Stimulus stimulate the sodium ion voltage gated channel to open in the axon. This allow many Na ion to enter the axon and causes depolarisation as the pd in the axon getting less negative charge (from -70mV to -50mV).
Answer:
The experiment should have more different subject groups, with each group consuming a different amount of beta carotene.
Explanation:
When designing an experiment, to determine the effect of the amount of a substance, the experimental design should be done to accommodate more than two experimental group with each group treated with different amount of the substance and also a control group. This will enable the researcher to determine the effect of the different ranges of amount.
In the example, in other to determine if vitamin A is dependent of the amount of beta carotene consumed, there should be more different subject groups, with each group consuming a different amount of beta carotene.
Answer:
the answer is Newton's third and Second law
Explanation:
Newton's second law tells us that the force that is generated on a body is proportional to the acceleration it acquires.
F= M*A
at lower mass greater acceleration
Newton's third law explains that for each force that acts on a body, it performs a force of equal intensity and direction but in the opposite direction to the body than gender.
