Given what we know, we can confirm that the type of media which allows the growth of different microbes while still being able to distinguish between them is called a differential media.
<h3>What is a differential media?</h3>
- It is a type of media that allows for the growth of many different microbe types.
- This media is special in that it allows the user to still distinguish between the microbes.
- This is done primarily on a basis of the biochemical differences between the microbes.
Therefore, we can confirm that a differential media is a type of media that allows the growth of different microbes while still being able to distinguish between them, focusing on biochemical differences of the two colonies grown.

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.

Answer:
Mutation rates increase substantially in cells defective in DNA mismatch repair or in homologous recombinational repair (HRR). Chromosomal rearrangements and aneuploidy also increase in HRR defective cells. Higher levels of DNA damage not only cause increased mutation, but also cause increased epimutation.
Answer:
The parietal bone has not articulated with zygomatic bone.
Explanation:
Parietal bones are paired structure that form the roof and side of the cranium.
The parietal bones are articulated with each other and form suture.
It articulates occipital bone posteriorly,and anteriorly with the frontal bone which form a suture called as coronal suture.
Inferiorly the parietal bone is articulated with sphenoid and temporal bone.
Zygomatic bone is irregular shaped and paired structure that articulates with maxilla.temporal bone, sphenoid bone,frontal bone.
