In a resting potential, an example of a cation that is more abundant as a solute inside a neuron than it is in the interstitial fluid outside the neuron is
a. cl
b. k
c. hco₃
d. na
e. ca

B) k

Explanation:

potassium is an intracellular cation.

In resting state its  gated channels are  shut; so  95% are trapped inside the interstitial fluids of the axoplasm;Although these channels leak for some to escape  down the concentration gradient to the extracellular environments  of the axon, most of these ion are concentrated inside the interstitial fluid of the axon to maintain RMP

eukarya because is is like alche and b is bacteria and d is animals

explanation:

the correct answer is: b. pantala flavescens, because these organisms would have a high level of genetic variation due to sexual reproduction.  

because involves two organisms (parents) whose genetic material combines, sexual reproduction leads to genetic variation in new generations of offspring. the offspring is an unique organism, with new genome, more protected with the higher ability to adapted. this process is fundamental to evolution.
