We call a molecule that binds up excess hydrogen ions in a solution a(n) ________.
What is a base?
Plant cell walls contain which of the following in abundance?
What is cellulose?
A scientist randomly mutates the DNA of a bacterium. She then sequences the bacterium’s daughter cells, and finds that the daughters have many errors in their replicated DNA. The parent bacterium likely acquired a mutation in which enzyme?
Which molecule must enter the Calvin cycle continually for the light-independent reactions to take place?
What is RUBISCO?
Consider a cross to investigate the pea pod texture trait, involving constricted or inflated pods. Mendel found that the traits behave according to a dominant/recessive pattern in which inflated pods were dominant. If you performed this cross and obtained 650 inflated-pod plants in the F2 generation, approximately how many constricted-pod plants would you expect to have?
What are 217?
Which type of bond represents a weak chemical attraction?
What are hydrogen bonds?
Phospholipids are important components of ________.

What is DNA polymerase?
How many photons does it take to fully reduce one molecule of NADP+ to NADPH?
A farmer raises black and white chickens. To his surprise, when the first generation of eggs hatch all the chickens are black with white speckles throughout their feathers. What should the farmer expect when the eggs laid after interbreeding the speckled chickens hatch?
What is All the offspring will be speckled?
