Paramecium Is a Unicellular Organism That Lives in Fresh Water

Multiple Choice

Paramecium is a unicellular organism that lives in fresh water. Suppose you are studying two populations of this organism: one population lives in a pond in northern Ontario, Canada, and the other lives in a pond in southern Florida. If you examined the plasma membranes of both of these populations at the same time of year, what difference would you expect to find between the two populations' cell membranes?

A) The fatty acid side chains in the membrane phospholipids of the Florida Paramecia would generally be longer and would be more saturated compared to those in the membranes of the Canada Paramecia.
B) The fatty acid side chains in the membrane phospholipids of the Florida Paramecia would generally be shorter and would be more saturated compared to those in the membranes of the Canada Paramecia.
C) The fatty acid side chains in the membrane phospholipids of the Florida Paramecia would generally be longer and would be less saturated compared to those in the membranes of the Canada Paramecia.
D) The fatty acid side chains in the membrane phospholipids of the Florida Paramecia would generally be shorter and would be less saturated compared to those in the membranes of the Canada Paramecia.
