Bio 150 Final Exam Question and
answers 100% correct (28 pgs)
Properties of life - correct answer ✔Organized complexity, metabolism, can
reproduce, can respond to their environment, composed of cells
Ions - correct answer ✔Numbers of protons and electrons differ
Most common elements found on earth - correct answer ✔Nitrogen, oxygen,
carbon, hydrogen
nonpolar covalent bond - correct answer ✔Electrons shared equally, similar
electronegativity
polar covalent bond - correct answer ✔one atom has a much higher
electronegativity
molecule - correct answer ✔two or more atoms held together by covalent
bonds
hydrogen bond - correct answer ✔weak association formed between polar
molecules
cohesion - correct answer ✔water and water
adhesion - correct answer ✔water and other polar molecules
Cation - correct answer ✔positive ion
,anion - correct answer ✔negative ion
Why does ice float? - correct answer ✔It is less dense than water, H bonds
cause molecules in ice to spread farther apart. This is important for aquatic
organisms.
Function groups - correct answer ✔groups of atoms that together have
specific chemical properties.
Five functional groups - correct answer ✔hydroxyl (-OH), carbonyl (C=O),
carboxyl(C=O-OH) , amino(N-H-N), phosphate
dehydration synthesis - correct answer ✔build up polymers
Hydrolysis - correct answer ✔break down of polymers by addition of water
Carbohydrates - correct answer ✔1:2:1 ration of carbon, hydrogen, and
oxygen C6H1206
How are carbohydrates linked? - correct answer ✔glycosidic bonds
Function of carbohydrates - correct answer ✔Energy source

Lipids bonds - correct answer ✔ester linkage
Nucleic acids bonds - correct answer ✔phosphodiester bonds
Nucleic acids makeup - correct answer ✔5 carbon sugar, phosphate group,
nitrogenous base
