Question

Which of the following statements are true? Select all correct answers.

• Cell membranes in reindeer legs (near the hooves) are kept flexible because they have a large number of saturated fatty acids.
• Cell membranes in cold-tolerant winter wheat plants have a higher ratio of unsaturated fatty acids to saturated fatty acids than do cold-intolerant wheat varieties.
• A plant that produces more monounsaturated fatty acids than polyunsaturated fatty acids in its membranes in winter has an increased resistance to freeze damage.
• Yeast cells that produce more unsaturated fatty acids than saturated fatty acids in response to cold have greater cold tolerance.

Answer 1

Answer:

Cell membranes in cold-tolerant winter wheat plants have a higher ratio of unsaturated fatty acids to saturated fatty acids than do cold-intolerant wheat varieties.

Yeast cells that produce more unsaturated fatty acids than saturated fatty acids in response to cold have greater cold tolerance.
