The following options are attached to the question above:
A. A unicellular prokaryote
B. The shell surrounding a pilus
C. A type of virus
D. A particle that attacks viruses
ANSWERS
The correct option is A.
Bacteria are unicellular organisms, which have no true nucleus and they possess simple internal structures. They are microscopic organisms and they can be found in diverse places such as in the soil, ocean, in the human gut, in the air, etc. Bacteria are usually very small in size and large number of them usually exist together as a community. Bacteria are responsible for a large number of diseases in plants, animals and humans.

The kind of cell division that goes with growth is Mitosis. Mitosis cell division is accompanied by cellular enlargement and differentiation, so there is an increase in size and weight. I hope this helps!

Answer:
An amino acid has a common skeleton structure; an alpha carbon joined to 4 groups in its four covalent bonds. The groups are a Hydrogen (-H), a Carbonyl (-COOH), an Amino group (-NH3), and a side chain.
The side chains are variable across all amino acids which is the basis for their identification and naming. The side groups have different properties, therefore, giving different amino acid different structures and properties. These properties help in the folding of polypeptide chains into functional protein structures. This is due to their various interactions between the different amino acids that help proteins form structures like disulfide bridges, beta-sheets and alpha-helices.
