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: This is TRUE for me. Osteoporosis is a preventable disease.
Explanation:
In this condition, bone density ( the amount of bone tissue) is reduced because it's deposition does not keep pace with resorption. Although the bone is adequately mineralised, it is fragile and microscopically abnormal, with loss of internal structure.
Peak bone mass occurs around 35 years and then gradually declines in both sexes. Lowered oestrogen levels after the menopause are associated with a period of accelerated bone loss in women. Thereafter bone density in women is less than in men for any given age. That is why in North America, one-third of all women experience fractures because of this disease, amounting to about 2 million bone fractures per year.
Common features of osteoporosis are:
--> skeletal deformity: gradual loss of height with age, caused by compression of vertebrae.
--> bone pain
--> fractures: especially of the hip ( neck of femur), wrist and vertebrae.
It is TRUE for me that some risk factors can't be changed ( which is the low oestrogen levels that occur after menopause in women) but others, such as poor calcium intake, can.
Exercise and Calcium intake during childhood and adolescence are important in determining eventual bone mass of an individual and in preventing risk of osteoporosis in later life.
One of the main medical reasons as to why one might avoid vaccination is that the individual may present allergies.
Allergic reactions can range from mild to severe and <em>life</em>-<em>threatening</em>. <u>Mild allergic </u>reactions will <em>rarely </em>be a solid reason to avoid vaccination, however, there are cases in which one might present severe allergic reactions to the <u>contents </u>of a vaccine.
Therefore, we can confirm that one of the<em><u> only and main reasons </u></em>to not get vaccinated is if your physician has instructed you to avoid the vaccine due to a possible severe allergic reaction.

Answer:
The best answer to the question: Generally speaking, power exercises should be performed before strength exercises, would be, A: true.
Explanation:
In terms of general training, the idea is always go from broader to specific. In that sense, power exercises will allow the body to start mobilizing large groups of muscles, and not focus on only one region, or one specific muscle. According to all the research on proper training, and the correct order in which these two types of exercises: power training and strength training, should be, it says that power training comes first, because power training allows for large groups of muscles to mobilize and thus will maximize the capabilities of the muscles. Then, strength exercises will be initiated to work on specific muscles, or much smaller groups of muscles. This is why the answer is A.
