Answer:
A. Parasitism, because the flee is benefitting and the mammal is harmed.
Explanation:
Parasitism is when one organism which is a parasite lives on another which is the host, and gaining benefits from it and at the same time maiming havoc to it. Parasitism is common among living organisms. Animals are most times the host to a range of parasitic organisms which include viruses, bacteria, fungi,protozoa, also flea, tick, mites etc.
Parasites like fleas, tick and leeches live on the body surface of their host, which is make them ectoparasites while those that live inside their hosts are endoparasites.
Eukaryotic organisms contain translocation factors that are suited to perform the same function. A translocation that results in Tu being replaced with G or G being replaced with Tu will not affect the function of the protein.
c. water
water is nonliving, algae is a bacteria which is alive. a minnow is a type fish; alive. a turtle is alive.
The phospholipid bilayer functions mainly as a structural framework for the membrane where the polar heads of the phospholipids tend to orient towards their polar surroundings, preserving the hydrophobic part from any contact with water.
<h3>What are phospholipids?</h3>
They are lipid molecules that have a strongly polar group in addition to the hydrophobic hydrocarbon chain.
<h3>Characteristics of phospholipids</h3>
- The polar heads are oriented towards the aqueous medium (intra and extracellular).
- The hydrophobic tails tend to be oriented towards the lipid medium, that is, inside the bilayer, constituting the membrane matrix.
Therefore, we can conclude that phospholipids, due to their amphipathic nature, tend to orient or organize themselves spontaneously, forming the so-called lipid bilayer.
