AP Bio Mock Exam Questions and Answers 2024

AP Bio Mock Exam Questions and Answers 2024 Thirds feed on rose pollen. Scientists noted that the thirds population increased in the spring and decreased dramatically during the summer. The researchers hypothesized that food abundance was the limiting factor for the population. Which type of data would be most useful for the scientists to collect at regular intervals on a designated test plot of rose plants? Density of rose pollen produced (g/m^2) NOT: The amount of pollen produced by each flower Undersea landslides can disrupt marine habitats by burying organisms that live on the ocean floor. The population in the graph was affected by a recent landslide. What is the best prediction on how the population will be affected by the landslide? The reduced population will likely have allelic frequencies that are different from the initial population. NOT: The population will adapt to deeper waters to avoid future landslides. Describe the Calvin Cycle The reactions of the Calvin cycle add carbon to a simple five-carbon molecule called RuBP. These reactions use chemical energy from NADPH and ATP that were produced in the light reactions. The final product of the cycle is glucose. What is apoptosis? Apoptosis involves the regulated activation of proteins in specific cells of the developing forelimb that leads to the death of those cells. "Programmed cell death" What is pre-zygotic isolation? It is a type of reproductive isolation that occurs before the formation of a zygote can take place. In most cases mating does not even occur. The observation that the rabbit mRNA was successfully translated in the frog tissues supports which conclusion? Rabbits and frogs share a common genetic code for expressing heritable information. NOT: Frog cells are able to replace their own hemoglobin with rabbit hemoglobin. Which conclusion is most consistent with the results of the experiment? The subunits of hemoglobin differ in size, shape, or charge. NOT: Rabbit mRNA is composed of nucleotides that are absent from frog mRNA. A student crossed a male Drosophila melanogaster having a gray body and long wings with a female D. melanogaster having a black body and apterous wings. This was the distribution of traits in their offspring: Gray body, long wings; 42 Black body, apterous wings; 41 Gray body, apterous wings; 9
