Molecules in the solid phase have the least amount of energy, while gas particles have the greatest amount of energy.There are space between particles of matter. The average amount of empty space between molecule gets progressively larger as a sample of matter moves from the solid to the liquid and gas phases.
Chargaff's rules state: adenine is complimentary to thymine and cytosine is complimentary to guanine. For this question, in order for polymerization of the growing complementary strand, guanine must bind with cytosine.

Bacteria perform important functions in the soil, decomposing organic residues from enzymes released into the soil. Each functional bacteria group plays a role in recycling soil nutrients.
Answer:
d. ATP; Fructose-2,6-bisphosphate
Explanation:
Phosphofructokinase-1 is the enzyme that catalyzes the formation of fructose-1,6-bisphosphate from fructose-6-phosphate and ATP. The phosphofructokinase step is the first rate-limiting step of glycolysis.
Phosphofructokinase-1 activity is allosterically regulated. Its activity is increased whenever the cell's ATP supply is depleted or when its breakdown products, ADP and AMP accuulates in he cell. However, it is inhibited when the cell is amply supplied with ATP.
The activity of phosphofructokinase-1 is restored by fructose-2,6-bisphosphate, its most potent activator.
From the given options:
a. AMP :::: citrate is wrong because AMP increases the activity of phosphofructokinase-1 and citrate is not its activator but an inhibitor
b. AMP :::: Fru-2,6-P2 is wrong because AMP increases its activity same as fructose-2,6-bisphosphate
c. ATP :::: citrate is wrong because both citrate and ATP are inhibitors
d. ATP :::: Fru-2,6-P2 is correct as explained above
e. All of these is wrong because of the other wrong options above.
