Answer:
A. It is the place where energy is produced.
It stores the genetic information, the DNA (chromosomes).
Explanation:
The controlled experiments are performed by the scientists, when they want to study the changes in the sample on changing a single variable. So, the correct answer is option (b).
In case, all variables are kept same, no changes would be observed in the experiment sample. A controlled experiment can be performed on living thing as well as non living. But, controlled experiment cannot be performed on the things which are influenced by a lot of variables, as they cannot create realistic results. So, the option (a), (c), and (d) are incorrect.
Answer:
The process of reuptake occurs when the sending neuron normally reabsorbs excess neurotransmitter molecules.
Explanation:
The process of reuptake takes place when a cell that initially produced and emitted a particular substance reabsorbs it again. Serotonin is one of the secretions affected by this process since it can be reabsorbed if it sticks to receptors located in the original nerve where it was produced to be then released once again.

The epithelial cell will have 38 chromosomes
A 2n or 2(19) = 38 chromosomes. This is because n is called haploid number of chromosomes; the number of chromosomes present in the gametes. Epithelial cells like other body cells divides through the process of mitosis; therefore; the parent cells yields daughter cells with the same number of chromosomes (diploid). The other haploid (n) number is present in the gametes which divides by the process of meiosis.
