Question: Gina has longer fingernails than John. Who has more cells on their nails? 
 Answer: Gina
As the nail grows, more cells are added at the nail bed.

Question: John was playing with alkanes in his lab. If he increased the amount of carbon atoms in an alkane, what would happen to the boiling point of that alkane? 
 Answer: increase
Alkanes with more carbon atoms have higher boiling and melting points, so some of them are solids at room temperature.

Question: John was comparing different fossils in his collection one day. If he were to compare characteristics of a very recent fossil in his collection to an animal alive now, what would he find? 
 Answer: high similarity

In general, fossils in older rocks are less similar to modern organisms.
