• cytoplasm

• endoplasmic reticulum

• mitochondria

A student is developing a model that shows the steps of protein synthesis. The model should include activities in which three structures?

• ribosomes, rough endoplasmic reticulum, Golgi apparatus

• nucleus, Golgi apparatus, mitochondria

• mitochondria, rough endoplasmic reticulum, nucleus

• Golgi apparatus, nucleus, lysosome

• nucleus, cytoskeleton, cell membrane

Which of the following processes is directly controlled by the cell nucleus?

• Osmosis because the nucleus has nuclear pores that allow water to move in and out.

• Energy production because the nucleus contains mitochondria.

• Cell membrane assembly because the cell membrane is made from the nuclear envelope.

• Waste removal because a steady stream of molecules moves out of the nucleus.

• Protein synthesis because DNA in the nucleus contains the instructions for making proteins
