Answer:
A polar molecule simply means the charges are not exactly even throughout the molecule. Some parts are slightly negative (outside the oxygen), and some parts are slightly positive (outside the hydrogen atoms). Water is polar because the highly electronegative oxygen atom attracts electrons to it, making the region around the oxygen more negative than the areas around the two hydrogen atoms. This concept is important to understand how water bonds.
Answer:
you didnt really give us the list to choose from

Hey there!
I think you mean the Finches. Each Finch has a beak that is very similar to other beaks on the other islands. This shows that they are related. Their beaks change so that they can live better in their environment. They all had a common ancestor.
I hope this helps!
1) Cells duplicate their chromosomes before dividing instead of after because the daughter cells would each lose one-half of the genetic information.
The duplication of chromosomes automatically leads to the duplication of the genetic information on the chromosomes and each daughter cell receives a copy each of the genetic information.
If the information are not duplicated before dividing, it means that each daughter cell will receive half information.
2) If a cell that starts with 16 chromosomes lost half of its genes during each cell division, it will take 4 divisions for the gene to remain 1.
- First division, the genes would remain 8 from 16
- Second division, the genes would remain 4
- Third division, the genes would remain 2
- Fourth division, the gene would remain only 1.
