1) When you increase the temperature in a system, enzymes have a habit of denaturing. Explain what is happening in relation to the Gibbs Free Energy Equation: ΔG = ΔH – TΔS. Remember, in order to maintain a highly ordered system, energy needs to be used for maintenance. If the free energy decreases, then spontaneous reactions occur.

First Define:
ΔG:
ΔH:
ΔS:
T:

Explain:

2) As you get older, your mitochondrial DNA mutates which means that your energy production will decrease. Using the Gibbs Free Energy Equation: ΔG = ΔH – TΔS, please explain old age.

Which best describes red blood cells? a. they are colorless b. they protect against disease-carrying microorganisms c. they transport oxygen throughout the body d. they aid in blood clotting

According to the big bang theory, after the "bang," the universe remained dark until about  300,000 yearsone billion yearsthree minutesthree billion years  later, when neutral atoms began to form.

Considering the yellow and green pea color phenotypes studied by gregor mendel: a. what is the biochemical function of the protein that is specified by the gene responsible for the pea color phenotype? (1 point) b. a null allele of a gene is an allele that does not specify (or encode) any of the biochemical function that the gene normally provides (in other words, either no protein at all or only non-functional protein is produced from it). of the two alleles, y and y, which is more likely to be a null allele? (1 point) c. in terms of the underlying biochemistry, why is the y allele dominant to the y allele? (2 points) d. why are peas that are yy homozygotes green? (1 point) e. the amount of protein produced from a gene is roughly proportional to the number of functional copies of the gene carried by a cell or individual. what do the phenotypes of yy homozygotes, yy heterozygotes, and yy homozygotes tell us about the amount of sgr enzyme needed to produce a yellow color? explain your reasoning.
