Question

name 2 structures only eukaryotic cells have. (refer to figure 3
organelles
nucleus
4 fill in the blank 1 point
one structure only prokaryotic cells have is a
cell wall
5 fill in the blank 1 point
the total metabolic activities of a cell are proportional to its
type your answer...

Explanation:

1. For question 4: Prokaryotes and eukaryotes can both have cell walls (e.g., plant eukaryotes have cell walls), so the correct unique structure for prokaryotes is a nucleoid (or a capsule, but nucleoid is the key defining one).
2. For question 5: A cell's metabolic activity is tied to its volume, as the volume contains the cytoplasm and organelles where metabolic reactions occur, while surface area affects nutrient exchange, not the total metabolic load itself.

Answer:

1. Nucleoid
2. Volume
