butalik [34]

Answer & Explanation:

1:

One reason you may feel tired is because your body is fighting off the disease/infection/sickness. There are many ways the body fights it off, 1 way being fever. Fever makes the infection burn itself to death. A side effect of fever is tiredness and chills.

There is no cure for the cold but it can be treated with citrus (oranges, cough drops, etc). The average person has about 2-3 colds a year, they can be brought on by weather changes, especially in the fall. The body can get over the cold in anywhere from 1-5 days. Some individuals will have worse symptoms than others.

In hospitals, it was common practice to clear the air bubble from a syringe by expelling a small amount of the syringe contents
mina [271]

Answer:

The ejection of syringe contents is to remove air bubbles that can be detrimental to patient health. When antibiotics are repeatedly released this way, microflora in the environment are exposed, albeit at non-lethal doses, which causes said micro-organisms to begin to develop means of neutralizing such antibiotics, thereby contributing to antibiotic resistance and mutations. Also, some syringe contents may not be anti-biotic in nature but they can have mutagenic effects on microbial genome at such concentrations.

Explanation:

Antibiotic resistance is the ability of bacteria or other microbes to resist the effects of an antibiotic. Antibiotic resistance occurs when bacteria change in some way that reduces or eliminates the effectiveness of drugs, chemicals, or other agents designed to cure or prevent infections. The bacteria survive and continue to multiply causing more harm
