That's because it's not?
The right answer is B, only growth and reproduction are shown by the diagram.
Please don't get confused by the characteristics of living things - these are easy points, so review this, since I think EVERY paper I've done has had a question about it and most likely, we'll have such a question tomorrow too.
Good luck!
Soorry i dnt get reproduction in the diagram is this asexual thts why??????
Thanks for the tip :)

You're right about all of them, including the last one.
The first one confused me though  :-\  ???
look at the arrows..

A and C- not possible as blood as blood cannot directly go to the lungs

D- not possible for blood to travel from lung to the rest of the body..

Reproduction :: Flower to fruit (recollect pollination), nothing to do with asexual.

deoxygenated blood from cells goes into heart. heart pumps the deoxygenated blood into the lungs to get oxygen. from the lungs ( now oxygenated blood) blood goes into heart again and gets pumped to the rest of the body. then the cirulation starts again.
double circulation = blood flows through the heart twice

Basically "xylem conducts water", that's what it means ;)

Please and thank you!


Sodium ions, Potassium ion, nitrate salts, nitrites salts, Ca and Mg ions .. anything else? (all dissolved in water)
