Answer:
active transport
Explanation:
Active transport is the energy-requiring process of pumping molecules and ions across membranes "uphill" against a gradient. The active transport of small molecules orions across a cell membrane is generally carried out by transport proteins that are found in the membrane.
I think that the answer is C.
Oxygen has a partial negative charge, whereas hydrogen had a partial positive charge.
This means that water molecules are polar and can be used to dissolve a lot of chemicals, that's why water is such a popular solvent.
Answer:
The Sun gives off energy to the solar panel which then gives power to the battery, which starts the car.
Explanation:
