A,C,D are the answers. I took Biology.
THe bacteria that lives in the nodules of legumes are the only ones able to fix nitrogen gas into ammonia, which is later fixed by other bacteria in the soil to nitrites and nitrates that the plants can use.
some bacteria also performs denitrification, which converts ammonia back to nitrogen gas, allowing the cycle to continue
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).
