Answer:
The correct answer is option B.
Explanation:
The ciliates are a group of the organism of protozoans characterized by the presence of cilia, a hair-like structure, that appears to be the same as the eukaryotic flagella.
These organisms are shorter in size and found in high numbers. They normally have more than one nuclei so known as multinucleate. They found in the freshwater.
Thus, the correct answer is option B.
reduce lipid mobility
decrease membrane fluidity
When fatty acid tails are saturated, it means that their conformation is perfectly straight becoming easy to compact more and more fatty acids, as they fit perfectly together, and therefore reducing lipid mobility. In turn, if lipid mobility is reduced, the membrane fluidity is decreased because the lipids are too "stiff" together.
