Answer:
The binding of a neurotransmitter on a postsynaptic cell allows potassium ions to diffuse out of the cell. This would result in a NEGATIVE CELL MEMBRANE POTENTIAL which is an HYPERPOLARIZATION event.
Explanation:
The binding of a neurotransmitter to a postsynaptic cell results in a group of channels in the cell membrane called ligand gated channels open or close in response to that binding.
Hyperpolarization occurs when a ligand gated channel opens and allows potassium ion to flow out of the cell.
During hyperpolarization, potential of the cell membrane experience changes which makes it to become more negative.
Answer:
stay the same, decrease, increase in that order
Answer:
Both store materials needed by the organism.
Explanation:
Proteins and carbohydrates are two biomolecules present in living organisms. They perform varying functions in the body of an organism. According to this question, a specific protein (ferritin) and carbohydrate (glycogen) is described.
Ferritin is a protein molecule containing Iron (Fe). Iron is needed by living organisms as it plays a vital role in organism's metabolism. On the other hand, glycogen is a carbohydrate molecule that is made up of glucose molecules, needed by living organisms.
Based on the description of the two biomolecules provided, they are similar in their primary functions for an organism in the sense that THEY BOTH STORE MATERIALS (glucose and iron) NEEDED BY AN ORGANISM.
Answer:
cell
tissue
organ
system
human organism
Explanation:
unicellular organisms only have one cell since two or more cells form a tissue their level of organization is restricted to cell
cell
two or more cells form a tissue
two or more tissue forms an organ
two or more organs form a system which must work in coordination for efficiency
two or more systems make up a human organism
