Answer:

Generally, K+ ions ensures re-polarization of  the membrane potential. It always ensures that the neuron returns its resting  state, protecting the  neurons and ensuring episode of rest before the next action potential.

K+ does this by leaving the axon, making the inner layer more negative. This is resting membrane potential. Because there are many K+ channels for leakages out of the neuronal axons.

Therefore, in this scenario, he neuron will return to its resting membrane potential state which between values -50 to -75mV.

Therefore the value of the potential will be -60mV, or within the range of -50 to -60mV. This is because the neuron is is non- excitable.

Alja [10]

Variations can be genetic or environmental, the traits are passed from one generation to other generation of snail is from from both parents to offspring and through the environment.

The correct answer is C.

Explanation:

Genetic variation in an organism is passed to the offspring by its parents.

environmental variation is the the result of different environment with which individual adapt.

Natural selection is a process in which a suitable trait which is well adapted to the environment is passed on tho future generations.

Genetic variation is the change in DNA or gene of the individual trait. The tree snails having different pattern in their shells is due to the habitat they are living in.

The snails which have well adapted to the environment are able to reproduce and pass on the traits to their progeny. The variation is due to the traits passed from parents through the environment also.
