Turbines. Invented by Charles Parsons. I know I'm in middle school, but we are just learning about hydroelectric power.
Essentially the answer is in the names. Active transport requires energy to facilitate to movement of the materials while passive transport is something like osmosis which is when the material moves based on concentration in an effort to create equality between the two sides. Basically passive is when the materials move under the own power.
natural selection, bc it is the process whereby organisms better adapted to their environment tend to survive and produce more offspring
Answer:
reactions
Explanation:
Reactions occur when two reactant molecules effectively collide, each having minimum energy and correct orientation. Reactant concentration, the physical state of the reactants, and surface area, temperature, and the presence of a catalyst are the four main factors that affect reaction rate.
