They absorb food from their environment and release ammonia into their environment through their body surface because their body is very flat, due to the lack of coelom
Hope this helped
A prediction in a controlled experiment allows researchers to form hypotheses and anticipate the results of an experiment. So your answer is D.
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.
Answer:
i think it is d. sorry if its wrong
