Answer:
A. temperature of the reaction
B. amount of enzyme
E. pH of the reaction
Explanation:
Temperature should be kept constant because enzymes operate at different activity rates depending on the temperature. The same goes for the pH as well with different enzymes having different optimal pH levels.
The amount of enzyme should be kept constant as well because different concentrations of enzymes can determine how fast the reaction will occur.
Essentially anything that could affect enzyme activity apart from substrate concentration should be kept constant.
Answer:
During conjugation, one bacterium serves as the donor of the genetic material, and the other serves as the recipient. The donor bacterium carries a DNA sequence called the fertility factor
Explanation:
Deposition
The wind deposited the particles
I THINK:
The DNA strands unwind, and
RNA polymerase binds to the
template strand.
The tRNA moves through mRNA
with the activated amino acids
attached to it.
The synthesis of mRNA begins.
The amino acids assemble
to form peptide.
The mRNA undergoes intron
splicing and exits the
nucleus.
(sorry in advance if it's wrong)
Answer:
The contractile vacuole pumps out excess water and wastes.
