Which of the following is the process in which an ovarian follicle matures and releases a reproductive egg?

Viruses lack the essential machinery needed to reproduce by themselves.

In fact, viruses can only reproduce after infecting a living cell - a process called viral replication.

Once inside a living cell, viruses re-program the cell’s machinery to produce viral proteins and genetic material to make new copies of themselves.

Choice A, Bacteria, is not the correct answer because bacteria have their own metabolic pathways and can reproduce outside of a host cell.

Choice B, Protozoa, is also not the correct answer because protozoa are single-celled eukaryotes that have their own metabolic pathways and can reproduce outside of a host cell.

Choice C, Helminths, is not the correct answer because helminths are multicellular parasitic worms that have their own metabolic pathways and can reproduce outside of a host cell.

The cell membrane is a thin, flexible barrier that surrounds all cells and separates the inside of the cell from the outside environment.

It is composed of a lipid bilayer and regulates the movement of substances into and out of the cell.

Choice B is incorrect because the Golgi apparatus is not present in prokaryotic cells.

The Golgi apparatus is an organelle found in eukaryotic cells that is involved in modifying, sorting, and packaging proteins and lipids for transport to other parts of the cell or to be secreted outside the cell.

Choice C is incorrect because chloroplasts are not present in prokaryotic cells.

Chloroplasts are organelles found in plant cells and some algae that are responsible for photosynthesis.

Choice D is incorrect because the endoplasmic reticulum is not present in prokaryotic cells.

The endoplasmic reticulum is an organelle found in eukaryotic cells that is involved in protein synthesis and lipid metabolism.
