3. Which type of molecule is more likely to quickly pass through a cellular membrane via simple diffusion, polar or nonpolar? Why?

The molecules most likely to pass through a cellular membrane are small molecules, whether they are polar or non-polar. Molecules such as oxygen and carbon dioxide (non-polar molecules) pass easily through the cellular membrane, as does water, a polar molecule.

Explanation: Hope this helps.

i think its control and coordinate because im pretty sure thats what tissue does and the joints are what control movement and then your skeletal/ bones provides portection. hope that .

yes it is weird but true
