1. When we are in homeostasis, we are....
not healthy, sick
staying at home
dead or deceased
healthy, in our normal state
2. Sweating is a form of homeostasis....
yes
no
3. Homeostasis is the condition in which the body maintains:
A relatively stable internal environment, within limits
The lowest possible energy usage
A changing state, within an unlimited range
A static state with no deviation from preset points
4. Which of the following clues would tell you whether a cell is prokaryotic or eukaryotic?
whether or not the cell has membrane bound organelles
the presence or absence of ribosomes
whether or not the cell contains DNA
the presence or absence of a rigid cell wall
Which of the following types of cells utilize DNA as their genetic material but do not have their DNA encased within a nuclear envelope?
fungi
animal
plant
bacteria
6. What are the two main categories of cells?
eukaryotic & animal
plant and animal
prokayrotic & eukaryotic
prokaryotic & plant
7. Which of the following is not a difference between prokaryotic & Eukaryotic cells?

12. The Golgi Body is broken down during mitosis & then reformed. Which function would a cell be unable to perform during the time that its Golgi Body is not functioning?
Correcting errors in the process of building a new cell
Forming vesicles to import molecules into the cell
Processing & packaging proteins for cellular export
Copying genetic material to include in the new cell
13. Organelle containing a large range of digestive enzymes used primarily for digestion and removal of excess or worn-out organelles, food particles, and engulfed viruses or bacteria
cell wall
cell membrane
lysosome
mitochondria

Golgi bodies
ribosomes
chromatin
cytoplasm
