Which of the following can combine in a cell to convert a lower-energy molecule into a higher-energy molecule?

Answer:
The reaction that converts a lower-energy molecule into a higher-energy molecule is ADP + P + energy.
Explanation:
ATP is the molecule that provides energy to the cell. It possesses three phosphate groups, each of which is bound by high-energy bonds and the separation of a phosphate by hydrolysis of ATP is strongly exergonic. The energy released is used by the cell to perform its functions.
<u>In order to form an ATP molecule, ADP is required to bind to a phosphate group, a process that requires energy </u>to establish the P-O-P bond, so the reaction, which is reversible, would be:
<em> ATP + H₂O ⇄ ADP + Pi + ↑energy </em>
This is what allows to convert a lower-energy molecule into a higher-energy molecule and permits an ATP molecule to become the energy exchanger of living organisms.

Answer:
a. all tall
Explanation:
If genotypically one of the parents is homozygous dominant and another one is heterozygous for plant height then phenotypically all their progeny will be tall.
Let us suppose, 'T' represents dominant allele and 't' represents recessive allele. Then the genotype of one parent who is homozygous dominant will be TT and genotype of another parent who is heterozygous will be Tt.
The cross is depicted in the attachment.
Here it may also be noted that genotypically two of the progeny will be homozygous dominant while two of the progeny will be heterozygous but phenotypically all the progeny will be 'tall'.
