Answer:
(a) an aquaporin
Explanation:
An aquaporin is a water channel which forms a pore in the cell membrane and facilitates the movement of water. Aquaporin is an integral membrane protein (permanently attached to the membrane) that enables the in and out flow of the water. This channel also prevents the passage of ions and other solutes, so it cannot change the voltage. There are four types of aquaporins, and they are mostly found in the kidney with the function of water reabsorption.
Answer: Hydrophobic
Explanation:
Think about how water reacts with oil. When you mix the two the oil would stay in little drops within the water so they are not mixing. The tails of the membrane prevent water from leaking out by sticking together and not letting water through. Just to solidify this Phobia= fear, lipids are water "fearing".
Egg whites are separated out before pasteurization.
First, the eggs are washed and candled. They are then broken
and yolks and egg whites are separated. The liquid eggs run through a filter to
make sure there are no more egg shells. The liquid egg whites the pass through
pipes heated at temperatures that can kill the microorganisms without cooking
it. It is then cooled and packaged for use
Answer:
Your answer is D) Graduated Cylinder.
Answer:
The correct answer is D) the vacuoles can "come and go" across the plasma membrane.
Explanation:
The endosymbiotic theory exposes that mitochondria and chloroplasts were "swallowed" several years ago by a prokaryotic cell, that then became eukaryotic. These two organelles were originally two living and independent organisms, that's why the have their own DNA and also divide splitting. Anyway, the endosymbiotic theory does not explain anything about vacuoles and also, the sentence is not true. No organelle can come and go across the membrane, it's impossible for an organelle to break such barrier.
