Answer:
The correct answer is C. differentiation.
Explanation:
Cell differentiation is a process via which generic embryonic cells are transformed into specialized cells through a process of gene expression. Certain signals from inside and outside our body initiates gene expression.
Cell differentiation occurs at various stages of development, which causes the size and the shape of the cell to change dramatically.
Importance of cell differentiation:
- Plays vital role in embryonic development
- Helps in developing organisms throughout their life
Answer:
The given situation is an example of the <u>Positive feedback loop</u><u>.</u>
Explanation:
Positive feedback is the phenomenon in which the effects of the small disturbances on a particular system can result in an increase in the perturbation magnitude. Positive feedback increases the input and causes instability in the system. Therefore, it refers to positive loop gain about closed loop of the cause and effect.
<u>Therefore, the given situation is an example of the </u><u>Positive feedback loop</u><u>. </u>
Answer:
People with the sickle cell mutation in both copies of the HBB gene produce proteins that clump together and lead to changes in the shape and behavior of red blood cells.
Answer:
Hi, There!
Denaturation Is the Correct Answer!
Explanation:
When an enzyme is denatured, it essentially melts and loses its shape. Denaturation can be caused by extreme heat and by changes in pH.

The answer is Regeneration of Neural Tissues
Axon regeneration has three phases: sprouting, elongation, and maturation (McQuarrie, 1983). As Schwann cells dedifferentiate and proliferate, the proximal stumps of the axons sprout by the actin-driven formation of growth cones (Sinicropi and McIlwain, 1987).
