Which of the statements are true? Cell membranes in cold tolerant winter wheat plants have a higher ratio of unsaturated fatty a

cids 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. Cell membranes in reindeer legs (near the hooves) are kept flexible because they have a large number of saturated fatty acids. Yeast cells that produce more unsaturated fatty acids than saturated fatty acids in response to cold have greater cold tolerance.

Answer:

Option-1 and 4

Explanation:

Fatty acids can be distinguished into two types: saturated and unsaturated fatty acids.

The saturated fatty acids are the fats that do not contain any double bond as a result of which they are tightly packed and are found in solid-state whereas unsaturated fatty acids are the acids that contain double bond in their structure and are found in liquid form.

The cold-tolerant species show an adaptation to survive in cold species by modifying their cell membrane composition that is they increase unsaturated fatty acids which help in maintaining the fluidity of the cell membrane.

Thus, in the given question option-1 and 4 show, this adaptation and are true options.

In detail what are the main differences in the 3 domains
DedPeter [7]

Answer:

Organisms can be classified into one of three domains based on differences in the sequences of nucleotides in the cell's ribosomal RNAs (rRNA), the cell's membrane lipid structure, and its sensitivity to antibiotics. The three domains are the Archaea, the Bacteria, and the Eukarya.
