Can sound energy pass through an empty space?

Never. Sound propagates as longitudinal waves which are a kind of mechanical waves. These waves require a medium for them to pass. The medium can be either solid, liquid or gaseous. Thus, in empty space i.e. vacuum, sound can never pass.


What are two types of cellular transport that do not require energy?

Passive transport never requires energy - hence the name passive. Active transport requires the input of energy. Two types of active transport are; primary (using pumps) and secondary (using anti or symports).


When do you hire a Transport Security?

Never


Why is it that energy is never transfered in a direction opposite to the direction of wave propagation?

Energy is not transferred in the opposite direction of wave propagation because waves transport energy through oscillations or disturbances in a medium. These disturbances can only move in the direction of the wave itself, not against it. In a wave, energy is transferred from one point to another by the movement of the wave particles in the same direction as the wave itself.


Can you transport a refrigerator on its back?

Never


Does active transport require transport proteins?

Yes, active transport does require transport proteins. These proteins use energy to move molecules against their concentration gradient, typically from an area of low concentration to high concentration. This process is essential for maintaining cellular homeostasis.


What would you do if transport was never invented?

Walk. Alternatively, I'd invent transport myself!


What doesn't produce ATP?

ATP is not produced by passive transport processes like diffusion or osmosis. It is also not directly produced by light energy, but rather by the process of photosynthesis in plants using light energy. Additionally, ATP is not produced by the electron transport chain in anaerobic respiration.
