This methodology was used in the early 20th century but has come back because the antibiotics that are given makes the bacteria resistance against the particular treatment. The virus and bacteria has some specific and unique receptors that provide specificity of the virus against the bacteria and can be used for the treatment.
Thus, the correct answer is option (C) and (D).
Answer:
Gametic cells.
4 cells.
Chromosomes number reduces to half.
Explanation:
Meiosis may be defined as a type of cell division in which a single parent cell divides to form the daughter cells. The sex cells or gametes (sperm and ova ) undergoes the meiosis division.
The single parent call divides into four daughter cells by the process of meiosis- I and meiosis- II. Meiosis II is similar to the process of mitosis.
Meiosis is also known as reduction division. The chromosome number reduces to half as compared with the parent cell. The haploid cells are produced in the meiosis.

The most important consideration when issuing a clinical practice recommendation for a preventive service across a large population is that the preventive services causes no harm.
<h3>What are preventive services?</h3>
Screenings, check-ups, and patient counselling are all part of routine health care is referred to as preventive services.
Preventive care can significantly increase your lifespan because it allows you to detect problems early and treat them more effectively.
For example, if one practices weight management and lose excess weight/keep it off, you will live longer and avoid serious diseases such as type 2 diabetes and heart disease.
Thus, the most important consideration when issuing a clinical practice recommendation for a preventive service across a large population is that the preventive services causes no harm.
