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.
Answer:
Explanation:the cranial end of the neural tube closes by 24days and the caudal 25-36 days . Defective closure of the neural tube result in neural tube defects (NTDs) . it also depends on the point of the defect , NTDs may also affect the brain and spinal cord.

<u>Answer:</u>
<em>The two major processes by which bacterial populations produce genetic diversity are gene transfer and mutation.</em>
<u>Explanation:</u>
Gene transfer in bacteria occurs through conjugation. In the process of conjugation, the plasmid gets transferred from bacteria to another. Mitosis leads to the formation of two identical individuals.
In this process, the chromosome and the DNA content of the daughter cell remains the same as the mother cell. Bacteria also divides by the process of binary fission.
