They have a cell membrane.
They can change over time.
They use energy to function.
They have the ability to reproduce.
The golgi apparatus is broken down during mitosis and then reformed. Which function would a cell be unable to perform during the time that its Golgi apparatus is broken down?
copying genetic material to include in the new cell
forming vesicles to import molecules into the cell
processing and packaging proteins for the cellular export
correcting errors in the process of building a new cell
Which characteristic is shared by all prokaryotes and eukaryotes?
Ability to store hereditary information
Use of organelles to control cell processes

Alveoli are microscopic air sacs in the lungs of mammals. Which statement BEST describes how the structure of alveoli allows lungs to function properly?
They increase the amount of energy transferred from the lungs to the blood.
They increase the flexibility of the lungs as they expand during inflation.
They increase the volume of the lungs, allowing more oxygen to be inhaled.
They increase the surface areas of the lungs, allowing efficient gas exchange.
The rough endoplasmic reticulum and Golgi apparatus work together in eukaryotic cells. What is one way that the rough endoplasmic reticulum assists the Golgi apparatus?
It assembles nucleic acids from monomers.
It breaks down old, damaged macromolecules.
It packages new protein molecules into vesicles.
It determines which protein molecules to synthesize.

Which statement best compares eukaryotic cells and prokaryotic cells?
Eukaryotic cells are smaller than prokaryotic cells.
Prokaryotic cells are more complex than eukaryotic cells.
Prokaryotic cells contain a distinct central organelle, and eukaryotic cells do not.
Eukaryotic cells contain membrane-bound organelles, and prokaryotic cells do not.
