Membrane lipids in tissue samples obtained from different parts of a reindeer’s leg have different fatty acid compositions. membrane lipids from tissue near the hooves contain a larger proportion of unsaturated fatty acids than those from tissue in the upper leg. what is the significance of this observation?

At lower temperature, membranes maintain fluidity by having a higher percentage of unsaturated fatty acids.

Explanation:

The fluidity of the membranes is affected by temperature. At lower temperature conditions, tight packing of saturated fatty acids makes the membranes more rigid. Therefore, membranes incorporate a higher proportion of unsaturated fatty acids to maintain the required fluidity. This is why the membrane lipids from the tissue near the hooves have a higher proportion of unsaturated fatty acids as the temperature of the tissues of a reindeer near extremities is lower than that of the tissues from the upper leg.

answer: - b cells

explanation: -

so, the b cells mediate their action by identifying the antigens present on the surface of the pathogens and then producing antibodies in return to mediate its effect.

burning fossil fouls really decrease the carbon in the atmosphere so b
