The correct answer is letter A, the increased nitrates from the fertilizers leech into the water and cause algal blooms, which take oxygen out of the water and this suffocates fish.
This is one of the many chain reactions that agricultural farming brings to the environment, and it will be very common through the years as people have not figured out a safer way to protect crops.
<h2>Answer:</h2>
When the crossing over results in both mutant alleles on one chromosome and the other chromosome will be mutation free.
<h3>Explanation:</h3>
During the meiosis chromosomes are present in homologous form in a pair.
They exchange their genetic material with each other. This exchange is random and usually genetic material on the ends/telomere changes with the homologous chromosome.
In given condition the exchange is in such manner that the mutant allel of one chromosome shifts to other during crossing over. While other chromosome also contains its own mutant allele and does not exchange it during crossing over.
If the forces are unequal and acting in different directions, you subtract the smaller number from the bigger number. Forvexample, 5 newtons-3 newtons=2 newtons. The object moves in the direction the bigger number is pointing.
