Answer:
26%
Explanation:
if cytosine makes up 24%, then guanine also makes up 24%.
add these to get 48%.
subtract that from 100% to get a remaining 52%
then split the 52% between adenine and thymine to tell you that 26% is thymine

Answer:
B
Explanation:
The folds contain ribosomes attached to the membrane. The more the folds the more the surface area to which more ribosomes can attach. The ribosomes are organelles responsible for the manufacture of protein in cells. Thereafter, the proteins are properly folded by the mediation of chaperones in the lumen of the RER.
Answer:
D. The statement is inaccurate because humans would not be able to distribute the product of nitrogen fixation from industrial processes in the same way that bacteria are able to distribute it globally now.
Explanation:
Nitrogen fixing bacteria has the responsibility in nature to trap and fix atmospheric nitrogen in ecosystems. They are very important components of the nitrogen cycle and play an important role in maintaining the balance of nutrients in nature.
If humans discover industrial processes to fix nitrogen, the process will be unsustainable in the long run if nitrogen-fixing bacteria ever go extinct because humans would not be able to distribute the product of nitrogen fixation from industrial processes in the same way that bacteria are able to distribute it globally now across several ecosystems all over the world.
