<u>Answer</u>: c) bottleneck effect
<u>Explanation</u>: The significant reduction in genetic variation due to a major decrease in population's size for at least one generation is called a bottleneck effect. Although the population can recover, the low genetic variation will still pose a significant risk for the long term survival of the species.
Answer: Hydrogen bonds are created between the base pairs in DNA. Adenine pairs with thymine and cytosine pairs with guanine. Adenine and thymine create 2 hydrogen bonds while cytosine and guanine create 3. These bonds are fairly weak so that they can be broken when DNA is replicated (by an enzyme called helicase which unwinds DNA). However despite them being weak they do stabilize DNA's double helix structure as well.
Answer:
