It protects body from damage, from loss of water, from abrasion from outside and even protects the deeper tissues.

People who misuse or overuse antibiotics may become resistant to them.<br> a. True<br> b. False
love history [14]

Answer:

True.

Explanation:

Antibiotics may be defined as the chemicals that are required to stop the growth and kill the other living organism. These antibiotics have been developed against bacteria, fungi and microorganisms.

The excess use of the antibiotics leads to the development of the resistant strain against that particular antibiotic. People should not overuse or misuse  the antibiotics as they may become resistant and antibiotics will not effect the pathogens of that individual organism.

Thus, the correct answer is option (a).
