Correct Answer is D

Explanation

An oxidation reaction occurs when there is a removal of electrons. Oxidation is the loss of electrons during a reaction by a molecule, atom, or ion. When oxidation occurs, the oxidation state of the chemical species increases.

The other options are not correct because they do not accurately describe what occurs in an oxidation reaction. Removal of oxygen, addition of carbon, and addition of neutrons are not processes that occur in an oxidation reaction.

A. Endoplasmic reticulum B. Cell membrane C. Chloroplast D. Golgi apparatus

Correct Answer is B

Explanation

The structure that is present in both prokaryotic and eukaryotic cells is the cell membrane ². The cell membrane is a thin layer that surrounds the cell and separates its internal environment from the external environment. It is composed of a lipid bilayer and proteins and regulates the movement of substances into and out of the cell.

The other options are not correct because they are not present in both prokaryotic and eukaryotic cells. The endoplasmic reticulum, chloroplast, and Golgi apparatus are organelles that are only found in eukaryotic cells.
