d. plant

Explanation:

First Question:

An isotonic solution has the same solute concentration as the cell's interior. So, there's no net movement of water (osmosis) across the cell membrane, and the cell size remains unchanged. Hypotonic solutions have lower solute concentration, causing water to enter the cell (cell swells). Hypertonic solutions have higher solute concentration, causing water to leave the cell (cell shrinks).

Prokaryotes (e.g., bacteria) lack a true nucleus. Eukaryotes (including animal and plant cells) have a membrane - bound nucleus. Animal and plant cells are types of eukaryotic cells, so they have a nucleus.

Prokaryotic cells (like bacteria) do not have a membrane - bound nucleus. Eukaryotic cells (animal and plant cells are eukaryotic) have a nucleus. So, prokaryotes are the cells without a nucleus.

Answer:

B. Isotonic
