Answer:
Sexual competition often occurs within complex social environments where male displays can be received by potential mates, rivals, or both at once. In brown-headed cowbirds’ breeding flocks, for example, multiple males sometimes vie directly for a single female’s attention; at other times males have opportunities to sing to females without interference. It was tested whether cowbirds vary the intensity of their signalling across contexts like these. The songs were recorded from males courting females both with and without a male competitor in sight. The recordings were now played to solitary, naïve females in sound attenuation chambers, and also to a naïve aviary-housed flock. The songs males had produced when they could see their competitors were more attractive, eliciting more copulatory postures from naïve females and more approaches from birds in the flock.

Answer:
The presence of a larger proportion of unsaturated fatty acids in membranes imparts them fluidity at lower temperatures as required to maintain their normal functioning.
Explanation:
The proportion of unsaturated and saturated fatty acids in membranes regulates their fluidity. At lower temperatures, membranes become more rigid. To maintain their normal fluidity, the proportion of the unsaturated fatty acids in membranes is increased. The unsaturated fatty acids have double bonds in their hydrocarbon tails which in turn do not allow their tight packing and impart fluidity to the membrane core.
At higher temperatures, membranes become more fluid and therefore, the proportion of the unsaturated fatty acids is reduced. The tissues of reindeer at the body's extremities such as those near hooves are exposed to surroundings and thereby, lose heat and have lower temperatures. To maintain the fluidity of membranes, the cells of these tissues incorporate more of the unsaturated fatty acids in their membranes as compared to the tissues in the upper legs where the body temperature is relatively higher.
