In which two layers of the atmosphere are temperatures generally warmer at higher altitudes? A- mesosphere and troposphere
B- troposphere and stratosphere
C- mesosphere and stratosphere
D- stratosphere and thermosphere

i believe the answer is c

i guess because love can be toxic ‍♂️

passive transport is a movement of biochemicals and other atomic or molecular substances across cell membranes without need of energy input. unlike active transport, it does not require an input of cellular energy because it is instead driven by the tendency of the system to grow in entropy.

so, according to what that says, i believe it's hypertonic and hypotonic.

good luck!
