Answer:

monoallelic gene expression

Explanation:

<em>Monoallelic expression is a type of gene expression where only a copy out of the two copies of a gene is expressed and the other is silent. </em>

A gene is usually represented by two alleles representing alternate forms of the same character. Individuals inherit an allele each from their two parents for every gene within their genomes.

When only one of the alleles is expressed for a particular gene while the other allele remains silent, such phenomenon is referred to as monoallelic gene expression.

Annette [7]

Ecdysis

Ecdysis is the name of the process in which an arthropod sheds its exoskeleton and forms a new one.

Ecdysis is the process in which an arthropod or an insect shed its outer cuticle (exoskeleton), and forms a new one. Ecdysis is an essential process in the growth and development of organisms. In arthropds, this process takes place after various steps that are caused by a hormone (ecdysone) that is secreted from glands behind the brain. Organisms utilize high amount of energy while forming a new cuticle, and the old cuticle that is shed in this process is known as exuviae.

The answer is cocci.

There are three basic types of the shape of bacteria:
- Cocci - spheres,
- Bacilli - rods,
- Spirochetes - spirals.

If a student drew a circular shape, this probably represented sphere. Therefore, the shape of seen bacteria was spherical which suggests that the bacteria must be cocci.
