(Protein synthesis)
200
A scientist finds a new cell with a nucleus and mitochondria. What type of cell is it?
(Eukaryotic cell)
300
An atom has 8 protons and 10 electrons. What is its charge?
(-2, it’s an anion)
300
Which carbohydrate is used for energy storage in animals?
(Glycogen)
300
How many times more acidic is a solution with pH 3 than a solution with pH 6?
(1,000 times more acidic)
300
What structure controls what enters and exits a cell
Cell membrane/plasma membrane)
300
Why does eating too much saturated fat increase the risk of heart disease?
(Saturated fats contribute to plaque buildup in arteries.)
400
What makes an isotope different from a regular atom?
(Different number of neutrons)
400
Which macromolecule contains phosphodiester bonds?
(Nucleic acids - DNA & RNA)
400
Why does ice float on water?
(Hydrogen bonds create a less dense structure in ice.)
400
: What are two pieces of evidence supporting the Endosymbiotic Theory
(Mitochondria & chloroplasts have their own DNA, and they divide like bacteria.)
400
: Why would placing a freshwater fish in saltwater kill it?
Osmosis; water leaves the fish's cells, causing dehydration.)
500
Which type of chemical bond is the strongest in a biological system?
Covalent 
500
Why are saturated fats solid at room temperature?
(They have no double bonds, so they pack tightly.)
500
Why does sweating cool your body down?
(Evaporative cooling; high heat of vaporization of water.)
500
What is the function of the Golgi apparatus?
(Modifies, sorts, and packages proteins and lipids.)
500
A mutation stops an enzyme from functioning. What might have changed in the enzyme?
(Shape of the active site due to denaturation or genetic mutation.)
