C. The rate of harvest does not exceed the fish population's rate of recovery.
The first organisms to inhabit Earth were prokaryotes that
lived 3.5 billion years ago. prokaryotes are well organised, achieving all of an organism’s life functions
within a single cell. These were the precursors to eukaryotic cells
B, a nucleus. Nuclei are membrane-bound organelles inside eukaryotic organisms. Eukaryotes are protists, fungi, plants, and animal cells. A bacteria is not a eukaryote, it is a prokaryote, so it does not have the membrane-bound structure of the nucleus.
Be careful, though, bacteria still have DNA. It is simply located in the center of the cell and is not encased in a membrane.
