| | | | | | | | | | | |
|membrane: cholesterol |
3. Loosely coiled DNA wrapped around histone proteins is called:chromatin
| | | | | | | | |
4. The main function(s) of the cell membrane is to:separate the cell's contents from the
| | | | | | | | | | | | | |

5. What type of passive transport occurs when water and solutes are forced through a membrane using
| | | | | | | | | | | | | | |
|hydrostatic pressure?: filtration | |
6. The ability of a solution to hold onto water or pull water into the solution across a semi-permeable
