Darwin's theory of evolution is a result of scientific investigation. In this theory, they investigate by observing the distribution of species.
Answer:
The ocean produces oxygen through the plants (phytoplankton, kelp, and algal plankton) that live in it. These plants produce oxygen as a byproduct of photosynthesis, a process which converts carbon dioxide and sunlight into sugars the organism can use for energy.
Explanation:

The answer is
Let's first represent alleles:
R - a dominant allele for round seeds,
r - a recessive allele for wrinkled seeds,
Y - a dominant allele for yellow seeds,
<span>y - a recessive allele for green seeds.
</span>
The cross will look like this RRYY x rryy
So, all of the offspring will be heterozygotes (RrYy) with round seeds (Rr), yellow seeds (Yy).
I believe it is c because pcr steps are denaturation, annealing, and elongation. in which dentauring is when the temperature is raised in which our template dna strands seperate.
