Question

1. investigate: select the nuclear membrane closeup. how is the nuclear membrane similar to the cell membrane?

1. investigate: select the mitochondrion closeup. what happens inside the mitochondrion?

1. investigate: select the ribosome closeup. how does the cell make proteins inside the ribosome?

Explanation:

1. Both the nuclear membrane and cell membrane are phospholipid bilayers that regulate substance passage.
2. Mitochondria perform cellular respiration to produce ATP (energy) from glucose.
3. Ribosomes synthesize proteins via translation: they read mRNA and assemble amino acids into polypeptide chains.

Answer:

1. Both are phospholipid bilayers regulating substance movement.
2. Cellular respiration produces ATP (energy).
3. Ribosomes assemble proteins from amino acids using mRNA instructions.
