Identify the steps of the phosphorus cycle?

1 answer:

3 0

Over time, rain and weathering causes rocks to release phosphate ions and other materials. This inorganic phosphate is then distributed into the soil and water. plants take up inorganic phosphate from the soil. the plants may then be consumed by animals. Once in the plants or animal, the phosphate is incorporated into organic materials that break down organic matter to inorganic forms of phosphate. this process is known as mineralisation. Phosphate in soil can end up in waterways and eventually oceans. once there, It can be incorporated into sediments over time.

Suppose molecules were unable to diffuse into and out of the cells. How might life be different if cells had to use active trans

antiseptic1488 [7]

Answer:

Cells would most probably not exist because these units of life metabolize energy molecules like glucose to harness their energy for the running of biochemical processes, like active transport, to support life. However, harnessing this energy from these energy molecules is NOT 100 percent efficient. A higher percentage of energy is lost as heat in the process.

Therefore if the cells were required to carry all molecules in and out of the cell, actively, including the energy molecules themselves (which is counterintuitive), this would require a lot of energy and would be unsustainable. This would be analogical to the counteracting and infinite loop of more fuel needed to carry the mass of the more fuel in space travel...

Priya has been having trouble conceiving. She went through testing at a fertility clinic and found that everything seemed fine w

NARA [144]

Answer:

A. Estradiol

Explanation:

Estradiol, which is also referred to as 17 beta-estradiol, is an estrogen steroid hormone. This form of estrogen is one of the major female sex hormone that plays major role in the female reproductive system such as regulation of the estrous and menstrual cycle. It also helps in regulating body metabolism.

Reduction in the level of Estradiol is one of the problems common in women approaching menopause. Optimal level of estradiol in the body helps improve fertility in the body as symptoms such as such as vaginal dryness, burning, itching that are associated with menopause are reduced to the barest minimum.

The supplement taken by Priya in order to thin the mucus and allow sperm to get through the mucus to the uterus most likely works to benefit the body by increasing <em>estradiol.</em>

A 5' cap is not added to ribosomal RNAs or transfer RNAs because they Group of answer choices do not contain any guanine. are no

Svet_ta [14]

Answer:

do not bind the small ribosomal subunit.

Explanation:

5' CAP is a structure present only in the mRNA molecule. It is characterized as a "helmet" added to the 5' end of the mRNA molecule.

The main function of 5' CAP is to protect mRNA in the cytoplasm (when it leaves the nucleus towards the ribosome). This is because in the cytoplasm can be found the enzymes ribonucleases and fostases that can alter the function of proteins that allow the mRNA to bind to the smaller subunit of the ribosome.

Since tRNA and rRNA do not need to be linked to the ribosome, they do not need the presence of 5' CAP in their compositions.
