There are 4 nucleotides in DNA molecules: guanine (G), cytosine (C), adenine (A), and thymine (T).
Guanine and cytosine bind together (G-C), and adenine and thymine bind together (A-T). These are the only two possible binds in a DNA molecule.
Answer A has a guanine and adenine bond (G-A), which is impossible.
Answer B has a cytosine and cytosine bond (C-C), which is impossible.
Answer D has a cytosine and thymine bond (C-T), which is impossible.
Through the process of elimination, the answer is C.
Answer:
I believe the answer would be B because if I'm sure the bottom is grain which has higher levels in grain and glucose I believe and that doesn't produce energy . The second level is meat and that has protein which give us strength.
The organelle is labeled is nucleus, which means, where the chromosomes and one or more nucleoli are located immersed in the nucleoplasm or also karyolymph.
<h3>What is a nucleus organelle?</h3>
The nucleus, generally the largest eukaryotic cell organelle is the region delimited by membrane, where the chromosomes and one or more nucleoli immersed in the nucleoplasm or also karyolymph are located.
The nucleus of an organelle is composed of the karyotheca, chromatin, nucleoplasm and nucleolus.

Answer:
Ribosomes are found 'free' in the cytoplasm or bound to the endoplasmic reticulum (ER) to form rough ER.
Explanation:
In a mammalian cell there can be as many as 10 million ribosomes. Several ribosomes can be attached to the same mRNA strand, this structure is called a polysome.
