1. When we are in homeostasis, we are....
not healthy, sick
dead or deceased
healthy, in our normal state
staying at home
2. Sweating is a form of homeostasis....
no
yes
3. Homeostasis is the condition in which the body maintains:
A static state with no deviation from preset points
The lowest possible energy usage
A changing state, within an unlimited range
A relatively stable internal environment, within limits
4. Which of the following clues would tell you whether a cell is prokaryotic or eukaryotic?
the presence or absence of ribosomes
the presence or absence of a rigid cell wall
whether or not the cell has membrane bound organelles
whether or not the cell contains DNA

bacteria
plant
fungi
animal
6. What are the two main categories of cells?

Copying genetic material to include in the new cell
Correcting errors in the process of building a new cell
Processing & packaging proteins for cellular export

Golgi bodies
chromatin
cytoplasm
ribosomes
