<span>ne day, while walking through a crowded zoo, I noticed that suddenly there were no people walking on the path anymore. I happened to be next to the gorilla den, which was just a cul-de-sac at the end of a long, curved trail. I thought I'd go in since I was there. </span>
The correct answer is C. It is a sudden change that causes species to become extinct.
This answer is not correct because evolution occurs over a long period of time, as evidenced by the theories that describe its timeline (including gradualism and punctuated equilibrium). Additionally, evolution does not always involve the extinction of a species, but it can.
Hope this helps!
Answer:
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.
