Answer: Plant Cell
Explanation: Since I cant see in your question about what structure is about I have found that it might be the plant structure and I hope that this would help. I will also post you a picture of it.
A is Vacuole
B is Chloroplast
C is Cell membrane
D is Golgi bodies
E is Smooth and rough endoplasmic reticulum
F is Cell wall
This structure is a plant cell structure and it has a cell wall and plasma membrane.
Also, it has vacuoles in the center that are taking much space since they are huge.
Since it is a plant cell it has a chlorophyll and with it organelles and both of them are called chloroplasts.
Chlorophyll is giving the plant cell a green color. This kind of cell is a basic and the most important for the Plantae kingdom organisms.
Correct me if i'm wrong i think the best answer would be d. the cow uses all of the corn's energy for life processes.
All of the above are needed. Nucleotides are the basic building blocks of new DNA, ATP energy is needed because replication is an active process, and enzymes catalyze the reactions needed to carry it out (e.g. helicase to separate the strands to be replicated, DNA polymerase to build the new strands, and ligase to "glue" the fragments together).
