Answer:
Explanation:
If we produced by mitosis then everyone would be the same. The would be no genetic differentiation. Because in meiosis, germ cells cross over and create zygotes with unique dna.
I'm not sure about number 1 or number 6, but I know that 3 is nucleic acid and 5 is solution.
The train traveled 100km (50x2) down and then 375km (75x5) up. So the train is 275km (375-100) up from where it started.
Answer:
D
Explanation:
This is because one of its orbital shells is not filled – the one with 1 electron. This atom will, therefore, want to lose this electron – it takes less energy to do this than gain 7 electrons -- to achieve stable electron configuration. This makes this atom very reactive in a chemical reaction. Usually orbital shells of atoms begin with an S orbital shell that is filled with 2 electrons then P (x,y,z) orbital shells filled with 6 electrons total. There are also higher energy f and d orbitals that each take a maximum 10 and 14 electrons respectively. An atom is stable if its orbitals are fully filled.
Animal dander would be the answer you're looking for.
Hope this helps :)
