Answer:
to grow the maize plant take nitrate ion (it is essential for the growth of the plant [maize] to grow it takes the nitrate ion basically nitrogen from the soil)
En la célula eucariota el ADN está rodeado por una membrana constituyendo el núcleo. El citoplasma es muy variado y rico en orgánulos celulares diferentes. ... Es una capa compuesta por proteínas y fosfolípidos cuya función es separar el interior del exterior celular e intercambiar sustancias.
Explanation:
<h2>Answer:</h2>
The same type of amino acid, means acidic amino acid substitution will leads to normal folding.
The amino acid will be glutamic acid.
<h3>Explanation:</h3>
- Sometimes the amino acids of the same type substitution leads to normal proteins.
- As the acidic group of aspartic acid is responsible for the folding of the protein .
- So if the amino acid is substituted by glutamic acid, it will not leads to any abnormal protein folding.
- Because glutamic acid also has a acidic group which is responsible for folding of protein.

Explanation:
Cyclins are proteins that regulate the progression through the cell cycle, i.e., the transition of G1 to S phase. It is well known that high cyclin expression may lead to cell proliferation states, which is closely associated with cancer progression. Moreover, the blockage of cyclins may have an anti-carcinogenic effect by inhibiting the progression through the cell cycle. MAP kinases are serine/threonine kinases that regulate the progression through the cell cycle by phosphorylating a variety of substrates during cell proliferation. In consequence, phosphatases that inactivate MAPK kinases (i.e., by dephosphorylation) may have an anticarcinogenic effect. The p53 is a tumor suppressor protein involved in diverse cellular processes including DNA repair, cycle arrest and programmed cell death. This protein (p53) is activated by phosphorylation at target residues and phosphatases inactivate it, thereby the blockage of its degradation may have an anticarcinogenic effect. Oncogene activation (i.e., the expression of oncogenes), may alter diverse cellular processes including DNA replication, and thereby may lead to cancer development. The G-protein α subunit is a GTPase that hydrolyses GTP and thus has a major role in controlling the kinetics of the G-protein signaling cascade. Platelet-derived growth factor receptors (PDGFR) are kinase receptors that play roles in regulating cellular differentiation, cell proliferation and cell growth. PDGFR receptors are present on the surface of normal cells, however, it has been shown that mutations of the PDGFR genes that lead to their high expression lead to uncontrolled cell growth and consequently cause cancer (i.e., by increasing PDGF signaling).
Answer:
Explanation:
Let
x ----> the surface area of a sphere
y ---> the volume of a sphere
we know that
The ratio of surface area to volume of a sphere is equal to divide the surface area by the volume of the sphere
we have
substitute the values
