Answer:
B. Cells in Alex’s body underwent mitosis to create new tissue
Explanation:
Mitosis is the cell division that forms two genetically identical daughter cells from one parent cell. It occurs in somatic cells and is responsible for the growth and development of individuals.
Alex gained the height as the cells in tissues of his body underwent the mitosis and produced new daughter cells. Repeated cycles of mitosis added a large number of new cells to his body to form new tissues in his body parts and caused an increase in his height.
Answer:
d. carries nerve impulses toward another neuron, a muscle fiber, or a gland cell
Explanation:
An axon is a fiber of the nerves that transmits nerve impulses( electrical signals) away from a cell body and towards another neuron, muscle fiber or gland cell.
We have two types of axons in the body.
a. Myelinated axons
b. Unmyelinated axons.
The difference between Myelinated axons and Unmyelinated axons is that the Myelinated axons has an external covering or insulation which is called the myelin sheath.
The myelinated axons are very numerous and mush faster than the unmyelinated axon.
Answer:
A) Surface-active agents, or surfactants, decrease surface tension among molecules of a liquid.
B) Phenolics exert antimicrobial activity by injuring lipid-containing plasma membranes, which causes the cellular components to leak out of the cell.
C) Alcohols exert their action by denaturing proteins and dissolving lipids.
Explanation:
Explanation:
<em>Food webs and the carbon cycle are very closely related because every living organism is made up of carbon. ... When a person eats the cow, the person consumes carbon. Thus, carbon moves through food webs. It leaves living organisms through respiration and when organisms die and decompose.</em>
