What's the common concentration of a potato cell?

Are the questions too vague or else?...........

My Norton update is going to expire soon. Will it affect my liveupdate? Do I need to fill in the serial number? Is that the same for me to find the update file in the norton web site and do it myself?

Is engineering more interested than science?

Cell X is turgid?

Two questions. They may be very simple and easy for you, but a brain flash. 1.the square root of 20 consecutive positive intergers have the same intergral number, find that number. 2.(a-b)(c-d)/[(b-c)(d-a)=3 Find (a-c)(b-d)/[(a-b)(c-d)]

What's the colour of chromium metal?

Isn't the water potential inside increased since the solute concentration is lowered?

isn't there a net movement of water into the cell and thus into the cytoplasm?

Fancy there has a beaker with water, a potato without skin is put at the central of the beaker. There is a cavity on the potato,about 7 cm. The cavity is contained with a sucrose solution. The water potential outside is higher than that of the sucrose solution. The cell membrane is a differentially permeable membrane. After ten minutes, if we cut a small cell from the cavity region and observe under microscope. What's the appearence of the cell? Flaccid, plasmolysis or turgid?

When will the mod be taughted to us? I learnt it myself.

I found both information from the internet. One says yes , the other says no.

Yes, I think they will. Strong electrostatics forces between a charged substance can repel or attract electron from a substance. If the force is moderate enough, the electron would not be pulled away or stay at the position, instead the whole substance moves.

This is not much related to the title but I want to consult on. Does carbon dioxide like sulphur dioxide gives ions when it is dissolves/react in water? I'd think it won't since aqeuous carbonic acid is unstable, I think:P

All atoms of noble gases have their outermost shells completely filled with electrons. Anyone have idea?

Where does the big file come from?

Really troublesome question....

Much clear and better than mine!LOL!

Yeah! Bingo!

Really? I thought it was usual for foreigners. By the way, thank you

Cells are the basic and structural unit of an organism. Cell wall protects, gives shape and support the cell. Nucleus contain genetic materials responsible for heredity and it controls all activities of the cell. Hope it help for some of the questions!

ARe Norway and Sweden very friendly with Finland? How to write a better composition? I always fail:P

Ya Certainly better. I still have a question. Isn't the pressure by the sugar solution area more than the pure water? It has a higher density

I am not

"peng" is entrophy?
