please explain to me about active and passive transport
i know passive transport is like high concentration to low concetration so it doesnt really require energy then theres diffusion, facilitated diffusion, and osmosis
for active trasnport theres like endocytosis and exocytosis but i dont understand the difference and what they are then endocytosis is split into pinocytosis and phagocytosis (which is like eating the cell??? please explain!!) thanks

They don't really seem to have created a very good theory. They just seem to try and poke holes at evolution without providing evidence for an alternative theory. In fact they don't even have an alternative theory. What do you think?

I asked the Q: 'why do you see stars better from the corner of your eye than if you look at it directly?' -- is it to do with the blind spot

i now know that it is definitely the fovea (area in the retina with the most light- sensitive cells) that creates this - but how/why? (details?)
