A phospholipid is made of glycerol, two the fatty acid tails, and a phosphate-linked head group. More unsaturated fatty acids it means less tightly packed phospholipids its results to the greater membrane fluidity. Unsaturated fatty acids are naturally occurring, meaning that the remaining hydrogen is on the same side of the molecule and result in a bending of the hydrocarbon chain.
Answer:
So if the size of the pore is small then the rate of the diffusion will be very slow as the molecules will move from high concentration to low concentration in very slow rate.
Explanation:
I hope it helps you
Response would be correct, as in response to environment.
Answer:
Nitrogen thet cannot be used by organisms. C.
Explanation:
Free nitrogen is simply molecular nitrogen (N2). Nitrogen, in its molecular form, consists of two nitrogen atoms bound together with a tripple bond. Because it is very stable, N2 is typically nonreactive, and takes a lot of energy to break them apart. Among these are the amino acids necessary for life to begin and which are the building blocks DNA is made from. Basically, any nitrogen that is in an organic compound is considered “fixed” nitrogen and N2 is considered to be “free” nitrogen
