In eurkaryotes, the wrapping of DNA around nucleosome introduces negative supercoiling because negative super coil knots have high twisting stress and are less tightly packed.The combine loop of protein [histone] and chromosome is called nucleosome.
Answer:
True statement.
Explanation:
Climate change is the shift or abnormal change in climate patterns. As the planet warms quickly, mostly due to human activity, climate patterns in regions around the world will fluctuate. Ecosystems and biodiversity will be forced to fluctuate along with the regional climate, and that could harm many species.

Answer:
C) The smaller population will be more affected than will the larger population, because the smaller population has less genetic variation than the larger population has.
Explanation:
Genetic variations are present in the natural populations. Some of the genetic traits become adaptive under the changed environmental conditions and allow the individuals carrying them to survive and reproduce. In this way, the genetic variations help to maintain a population.
Therefore, a larger population of a squirrel species with more genetic variations will have less intense impacts of a disturbance/natural calamity and/disease. On the other hand, a smaller population of the same species with a lesser number of squirrels has fewer genetic variations. This population is more likely to be affected in a negative way by a disturbance such as pathogen.
