Answer: C. DNA or (Deoxyribonucleic acid )
Explanation: Deoxyribonucleic acid (DNA) has a unique role as the genetic material, which in eukaryotic cells is located in the nucleus.
Answer:
C) genetic drift.
Explanation:
Genetic drift is the random change in the frequency of alleles in a population due to random sampling. Many circumstances can lead to genetic drift for example bottleneck effect, founder effect, etc.
The bottleneck effect occurs when most of the members of a population die because of any natural disaster like flood, fire, etc. This can cause a certain allele to be lost in the remaining population because of losing major populations. So here due to hurricane half of the mammal population gets eliminated which shows it is an example of the genetic drift.
The answer is C) Two. Dipolar means there are two magnetic poles charging with the same magnitude but opposite polarity.
Explanation:
Variations in the sun's energy reaching Earth
Changes in the reflectivity of Earth’s atmosphere and surface
Changes in the greenhouse effect, which affects the amount of heat retained by Earth’s atmosphere
