Answer:
B) Two different species of bacteria can share DNA, including antibiotic-resistance genes, during conjugation.
Explanation:
Conjugation is a process by which bacteria can exchange their genetic material between them. So through conjugation, the antibiotic-resistant gene coded by plasmid can be transferred through sex pilus to another bacteria.
So due to conjugation two different species of bacteria can share DNA which can include antibiotic-resistant genes. Therefore, through conjugation genetic variation and evolution are favored in bacteria. So due to this reason conjugation is a very important process in bacteria to spread antibiotic-resistant genes.
Answer:
functional groups
Explanation:
Functional groups are molecules with specific atoms and have their own chemical properties when attached to some other substances. Glucose is a simple sugar and has an aldehyde group (CHO) as its functional group. The presence of CHO in it makes it be present in food without any harmful impacts. On the other hand, hexanoic acid has COOH (carboxylic group) as its functional group. COOH group has a tendency to donate its protons and become ionized. It is toxic as it is reactive and tends to affect the pH of the food or solution in which it is present.
