The middle section that talks about active and passive transport

Diffusion- Passive transport

energy required- Active transport

exocytosis- Active transport

osmosis- Passive transport

endocytosis- Active transport

energy not required- Passive transport

facilitated diffusion- Passive transport

Protein pumps- Active transport

Explanation:

Passive transport can be described as the transport of particles along the concentration gradient i.e from an area of higher concentration to an area of lower concentration. This process does not require energy. For example, the phenomenon of osmosis

Active transport can be described as the transport of particles against the concentration gradient i.e from an area of lower concentration to an area of higher concentration. This process requires energy. For example, exocytosis

answer: land bridge theory. land bridge theory held that shifting portions of dry land explained the finding of identical species on different continents. plate tectonic theory eventually eliminated the land bridge theory.
