Osmosis is a natural phenomenon where molecules move from a lower concentration to a region with higher concentration. This occurs through water channel proteins called Aquaporins. This natural phenomenon can occur in cells which can cause shrinking or bursting.
Answer:
C. Nitrogen bases
Explanation:
It has an alternating chemical phosphate and sugar backbone, making the 'sides' of the ladder. (Deoxyribose is the name of the sugar found in the backbone of DNA.) In between the two sides of this sugar-phosphate backbone are four nitrogenous bases: adenine (A), thymine (T), cytosine (C), and guanine (G).
It will be transported into the cell through the process of endocytosis, which is a form of active transport. Active transport requires energy in the form of ATP. Hope this helps! :)
