The drawing shown above is a micrograph of a cross section of a ureter. A patient becomes ill with a condition that prevents the tissue labeled B from functioning properly. What is the result of this condition?

A) If the smooth muscle does not function properly, the ureter cannot contract to drain urine from the kidneys.

B) If the smooth muscle does not function properly, the ureter cannot expand to accommodate the flow of urine.

C) If the epithelium does not function properly, the ureter cannot expand to accommodate the flow of urine.

D) If the epithelium does not function properly, the ureter cannot contract to drain urine from the kidneys.

The dna in a cell’s nucleus encodes proteins that are eventually targeted to every membrane and compartment in the cell, as well as proteins that are targeted for secretion from the cell. for example, consider these two proteins: phosphofructokinase (pfk) is an enzyme that functions in the cytoplasm during glycolysis. insulin, a protein that regulates blood sugar levels, is secreted from specialized pancreatic cells. assume that you can track the cellular locations of these two proteins from the time that translation is complete until the proteins reach their final destinations.for each protein, identify its targeting pathway: the sequence of cellular locations in which the protein is found from when translation is complete until it reaches its final (functional) destination. (note that if an organelle is listed in a pathway, the location implied is inside the organelle, not in the membrane that surrounds the organelle.)

Error analysis: what might be the reason that some of your percentages didn't exactly match your predicted results? gametes aren't responsible for inheritance. mice don't have large litters, so the sample size was not large enough. the wrong type of mice were used.

2. cheryl hears a new song on the radio every day during the week on her commute to work. surprisingly, when the song comes on at a party on saturday night, she knows most of the words without trying. describe the three ways that we use cognition to learn without reinforcement. which type of cognitive learning without reinforcement best explains how cheryl knew the song lyrics? explain your answer.
