Answer:
a. It has a negative value.
b. It is measured in millivolts.
c. It is measured in millivolts.
Explanation:
Resting membrane potential is typically ~ -70 millivolts so options a, b and c are correct, rest are false statements.
The resting membrane potential is -70 millivolts because more K+ is inside the neuron while more Na+ is outside the neuron and it reflects more negative voltage in the cytosol as compared to the interstitial fluid.
As soon as stimulus arrives, it causes more Na+ to move inside the neuron making the membrane potential as +20 millivolts and the neuron is said to be in 'depolarized state'. Soon after that K+ starts to move outside of the neuron and since K+ has positive charge and it is moving out of the cell so the membrane becomes more and more negative inside and at this time neuron is said to be in 'hyperpolarised state'.
The correct response is complement. It do not have a function or role in both the innate and adaptive immune system.
Adaptive immune responses have the purpose of eliminating invasive infections and any hazardous chemicals they may create. It is essential that these responses are only created in response to molecules that are foreign to the host and not the molecules of the host itself because they are damaging. Innate immunity, also known as nonspecific immunity, is the defense mechanism you were born with. You are shielded from all antigens by it. Barriers that prevent hazardous substances from entering your body are a part of innate immunity. These barriers serve as the immune system's first line of defense.

You can confidently conclude that the concentration of the unknown solution is less than 100ppm. Because the concentration of the liquid in the beaker is higher than that of the unknown solution that is why water move out of the dialysis bag into the beaker of water. Thus, the solution inside the beaker is an hypertonic solution, that is why it deflated the dialysis bag.
Because we control them both in the same direction so if we where like some lizards that move each eye individually then we would see two images
