Term 1 of 42
Sam was walking through an alley when he spotted a small lump next to the dumpster. When
he examined the lump, he found that it was a newborn baby that was not breathing. He called
"911" to report the incident. When the police arrived, they questioned Sam regarding whether
the baby was alive when he found it. He said, "No." The baby was autopsied to determine if it
were alive or dead at birth. Which of the following results of the autopsy would prove that the
baby was born dead and not alive?
Discoloration of the lungs.
Dissected lung(s) floats in water.
Dissected lung(s) sinks in water.
Lungs collapsed.
Lungs inflated with fluid
Term 2 of 42
Which of the following is a way in which the cell increases gene expression in the nucleus?
Acetylation of histone tails
DNA methylation
Locating a gene within heterochromatin
Dephosphorylating DNA
Alternative splicing
,Term 3 of 42
Many important foods are fruits. Which of the following is not a fruit or part of a fruit?
Corn
Jalapeño
Rhubarb
Squash
Tomato
Term 4 of 42
A mother antelope and its child are galloping along the plains, when they encounter a group
of hungry lions. If the two antelopes try to escape the lions together, there is a 75% chance that
both will be consumed and eaten, and a 25% chance that both will escape alive. If, however,
the mother sacrifices herself to the lions, she may be able to buy her baby additional time to
escape. What is the minimum chance that the baby can have to escape from the lions following
such a sacrifice such that the mother's action will be evolutionarily favored? You may assume
that the baby antelope, once escaped, will be guaranteed to survive into a reproducing adult,
and that the mother antelope is at the beginning of reproductive age.

Lettuce seeds receive flashes of far red and red light in this order: far red, red, far red, red, red,
red, red, far red. The seeds will
Germinate since far red light induces germination.
Germinate since the first flash of light determines germination.
Germinate since there are more flashes of red light.
Not germinate since the flashes of light have destroyed the seeds.
Not germinate since only the last flash of light determines germination.
Term 9 of 42
Place the following statements regarding photosynthesis in C4 plants in the correct order:
I. ATP is used to convert pyruvate to phosphoenolpyruvate (PEP).
II. Mesophyll cells export four-carbon products such as malate through plasmodesmata to the
bundle-sheath cells.
III. PEP carboxylase adds CO2 to PEP to produce oxaloacetate.
IV. CO2 is used to produce G3P in the Calvin cycle.
V. CO2 is released in cells that contain the protein rubisco, which binds it.
