The physiological concentration of monovalent salt ions (primarily sodium, potassium, and chloride) in the human body is on the order of 0.15 molar (0.15 moles per liter or 150 moles per meter cubed). Let's assume that ions only within one nanometer (1x10-9 m) of the membrane cell wall participate in creating the resting and action potentials, which is also a few hundredths of a volt but with opposite polarity (during a pulse the potential outside the axon is temporarily smaller than the potential inside the axon). Considering your answer to the previous problem: a. Are very many of the ions transferred across the member to change the potential during a nerve pulse?
b. And what does this tell us about the change in concentration of the salt ions near the cell wall with respect to physiological concentrations?

hey bro i looked it up on google the structure of the eye-spot in euglena viridie, e. ehrenbergii, and phacus pyriyorme is not as franzé haa described it. the so-called “crystal body” and “lens bodies” were not found in any of the individuals of the species examined by me. as earlier observers have stated, the eye-spot consists simply of a mass of pigment granules arranged in a single layer, and probably embedded in a protoplasmic framework, but the latter could not be seen, and its presence was only inferred from the fact that the pigment granules must be held together in some way, thd the eye-spot as a whole is capable of expansion, and that the pigment granules can be separated from each other.

hope this   and an i get brainlsiest

i believe the answer would be b. hope it : )

request for reexamination

yes, because even though a theory has a  lot of evidence to support it, it is not always true
