Answer:

4. DNA replication occurs before the division of the nucleus.

5. The question is incomplete, the diagram of the question has been attached as an image. The correct answer is meiosis.

6. Ovary cells.

Explanation:

QUESTION 4:

Before any cell undergoes division; whether meiosis or mitosis, its DNA must be replicated or duplicated in order to ensure that each daughter cell receive the correct number of chromosomes. This process of DNA replication involves the unwinding of the double-stranded DNA by HELICASE, and the synthesis of a new DNA strand.

N.B: Meiosis occurs only in reproductive cells.

QUESTION 5:

The diagram has been attached. It displays a female reproductive system showing the fallopian tube where the female gamete (ovum/egg) passes. The egg which is labelled X is produced by the ovary during meiosis.

Meiosis is the cell division that results in daughter cells (gametes) with each having their chromosome number reduced by half. i.e. a diploid (2n) female will produce haploid eggs (n)

QUESTION 6:

Meiosis occurs only in reproductive cells. It is a cell division that gives rise to gametes or sex cells used during reproduction. Ovary is the female reproductive organ that produces the female gamete (egg). Meiosis occurs in the diploid germ cells of the ovary and results to haploid cells called egg or ovum.

Blood flows to the brain through the _____ arteries and away from the brain through the _____ vein.
Evgesh-ka [11]
Blood flows to the brain through the internal carotid and vertebral arteries and away from the brain through the internal jugular vein. The internal carotid artery supplies the brain, while the external carotid nourishes other portions of the head, such as the face, skull, scalp and the meninges. The vertebral arteries provide supply to the upper spinal cord, brainstem, cerebellum, and the posterior part of the brain.
