If an element shares the same group as another element on the periodic table, what is one thing they have in common?
Same number of outer valence electrons, same chemical properties
What is the process by which organisms better adapted to their environment tend to survive and produce more offspring?
Natural Selection
What type of allele is expressed only when two copies are present?
Recessive Allele
What is the "Skin of the cell" that surrounds every cell called?
