plzzz answer it fast...

Answer 1

Answer:

1. The male has reproductive organs, or genitals, that are both inside and outside the pelvis. The male genitals include:

## the testicles (TESS-tih-kulz)

## the duct system, which is made up of the epididymis and the vas deferens

## the accessory glands, which include the ## ## seminal vesicles and prostate gland

## the penis

2. 46 chromosomes

Cells of human being have 23 pairs of chromosomes, 22 pairs of autosomes and one pair of sex chromosome. Hence, each individual has 46 chromosomes in their cells. Hence, the number of chromosomes present in a nerve cell of a human being are 46 chromosomes.

3. The sperm is a haploid cell means it contains half the number of chromosome of the parent cell. A human contains 46 chromosomes in it. Thus, mature sperm contains 23 chromosomes. After fusing with the egg (haploid cell), the sperm (haploid cell) forms zygote which is diploid..
