your answer is:
B. The angle of the slope.
Cellular Respiration and Photosynthesis<span> are </span>almost opposite processes<span> because </span>photosynthesis<span> removes carbon dioxide from the atmosphere while </span>cellular respiration<span> puts back carbon dioxide. </span>Cellular respiration<span> uses oxygen and has its waste product of carbon dioxide (CO2).</span>
Enzymes are (usually) specific to the substrates they bind to. Thus, each enzyme has one and only one substrate structure they can metabolize, so even substrates with similar structures cannot be broken down by an enzyme specific to one of them.
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>
