<span>heterozygous / homozygous refers to whether both alleles for a gene are the same. The organism is homozygous if both alleles are the same - that is, either both are dominant or both are recessive. The organism is heterozygous if the alleles are different - that is, if one allele is dominant and the other allele is recessive..
the answer to the questions is A. </span><span>One parent was heterozygous for eye color and the other was homozygous with red eyes.</span>
True. Mitosis is<span> a type of cell division that results in two daughter cells each having the same number and kind of chromosomes as the parent nucleus, typical of ordinary tissue growth and meosis is </span><span>a type of cell division that results in four daughter cells each with half the number of chromosomes of the parent cell, as in the production of gametes and plant spores.

Answer:
D. It keeps the temperature lower for sperm development
Explanation:
<u>Semineferous epithelium ,of the seminiferous tubules, of the testis is the site of sperm production (Spermatogenesis) , and highly sensitive to elevated and fluctuating body temperature of man. Elevated temperature affect the survival of spermatids , the spermatozaon, and therefore affects spermatogenesis</u>.
To avoid this the testis is located outside the body in the scrotal sack.This positioning aids shielding away of the elevated body temperature; thereby survival of spermatozoan.
The attachment in the scrotal sack is done by the cremasteric muscles of the scrotum. This muscle positions the testis in the best angle to reduce temperature conduct from the body.
It also help by contracting and relaxing, to adjusts the temperature of the testis depending on the environmental temperature.During cold showers,it constricts pulling it close to the abdomen, and after, relaxes returning it to normal position.
