Answer:
Active transport requires cellular energy for substances to cross the cell membrane; passive transport does not.
Explanation:
Active Transport works against the concentration gradient and therefore needs energy to make it happen
Passive transport such as Diffusion and Osmosis uses the properties of natural movement of particles which moves the molecules from areas of high concentration to areas of low concentration or down the concentration gradient and happens passively without the need for energy
Nitrogen Containing Base. It can be either Adenine, Guanine, Thymine, Cytosine, Uracil

Answer:
Matter is conserved because atoms are conserved in physical and chemical processes. As complex as the water cycle is, water molecules are conserved and endlessly recycled in nature. Conservation of mass is a physical law that s never broken.This cycle continues with no loss of water.
