<h3><u>Answer;</u></h3>

It was developed by many scientists over many decades.

<h3><u> Explanation;</u></h3>
  • DNA is a type of nucleic acid that contains two long, twisted strands, known as double helix, that contain complementary genetic information.
  • A gene is a segment of DNA that is passed down from parents to children and confers a trait to the offspring.
  • The traits an organism displays are ultimately determined by the genes it inherited from its parents, known as genotype.
  • Our understanding of DNA and inherited traits has changed over time since it has been continuously developed by many scientists over may decades.

The Gibbs free energy change of a reaction can be calculated using the equation ΔG = ΔH – TΔS. A biochemical reaction that can p
Katena32 [7]

Answer:

a. ΔG was negative.

Explanation:

The answer is a. ΔG was negative because, for a biochemical reaction to occur and provide energy for cellular metabolism, the Gibbs free energy ΔG = ΔH - TΔS < 0 , for spontaneity. If all terms on the right were to be negative, then ΔG = -ΔH - (-TΔS) = TΔS - ΔH and would only be less than zero if the absolute value of ΔH > absolute value of TΔS. If ΔG was positive as in C, the reaction would not be spontaneous and energy would have to be put into the biochemical reaction for it to occur. If all terms on the right were positive, then, ΔG = ΔH - TΔS < 0 when TΔS > ΔH , else ΔG > 0 and energy would have to be put into the biochemical reaction for it to occur, so its not spontaneous.
