11 All of the following are characteristics of both living organisms and cells EXCEPT:
A remove waste from themselves
B rely on chemicals for communication
C grow and die
D extract energy from food

the answer is c.the valence of the atoms combine .

considering the question as per the attachment

here we can see that the radon nuclide has 222 as the atomic mass number and 86 as the atomic number.

when it undergoes nuclear fission it gives polonium which has atomic mass number as 218 and atomic number will be 84 along with a helium nucleus which has 4 atomic mass number and 2 as its atomic number.

222 = 218 + 4 (atomic mass number)

86 = ? + 2; therefore ? = 86-2 = 84.

the atomic mass number of polonium will be 84.

plasma - state of matter made up of electrically charged particles

it would only be the stuff in module eight so you need to study all the lessons in that you also could check the flvs

hope this : )
