Explanation / Answer

Ans: The length of the fatty acids chain decreases and the saturation of the fatty acids is increased.

Lipid molecules in the bilayer normally have a mobility, thus behaving as a flexible liquid rather than a solid. A fall in environmental fall can decrease this mobility and decrease the vital activitiess of the cell.

Studies have shown that the organism Thermomicrobium roseum, in which long-chain diols and fatty acids showed increased branching as growth temperature was reduced from 75°C to 60°C; there was also a small increase in chain length. The general response of all micro-organisms to reduced temperature is to synthesize lipids with lower melting points. This may be achieved by unsaturation, branching, cyclization and chain shortening.

Here as the snake moves from the cold to warm condition, the chain length of fatty acids decreases and the saturation increases.
