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
The correct answer would be that substance A is rice, and substance B is sugar.
For substance A to be filtered out, it means that A is a water-insoluble substance and for substance B to be recoverable by evaporating off the water, it means that B is water-soluble.
Thus, A can neither be sugar nor alcohol because neither can be recovered by filtration. Also, B can neither be coffee nor alcohol because they can not be recovered as residue through evaporation of water.
Therefore, the only correct answer is that substance A is rice, and substance B is sugar because rice can be filtered out from water while the water-soluble sugar can be recovered by evaporating the water.

Wetlands DO NOT increase the rate of extinction of mammals by creating a loss of habitat. Wetlands rather form a habitat for many organisms creating a rich microcosm of an ecosystem.
Explanation:
Wetlands are land areas that are seasonally or permanently submerged in water. They include marshlands, estuaries, deltas, swamps, floodplains, and etcetera. The plants within wetlands, such as mangrove slow down water runoff hence allowing settling down of, sediments and pollutants hence ‘cleaning’ the water.
Due to this fact that wetlands slow water movement, these ecosystems are significant in reducing flooding by ‘storing’ flood water and releasing it slowly hence acting like flood controls.

Answer: c Blue whale
Explanation:omnivore is
an animal or person that eats food of both plant and animal origin.
Blue Whale is a carnivorous animal that despite the fact that it doesn't have proper teeth, survives on a diet that is mainly comprised of krill and small crustaceans, along with the occasional small fish.
