A receptor refers to a protein molecule, which attains chemical signals from external of a cell. The receptor proteins are categorized by their location. On the other hand, the structural proteins refer to the fibrous proteins. One of the essential activity of the structural protein is to maintain the configuration of the cell.
In the nerve cells, the receptor proteins pick up signals of pain and structural proteins helps in maintaining the shape and configuration of the nerve cell.
Answer:
Yes, dynamic equilibrium is present in the cell.
Explanation:
In dynamic equilibrium, the concentration of solute remain the same due to equal flowing of solutes inside and outside the cell so there is no change occurs inside the cell, the cell maintain same concentration of solutes both inside and outside the cell. Dynamic equilibrium is a type of equilibrium in which the reactants and products formed at the same rate and no change occurs inside the reaction. In the cell, homeostasis is responsible for maintaining equilibrium in the cell so no change occurs inside the cell.
Answer: option C.
A commonly accepted set of scientific ideas or assumptions.
Explanation:
A paradigm is a set of ideas or assumptions, thought patterns or concept that scientist use to describe a legitimate field. The purpose is to provide the audience with illustrations about some occurrences which will help to guide them.
Answer:True
Explanation:
Nerve impulse must reach a certain threshold in a neuron before action potential can be generated to intiate conduction of action potential.
Therefore if mutiple impulses are generated and these are not upto thresholds , no matter how strong the stimulI are-NO ACTION POTENTIAL WILL BE GENERATED.
THIS IS ALL OR NONE PRINCIPLE
The all or none hypotheses can be best explain with flushing of the water closet after using it. If required volume of water is not pumped into the water closet storage above, no matter how long the handle is push, FLUSHING WILL NOT TAKE PLACE.Thus the threshold volume of water must be met.
Answer:
After several hours, both beakers are expected to have the same temperature of 65°C
Explanation:
Given that:
The temperature in beaker A = 80°C
The temperature in beaker B = 50°C
The copper rod used to connect allows transference to heat and temperature from beaker A to the beaker B because it is a good conductor of heat and electricity. After several hours, movement of heat and the temperature have occurred and they have both reached equilibrium.
Therefore, after several hours, both beakers are expected to have the same temperature of 65°C
i.e.
= ((80 + 50)/2) °C
= (130/2)°C
= 65 °C
