If my friend was to say that I would say that the prediction are scientifically drawn. They look at the current state of the atmosphere. They also make educated guesses regarding previous weather patterns in that given area.
1.0mm= (1x10^-6) L
So , (1x10^-6) x (7.0x10^6)
=7
The correct answer will be C. Carbon and Oxygen because these both are non metals and non metals react colvalently (i.e share electrons) while when metals react with a non metals they react ionically (i.e lose and gain electrons)
Here’s what I would put down:
Kidneys couldn’t work without the BLOOD because WASTE couldn’t leave the body. Hope this helps
