SIckle cell anemia is a disease caused by the substitution of an incorrect nucleotide into the DNA sequence for a particular gene. The amino acids are still added to the growing protein chain, but the symptoms of sickel cell anemia result. This is an example of
frameshift mutation
missense mutation
nonsense mutation
thymine dimer mutation

A behavioral endocrinologist captures male individuals of a territorial bird species over the course of a year to measure testosterone (T) levels. In this population, males may play one of two roles: (1) they may stay in their natal group (the group they were born in) and help raise their younger siblings, or (2) they may leave their natal group to establish a new territory.
Testosterone level in this population may be an example of
adaptive radiation
an adaptation
divergent selection
development

In this population, males may play one of two roles: (1) they may stay in their natal group (the group they were born in) and help raise their younger siblings, or (2) they may leave their natal group to establish a new territory.
What can you infer about the role of testosterone in reproduction in this species?
It is detrimental to breeding
It aids adult males only
It ensures that all males reproduce equally
It aids in breeding

A researcher grows a population of ferns in her laboratory. She notices, after a few generations, a new variant that has a distinct phenotype. When she tries to breed the original phenotype with the new one, no offspring are produced. When she breeds the new variants, however, offspring look like the new variant result.
What originally caused the change in the variant?
karyotyping
balanced polymporphism
mutation
polyploidy

An eager AP Biology student interested in studying osmosis and the movement of water in solutions took a dialysis bag containing a 0.5M solution and placed it into a beaker containing a 0.6 M solution.
After the bag has been sitting in the beaker for a while, what would you expect to have happened to the bag?
There will have been a net flow of water out of the bag, causing it to decrease in size.
There will have been a net flow of water into the bag, causing it to swell in size.
The bag will be the exact same size because no water will have moved at all.
The solute will have moved out of the dialysis bag into the beaker.

An eager AP Biology student interested in studying osmosis and the movement of water in solutions took a dialysis bag containing a 0.5M solution and placed it into a beaker containing a 0.6 M solution.
If this bag were instead placed into a beaker of distilled water, what would be the expected result?
There will have been a net flow of water out of the bag, causing it to decrease in size.
There will have been a net flow of water into the bag, causing it to swell in size.
The bag will be the exact same size because no water will have moved at all.
The solute will have moved out of the dialysis bag into the beaker.

The solutions in the two arms of this U-tube are separated by a membane that is permeable to water and sodium chloride, but not to sucrose. Side A is filled with a solution of 0.6M sucrose and a 0.2 M sodium chloride (NaCl), and side B is filled with a solution of 0.2M sucrose and 0.3M NaCl. Initially the volume on both sides is the same.
At the beginning of the experiment,
Side A is hypertonic to side B
Side A is hypotonic to side B
Side A is isotonic to side B
Side A is hypotonic to side B with respect to sucrose
