A. kill, prevent, living tissues
B. kill, prevent, non-living objects
C. increases, decreases, living tissues
D. kill, increases, non-living tissues

Answer 1

Antiseptics are the chemicals used in the form of solution or cream. Antiseptics are applied to the cuts and wounds. Antiseptic works against infection caused by a microorganism that grows on wounds.

Complete answer:
The chemical substances used to reduce the chance of microbial infection on the cuts and wounds are known as antiseptic such as furacine.
Cut and wounds open our living tissue to contact with the environment. Microorganisms such as bacteria that can easily grow on wounds and cut and cause the infection. The bacterial infection can convert the simple cut and wounds into a disease.
Antiseptic kills the bacteria or can prevent form bacteria, this depends upon the chemical composition of the antiseptic.
So, antiseptic is the chemical which either kills or prevents the growth of microorganisms and is applied to the living tissues.
The common and much known antiseptic is the tincture of iodine which is a potassium salt solution in ethanol.

Therefore, option (A) kill, prevent, living tissues, is correct.

Note: The antiseptics are used on the living surface such as wounds and cuts on a human body. The chemical compounds used on non-living objects are known as disinfectants. The antiseptics have a lower concentration of chemical compounds because a high amount can irritate the body whereas the disinfectants have a higher concentration of chemical compounds. The antiseptics and disinfectants, both kill, prevent or decrease the microorganism, never increases. Antiseptics are different from antibiotics. Antibiotics also either kill or prevent the growth of microorganisms but are not applied to the living tissues. Antibiotics are taken into the body in liquid or tablet form.
