Answer:
The sodium channel have refractory period.
Explanation:
Action potential are generated at axon hillock of neuron and travel across the neuron in response to stimuli. For the the generation of action potential the steps are stimulus, depolarization, repolarization, hyperpolarization and resting state.
So the first step for action potential after stimulus is depolarization. Depolarization requires the opening of sodium channels to make the inside of neuronal membrane positive. These sodium channels have refractory period. They cannot open immediately after activation. So the sodium channels of one direction in neuron (upstream) become refractory and it is convenent to open the sodium channels of other direction (downstream) of neuron. That why action potential is transmitted in one direction.
It is like the gunpowder placed at a line the fire cannot go back in burnt gun powder direction.
Answer:
Q = 813.12 j
Explanation:
Given data:
Mass of lead = 21 g
Initial temperature = 25°C
Final temperature = 327.5°C
Amount of heat absorbed by lead = ?
Solution:
Formula:
Q = m.c. ΔT
Q = amount of heat absorbed or released
m = mass of given substance
c = specific heat capacity of substance
ΔT = change in temperature
ΔT = T2 - T1
ΔT = 327.5°C - 25°C
ΔT = 302.5°C
Specific heat capacity of lead = 0.128 j/g.°C
Q = m.c. ΔT
Q = 21 g. 0.128 j/g.°C.302.5°C
Q = 813.12 j
Answer:
I think its cellular respiration
Explanation:
During cellular respiration, glucose is broken down while oxygen was broken down from water. Therefore, oxygen is present. So that means that it is most likely respiration.

The statement 'when paired with an immunosuppressant drug, saccharine (sugar) did not have immunosuppressant effects on rats' is FALSE. Saccharine is an artificial sweetener.
<h3>Immunosuppressant drugs and saccharine</h3>
Immunosuppressant drugs are a type of drug that exhibits a depressive effect o the immune system of the individual.
Immunosuppressant drugs include, for example, adalimumab, infliximab, calcineurin inhibitors, cyclosporine, etc.
Moreover, saccharin is an artificial sweetener that is 400 times as sweet as sucrose (sugar).
