Would you expect an amoeba that lives in a pond in a cold northern climate to have a higher or lower percentage of saturated fatty acids in its membrane during the summer as compared to the winter?

During the summer, an amoeba living in a cold northern climate would likely have a lower percentage of saturated fatty acids in its membrane compared to the winter. In warmer temperatures, the organism may incorporate more unsaturated fatty acids into its membrane to maintain fluidity and function. Conversely, in colder temperatures, a higher percentage of saturated fatty acids would help to stabilize the membrane and prevent it from becoming too rigid.
