Answer:
B. Each allele must be equally beneficial.
Explanation:
There are five main requirements to achieve Hardy-Weinberg equilibrium:
- No mutation
- No migration or gene flow
- Very large population
- Random mating
- No natural selection
The red-purple allele difference has to do with #5, <u>no natural selection.</u> This difference in alleles "Therefore, more of them will survive and reproduce" indicates natural selection, and hence evolution, may occur, which cannot happen in Hardy-Weinberg.
Answer:
At sea level, air pressure is greatest because it is caused by the weight of the entire column of atmosphere at that altitude over that location. As altitude increases, the column of atmosphere gets shorter, and so less weight is pressing down at a given altitude, so atmospheric pressure is reduced.
DNA has to be divided into the two nucleotide chains that build it, so that new chains can be started to form. These new chains will connect with the old ones.
