4. VIRUSES
1- alive or not?
2– how they spread

6. VIRUSES
A strand of hereditary material surrounded by a protein coating

7. 7 CHARACTERISTICS OF LIVING THINGS:
Made of cells
Uses energy
Responds to stimuli
Maintains homeostasis
Grows and/or develops
can reproduce on their own
Contains genetic material (DNA or RNA)

8. Receptor proteins: protein that on the outside of the cell membrane that only reacts with specific things….. What does that make it?

9. How does it get in…..
1. the virus binds with a receptor protein
2. It enters the cell and uses the cells ribosomes to make more protein/viruses
3. They leave the cell in a vesicle made from the cell membrane and invade other cells using the original cell’s surface markers.
