I believe the answer is decomposers. Does that make sense in the context of what you have learned in class? If you look up "the circle of phosphorous," you can see images that show that decomposers, like fungi and microbes break down dead animals and plants using some of their phosphorous, but what isn't used is returned to the soil. The same can be said for sulfur. Decomposers like fungi and bacteria break down dead plants and animals and return sulfur to the soil.
I want to warn you that there is a slight possibility that I might be incorrect. I am still pretty sure I am right. The only thing that makes me question the correctness of my answer is another brainily question I saw when i was looking up this stuff. Two people had responded to that Middle schoolers question and had said the answer was producers. They didn't give any explanation for their answers. So, I am confused as to how they both got the same answer that was different from mine. No material that I have seen regarding either the phosphorous cycle or sulfur cycle has shown plants as RETURNING the most sulfur and phosphorous into the soil. Usually, it has been depicted that producers, such as plants, UTILIZE the most phosphorous and Sulfur from the soil.
The health of people damaged when the mercury is released into the atmosphere because of its toxic nature.
<h3>
What is the effect of mercury?</h3>
Mercury contamination is a great threat to public health and environmental because methylmercury easily enters the bloodstream which leads to damaged brain. It is considered toxic for the humans due to its damaging nature.
So we can conclude that the health of people damaged when the mercury is released into the atmosphere.

After hundreds or even thousands of generations both alleles for sickle cell anemia are still common in those of African ancestry. This is supported by two mechanisms: heterozygote advantage and gene flow.
Heterozygote advantage
When an allele is said to be heterozygous, it is carrying one copy of a gene. For example if one carries a copy of sickle cell allele, it will stay in the population even after many generations — natural selection will not be able to remove it and it will be passed on through generations. So, having one copy of that allele is advantageous but not deleterious.
Gene flow
With humans migrating throughout the different parts of the world, sickle cell allele is passed from one person to another or in different populations. It is actually advantageous to have one copy of this allele especially if there’s malaria in the area, which the allele is resistant.
Answer:
b. such as RNA and DNA
Explanation:
DNA and RNA represent essential molecules present in all organisms. These nucleic acids (DNA and RNA) are composed of large chains of nucleotides that function to synthesize proteins required for cellular processes and to produce cell structures. Both RNA and DNA are highly stable biomolecules capable of storing and transmitting genetic information, which has been a requisite for the evolution of modern cells. Moreover, it is important to note that DNA is a double-stranded molecule and therefore it is more stable than single-stranded RNA.
