The correct answer is "active transport is ATP dependent whereas in passive transport molecules use kinetic energy to move across the membrane." in  active transport cells use molecules embedded on the cell membrane called carriers in the presence of energy. cells use energy and carriers because molecules must move against concentrated gradient inside the cell. on the hand, passive transport is a process by which molecules move from the region of high concentration to the region of low concentration across plasma membrane until balance is obtained on both sides of the membrane. once equilibrium has been achieved in passive transport the movement of molecules stops.     
        
             
        
        
        
Radi Carry developed a theory named "<span>Spontaneous generation". This theory assumed that living creatures can be generated from non-living things and he used this theory in order to explain the origin of flies.
He carried out another experiment with three jars to check that bad air did not cause any flies.</span>

Answer: The cell membrane invaginates and pinches off, creating a vesicle within the cell.
Explanation:
Endocytosis is an active transport mechanism, for particules to be transported, the plasma membrane of the cell invaginates, forming a pocket around the target particle. The pocket then pinches off, resulting in the particle being contained in a newly created intracellular vesicle formed from the plasma membrane.
 
        
             
        
        
        
The two types of microscopes are electron and optical microscopes. 
Electron microscopes have a higher magnifying power since it uses lighting technology to do so.
Hope it helped,
Happy homework/ study/ exam!
