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> → + .
Yes, it’s possible. The genetic that they give out to their children depends. If the parents gives out the genes for colorblind for the daughter but not the son, it’s possible.
It’s just like having a child with disabilities and another child that is perfectly healthy.
Answer:
C. The number of differences in a specific DNA sequence of two species is multiplied by a known mutation rate to determine the number of years of evolution that separate the two species.
Explanation:
This is the best explanation of a way that a molecular clock can be used!
A cell's relatively constant internal physical and chemical conditions are called homeostasis. This will make the correct answer B.
Answer D. Cells of the new individual would have double the necessary number of chromosomes.
