loris [4]

Answer:

c) pure water on the produce would put it in a hypotonic environment and keep the produce firm.

Explanation:

Ideally, in a natural environment, plants leafs remain fresh and firm looking by absorbing water from their natural environment. However, in a case where these vegetables have been removed from their natural environment, they have lost the ability to absorb water under natural conditions.

In order to keep the leaf cells of the vegetables firm and rigid, so they can look fresh and appealing, they have to be placed in a hypotonic condition i.e. an external condition with high concentration of water. To do this, a grocer in a supermarket will occasionally spray the vegetables with pure water to keep the vegetables' cell from drying out and hence lead to wilting, which would make the vegetables less appealing to customers.

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.
