ex. peanuts
🗑
|

| pathogens | any organism that produces a disease
🗑

🗑
|
||||
| host cell | a living cell that the virus takes over
🗑
|
||||
| latent | -when a virus is inactive
-when the virus is present but not actively reproducing
🗑
|
||||

| What does a T-4 virus look like? | -protien coat
-has DNA inside the protein coat
🗑
|

| What makes a virus living or non-living? | Living
-reproduce
Non-Living
-don't grow
-don't eat (get energy)
-doesn't respond to its environment or adjust to their surroundings
🗑

| Reproduction Steps for a virus | 1. The virus attaches to a healthy cell
2. The DNA of the virus is put into the cell
3. The DNA of the virus takes control of the cell's functions
4. The virus directs cell to make new DNA and protein coats
5. Cell bursts open and viruses attack new c

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
