The simplicity and clarity of Caenorhabditis elegans allowed researchers to correct answers Identify the genes in differentiation of each cell type The diffraction limited resolving power of a standard light microscope is approximately correct answers 0.2 Om Chloroplasts are thought to have originated from endosymbiosis of ___ by large host cell. correct answers Photosynthetic eubacteria such as cyanobacteria The eukaryotic nucleus contains ___ DNA molecule (s). correct answers Multiple...

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 ...

Which energy-producing process is thought to have come first during cellular evolution? correct answers Glycolysis The initial importance of a membrane enclosing self-replicating RNA molecules and associated proteins was that it correct answers maintained these molecules as a unit capable of reproduction and evolution. Mitochondria and chloroplasts resemble bacteria in that they correct answers have their own DNA, have their own ribosomes, reproduce by simple division into two. Which of...

In the 1850s and 1860s, Mendel bred pea plants and examined the way that traits were passed down across generations. His conclusions, although not accepted during his lifetime established the foundation for the field of genetics. What is the most relevant summary of these conclusions? The hereditary factors responsible for traits such as shape and flower color are inherited as discrete units. The purple flower of the F1 offspring of Mendel's parental generation crosses indicate that: both a an...

In which location in the genome are transposable elements least likely to experience strong selection? a noncoding area of the genome that experiences little recombination There are 1,200 functional olfactory receptor genes in the mouse genome and only 550 in the human genome. Which of the following is the possible reason? genes that are rarely used can degenerate because of reduced selective pressure Mutations at the third position of the codon are more likely to _____ than mutations at the f...
