Answer:
d
Explanation:
The use of fertilizers is the leading cause of eutrophication. The use of fertilizers, especially nitrate and phosphate fertilizers on farms, lawns, and golf courses, result in the accumulation of phosphate and nitrate in the nearby water body sources
would be the second part, plants.
energy (sun) -> producers -> consumers -> decomposers
Genetic variation can be caused by mutation (which can create entirely new alleles in a population), random mating, random fertilization, and recombination between homologous chromosomes during meiosis (which reshuffles alleles within an organism's offspring).
which class question is this?
Answer:
D
Explanation:
<u>Sister chromatids</u> will have the same form of alleles at the locus after S phase.
<em>This is because during the S phae of the cell cycle, sister chromatids are replicated in preparation for cell division. The replication process is quite accurate such that all the alleles present on the initial chromatids are also replicated on the new sister chromatids. Hence, both new and old chromatids will have the same form of alleles at the locus after replication at the S phase. In other words, sister chromatids are exact copy of one another.</em>
The correct option is D.
