a scientist observes that the population of a viral strain remains constant when stored in a sterile test tube. However, the population increases exponentially when incubated in a mouse. What can be concluded from the scientist's findings

trachea, alveoli, lung capillaries, arteries

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!
