Answer:
Active transport
Explanation:
Active transport is the movement of molecules across a cell membrane from a region of lower concentration to a region of higher concentration—against the concentration gradient. <u>Active transport requires cellular energy to achieve this movement.</u>
I think the best medium is agar. It is a jelly-like substance that is obtained from algae, and is used to culture small organisms such as microorganisms and bacteria.
Hope this helps. :)
During DNA replication, the two strands separate as the hydrogen bonds connecting the parent strands are broken by an enzyme called helicase. In the DNA molecule (double strand) complementary bases are joined by hydrogen bonds; that is; Adenine paired to thyamine and guanine to cytosine; during replication the enzyme helicase separates the double helix by breaking the hydrogen bonds between the complementary bases.
Answer:
Bacteriostatic
Explanation:
The antibiotics are the compounds which are used to treat the bacteria and are of two types: the bacteriostatic and bactericidal.
The bacteriostatic antibiotics are the antibiotics that do not kill the cells but they stop the reproduction of the bacteria and keep them in their stationary phase.
In the given question, since the antibiotic does not kill the cell but stops the doubling that is reproduction therefore the antibiotic is bacteriostatic.
Thus, bacteriostatic is correct.
