The answer is <span>Polonium-218 (84 protons).
Alpha particles consist of two protons and two neutrons. So, mass is 4 (2+2) amu </span><span>.
</span><span>When an atom of emits an alpha particle, its atomic number will be reduced by 2 and a mass number will be reduced by 4:
</span> → + .<span>
After emission of the alpha particle from Radon-222 with 86 protons, the daughter product will have the atomic number reduced by 2: 86-2 = 84 and the mass number reduced by 4: 222-4=218:
</span> → + .
Three functions of a unicellular organism is its defense system, reproduction system, and its digestive system.
Catabolism of food molecules involves Hydrolysis reaction. It is the chemical bonds,its water breaks one or more chemical bonds.The cleavage of bio-molecules where a water molecule is consumed into component parts.
Hydrolysis reaction break the covalent bonds by consuming a water molecules and dividing its atoms between separate molecules these reactions are catabolic . It gives out energy and its exergonic. In this reaction large molecules are broken down into smaller ones.
There are some examples such as reverse of the condensation reactions described above. The process that dissolve a piece of bread into simple nutrients your body can use like glucose.

It is the evolutionary prosses by which populations become destinkt species
Hope this helps!
The formula to calculate population density is C. # of organisms in a region divided by land area.
Or # of organisms ÷ Land Area
Hope this answers ur question & helps!
