sensitivity,palidise since it has many chloroplasts,the o2 from the mother to the fetus,red blood cell has no nucles and transport substances, the rate of breathing was the 1 was alot of zigzags,sugar,motor neurone(I put sensory neurone x_x), the blood cell that digest bacteria was A which is a phaygophycte.

Condensation is when clouds are formed. Potato solution diffusion yes, no osmosis

@waynerooney why no osmosis?? (when it is boiled the cell membrane is destroyed so the membrane will be fully permeable and water moves from area with high w.p to low w.p and also diffusion takes place for the sugar)

osmosis is always across a partially permeable membrane.

The potato question the answer is C ( no osmosis but diffusion is there )
And the condensation question .. The answer is A

There will be no osmosis because if you recall the definition of osmosis it states : Osmosis is the movement of water molecules from a region of high concentration to a region of lower concentration across a partially permeable membrane . When the potatoes were boiled the membrane was destroyed and hence no osmosis can take place :)

i am still not sure about the correct pea pod answer but i believe it was A because that lookes like a stigma and where the pollen grain would have entered
