Cell Structure and Function
If a mutation occurred at a single locus in an organism's DNA sequence and did not affect phenotype or fitness, this change would best illustrate which concept within population genetics?
How does secondary active transport differ from primary active transport?
What type of transport is required for potassium ions to move against their concentration gradient across a cell membrane?
Which method would provide the most reliable information when determining whether species share common ancestry based on molecular data?
When considering the bottleneck effect, what outcome would you expect for genetic diversity within a population after a catastrophic event?
What would likely occur if aquaporins in plant root cells were mutated so that they no longer functioned properly?
What type of transport requires energy to move substances across a cell membrane?

Which process would most likely result in a net uptake of glucose by intestinal epithelial cells when the glucose concentration is higher inside the cells than in the gut lumen?
What systemic consequence can arise if aquaporins lose selectivity allowing ions along with water through?
If a cell is placed in a solution where the concentration of nonpenetrating solutes outside the cell is higher than inside, what will happen to the volume of that cell over time?
