THIS IS FOR A CHECKPOINT, PLEASE ANSWER: A scientist discovered a new organism with the following characteristics. * Multicellular * Eukaryotic * Heterotroph * Reproduces sexually * What kingdom does this new organism belong to?

radioactive decay occurs in unstable atomic nuclei – that is, ones that don't have enough binding energy to hold

the nucleus together due to an excess of either protons or neutrons.

so here we go

atomic mass

239 + 1 = y + 134 + 3 combine like terms

240 = y + 137             subtract 137 from both terms

240 - 137 = y

103 = y

atomic number

94 = z +54 + 0

94 = z + 54               subtract 54 from both sides.

40 = z

answer

12 is it do you think so
