Question:

How do you determine if a certain molecule is polar?

Michael V.
Answer:

There are multiple ways to determine this. By far the easiest would be to simply draw a lewis structure of the molecule. Based off of the symmetry you can determine if the molecule will either be polar or nonpolar.

Biology

Question:

What is the basic unit of DNA?

Michael V.
Answer:

Nucleotides. It is common to mix up the basic functional units of Protein and DNA, but with most things that are biology, you are just going to need to memorize terms. I like to remember by using the N in DNA, with the N in Nucleotides.

Algebra

Question:

Does 2/0= 0?

Michael V.
Answer:

No. Remember that is very common for people to misunderstand fractions. Many people will see that 0/2= 0 and will think that the reciprocal must also equal 0. Remember that anything divided by 0 is undefined.
