What is the arm used for on a microscope?
The arm connects the body tube to the base of the microscope.
What's the difference between Prokaryote cells and Eukaryote cells?
Prokaryotic cells do not have an enclosed nucleus, very few organelles, ex. Bacteria. Eukaryotic cells characterized by the presence of a nucleus and other membrane-bound organelles, ex. human or plant
What is asexual reproduction?

What is the Golgi apparatus?
modifies, packages, and ships proteins
What is homeostasis?
homeostasis is the state of steady internal physical and chemical conditions maintained by living systems.
What is a J-curve?
It shows when a population doesn't have limits.
What is the cell theory?
All living things are made up of cells, cells are the basic units of structure and function in living things, new cells are produced from existing cells
What is the Diaphragm on a microscope?
This diaphragm has different sized holes and is used to vary the intensity and size of the cone of light that is projected upward into the slide.
