D: Heavy rain, cooler weather and clear days
The reason they have to be so accurate and precise is because, let's say you were doing a lab or something that was involving chemicals. If you had to put a certain amount of chemicals in your experiment, but when you were doing to the math, you messed up and didn't go back and even bother to fix it, that is a really BIG issue. Because something will probably happen to your chemicals because you might have added to much of something into it. So that's why you always have to be so precise and accurate!
Well, first off it tells you the number of valence electrons (because that’s what those are valence electrons) it also tells you how that atom is going to bond with other atoms (whether it will tend to loose or gain electrons when in chemical bonds). It also can show how reactive an element is (if it has eight or in some cases two then it won’t react because that outer shell is full)...basically it tells you the chemical properties of that atom
Answer:
b) More than two alleles exist
Explanation:
There are cases where more than two alleles determine a character in the population. This type of inheritance is called multiple alleles (or polyalelia). Classical examples of polyalelia are hair color determination in rabbits and blood groups of the ABO system in humans.
In the attached figure we can see another example of polyalelia where a flower is self-fertilized generating different phenotypes in its offspring.
