hmm for the pea pod question wasnt the stigma on the extreme left side, which was A?

 

[duck1300]

whats aids the plant? was it xylem vessels or root hair cell. as for the awsners im 100% sure of correct and i remeber them ill post them
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.
i forgot most of the questions tho

Yes. The anthers were there. And thats why I put A

 

[OrlandoBloom<3]

Yess I put A alssoooo ! Because the stigma is always present with the anthersss ! Or else how will pollination take placeee ?

 

[shahrukhsiddiqi]

yes so it is A

 

[duck1300]

sorry to burst ur buble it was D, i put B though
the reason its NOT A because A was at the bottom of the plant....., btw how old are you all?

 

[WayneRooney10]

:/
Well, what did you guys put for that over grazing question??

 

[yazan1995]

guys what about the question " which blood cell will digest the bacterial ...." something like that
is it A ?
i hope its A

 

[yazan1995]

:/

less nutrients and more soil erosion

Yup A

THe 2 doubts were the potato solution and which proceess is condensation
So please someone answer fast......!!

Shit. I wrote more nutrients. :/ As the plants wont no longer take nutrients up.

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

 

[Keeemoman]

Thank you although I am not sure about ur answers
Hope its wrong(lol)

 

[OrlandoBloom<3]

I have a feeling that the pod answer was A . I am pretty suree about it ! But then again I am not perfect

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

 

[OrlandoBloom<3]

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

 

[shahrukhsiddiqi]

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

yes. I wrote A as well.
