Answer:
a: metaphase
Explanation:
the chromosomes are aligned at the metaphase plate
The genotypes of the parents are Aa (heterozygous) and aa (recessive homozygous).
For example:
If the purple flower is dominant phenotype, then A is a dominant allele for it and Aa is a genotype which will give the purple colour.
In this case, white flower is recessive phenotype with aa genotype.
If we cross Aa x aa
<span>The offspring is going to be Aa Aa aa aa (half purple and half white)</span>
B. By lowering the energy need for the reaction, you increase the reaction speed or the rate.
