Answer 1

Answer:

A student adds antibiotic to the animal cell culture medium and still obtains the same growth curve because, Antibiotics don’t have any affect on animal cells

Option D

Explanation:

Antibiotics are substances that inhibit the growth or multiplication of bacteria. Antibiotics are of two types bacteriostatic that is it maintains the count of the bacteria and prevents the multiplication of bacteria or bactericidal that is they kill the bacteria.
