Answer:

A. DNA replication

B. Two haploid daughter cells

C. Four haploid daughter cells

D. No, they are not the same

E. Gametes

Explanation:

A) Step 1 and Step 2, according to the image attached to this question, depicts the stages of interphase where the REPLICATION of genetic material occurs i.e formation of sister chromatids.

B) Meiosis occurs in two division steps namely meiosis I and meiosis II. Meiosis I, which involves the separation of homologous chromosomes produces TWO haploid daughter cells.

C). However, in meiosis II, sister chromatids separate to produce FOUR haploid daughter cells.

D) The cells in step 4 are not all the same due to a process called CROSSING OVER, which occurs in the Prophase of meiosis I. Crossing over exchanges chromosomal segments between two non-sister chromatids of homologous chromosomes as seen in the color of the images attached.

E) The four daughter cells produced in step 4 will mature into GAMETES, which will be used in sexual reproduction.

CD4 cells are infection-fighting white blood cells.

<h3>What are CD4 cells?</h3>

White blood cells called CD4 cells also referred to as T cells, are crucial components of your immune system because they combat infection. When a person has HIV, their CD4 count is used to determine how well their immune system is functioning (human immunodeficiency virus).

HIV not only attacks CD4 cells but also makes use of them to spread the infection. HIV uses the CD4 cells' capacity for viral replication to kill CD4 cells by producing more of the virus. The CD4 cells ultimately enlarge and explode as a result of this. HIV weakens the immune system by destroying CD4 cells.
