Answer:
Option-C
Explanation:
The phospholipids are the major constituents of the cell membrane of a cell. The phospholipids contains the glycerol attached to the phosphate group and forms the hydrophilic heads whereas the fatty acid tails from the hydrophobic portion of the membrane.
The hydrophobic head face outwards whereas the tails face inwards. The structure of the membrane as arranged in bi lipid layer form and in such a way that the membrane molecules can move. The other molecules present in the membrane like the proteins can drift in the membrane.
Thus, Option-C is correct.
Explanation:
Cell membranes are selectively permeable. Some solutes cross the membrane freely, some cross with assistance, and others do not cross at all. A few lipophilic substances move freely across the cell membrane by passive diffusion. ... Large molecules do not cross intact cell membranes, except in certain special cases.
Carbon dating is a process that estimates the age of anything. However, there are flaws that exist. It may not be a precise number, but it does gives a good estimation.
Answer:
Most likely centripetal force. Newton's first law states that an object in motion will continue to remain in motion unless acted upon by an outside force. In this case, that outside force is the centripetal force.
