Answer:

Hope this helps!

Explanation:

Scientists say early plants may have contributed. Plants enhance a process called silicate weathering, which sucks carbon out of the atmosphere and ultimately tucks it away at the bottom of the oceans. Here's how it works: Caron dioxide in the atmosphere forms carbonic acid.

Tetrahydrofolate is important for the activity of which enzyme?
saul85 [17]

Answer:

GAR and AICAR transformylase

Explanation:

Tetrahydrofolate is essential for purine and pyrimidine synthesis, its deficiency can lead to inhibition of nucleic acid such as DNA and RNA and protein synthesis, which are important for the growth and survival of both normal cells and cancer cells. N-10-formyltetrahydrofolate acts as a donor of  carbon atoms to the actively growing bases. It contribution is mediated by the action of the Glycinamide Ribonucleotide (GAR) transformylase and the N-5-aminoimidazole-4-carboxamide ribonucleotide (AICAR) transformylase.

Addition of a nucleotide onto a dna strand is an endergonic reaction. what provides the energy to drive the reaction?
Kruka [31]

The release of pyrophosphate from the incoming nucleotide, and then hydrolysis of the pyrophosphate to inorganic phosphate provides energy for the addition of nucleotide onto a DNA strand.

Nucleotides are linked together by a condensation event that yields a tiny, stable molecule. But the released molecule is pyrophosphate, not water. A good amount of free energy is released when water is added to pyrophosphate.

The high-energy link between the ejected beta and gamma phosphates stores the energy for each incoming nucleotide's addition. The subsequent hydrolysis that occurs drives the process. A substantially greater quantity of energy is released when two phosphates are separated into individual phosphates.

A cell has 5% salt concentration. It is placed into a solution with a 0.5% salt concentration. What will happen to the cell
yaroslaw [1]

Answer:

The cell will shrink due to osmosis.

Explanation:

As in given question the salt concentration are much more inside the cell, than outside. In order to maintain equilibrium. the water inside the cell will start flowing outside in order to maintain equilibrium, causing shrinkage of cell. The ability of a cell to divide or function will reduce because of water loss. This phenomenon is seen in case of hypertonic solution. Water will start diffusing from the higher concentration to the lower concentration.
