vladimir1956 [14]

Answer:

M.P = 140.46 Vm

Explanation:

Membrane potential can calculated using the following equation:

<em>(61/z) ln ([X]out/[X]in)</em>

where z is the charge of Ca2+ ion and X represent the concentrations By applying necessary calculations…

Membrane potential = (61 / 2) ln (100 x 10^-3 / 1 x 10^-3)

                                  = 30.5 x 4.60 = 140.46 Vm

Protozoans are the only organisms that can convert nitrogen from the air into chemical compounds that plants can use.
tigry1 [53]

Answer: False

Explanation:

Protozoans are not the organism that fix nitrogen for the plants. The organism that fix nitrogen to convert it into a form which can be used by plants are known as diazotrophs.

These are bacteria and archae that fix nitrogen gas found in the atmosphere into more usable form such as ammonia.

These organism can grow without any external source of fixed nitrogen. Example: Rhizobia and azospirillium.

Why does blood pressure in both arms differ
Alika [10]

Explanation:

Generally, a small difference in blood pressure readings between arms isn't a health concern. However, a difference of more than 10 millimeters of mercury (mm Hg) for either your top number (systolic pressure) or bottom number (diastolic) may be a sign of blocked arteries in the arms, diabetes or other health problem

.A significant difference in the pressure recorded in the right and left arms can signal circulatory problems that may lead to stroke, peripheral artery disease, or other cardiovascular problems.
