Explanation:
1. cell membranes are partialy permeable, only allowing passage to some certain molecules.
2. diffusion is the movement of molecules across partially permeable membrane down concentration gradient.
3. the molecules are too big to pass through partially permeable membrane. the concentration of the molecule might be higher in the cell than in the solution/surroundings.
A gas. This is because none polar solvents contain binds between atoms with similar electronegativities, some examples are carbon and hydrogen
Calcium oxide based on the above explanation is an ionic compound.
D. Infrared images can show hot spots as red areas.
bacteria can live in hotter and colder temperatures than humans but they do best in a warm moist protein-rich environment that is pH neutral or slightly acidic
