The answer is; active transport
This means that energy is expended in the process. Because large protein cannot be transported through protein channels in the plasma membrane for being too big, they are transported through endocytosis. This means a vesicle merges with the plasma membrane and forms an invagination that engulfs the protein. The vesicle then encloses with the protein inside and moves into the cell.
Answer:
NH4+
Explanation:
A Lewis base is a substance with the ability to share or give pairs of electrons.
The NH4 + ammonium ion donates a proton, therefore the ammonium ion is a Lewis acid.
<span>Answer:
Connect the atoms with single bonds. The less electronegative is the phosphorous atom. Hence, the P atom is going to be the central atom. Recall that electronegativity decreases as we move away from the fluorine atom in the periodic chart.

A high concentration of water has <u>fewer</u> dissolved particles than a low water concentration.
Most cell membranes are not as easily permeable to many dissolved compounds as water is. There is a quick and constant flow of water. From one area with less dissolved matter to another with more, water transports NET. Or, if you want, from an area with a lot of water to one with little water. The terms isotonic, hypotonic, and hypertonic refer to the concentration of dissolved material. In a medium, such as the extracellular fluid, every distinct material has a concentration gradient that is unique from the gradients of other substances. Every substance will diffuse in line with that gradient as well.
