22) Phosphorus and sulfur are returned to the soil primarily by the actions of
Fudgin [204]
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.

How do researchers prepare an intron-free copy of a eukaryotic gene for use in creating transgenic bacteria?
Tcecarenko [31]

The researchers prepare an intron-free copy of the eukaryotic gene for the use in creating the transgenic bacteria by using the reverse transcriptase to make the cDNA from the mature mRNA

The structure of the eukaryotic genes. Most of the eukaryotic genes are contain the segments of the coding sequences (exons) that interrupted by the noncoding sequences (introns). Both the exons and the introns are transcribed to yield a long and primary RNA transcript.

Eukaryotic DNA is the linear, compacted into the chromosomes by the histones, and has the telomeres at each end to protect from the deterioration. The Prokaryotes contain the circular DNA in addition to the smaller, transferable DNA plasmids. Eukaryotic cells contain the mitochondrial DNA in the addition to the nuclear DNA

The answer is A38.9.

The code for scarlet fever is A38.9.

What is scarlet fever?

Some patients with strep throat go on to acquire the bacterial disease known as scarlet fever.

In-s [12.5K]

Answer: etiolation of plant growth in shade, with fast growing cell without chloroplasts. Out of shade, cell differentiate again to produce photosynthesising cells

Explanation: It is a subjective decision as to what is ‘best’. Good examples are plant responses to changes in the nutrient supply.

when soil nitrogen is depleted some plants, such as legumes, grow nodules on their roots, with cells that release chemical signals to attract nitogen fixing bacteria.

Lack of light induces etiolation in many plants. New cells elongate and develop without chloroplasts, with rapid cell division exhibiting gravitropism, extending upward. When they grow beyond the shade area, cell differentiation changes again, to produce photosynthesising cells.
