Evolution 2019 Practice Questions1.Five new species of bacteria were discovered in Antarctic ice core samples. The nucleotide (base)sequences of rRNA subunits were determined for the new species. The table below shows thenumber of nucleotide differences between the species.Which of the following phylogenetic trees is most consistent with the data?AAP BiologyNameCopyright © 2019.

The graphs below illustrate fourpossible changes to the beetle population as a result of a change in the environment due to pollutionthat darkened the tree trunks.Which of the following includes the most likely change in the coloration of the beetle population afterpollution and a correct rationale for the change?B The data in the graph best support which of the following claims?(A) Environmental contamination elevates total testosterone oxido-reductase activity infemales.(B) Environmental contamination reduces total testosterone oxido-reductase activity infemales.(C) Environmental contamination elevates total testosterone oxido-reductase activity inmales.(D)Environmental contamination reduces total testosterone oxido-reductase activity inmales. 11.In a hypothetical population of beetles, there is a wide variety of color, matching the rangeof coloration of the tree trunks on which the beetles hide from predators. The graphsbelow illustrate four possible changes to the beetle population as a result of a change inthe environment due to pollution that darkened the tree trunks.Which of the following includes the most likely change in the coloration of the beetlepopulation after pollution and a correct rationale for the change? SHORT ESSAY12.(8 points) In eukaryotic cells, ribosomes are found both free in the cytosol and attached tothe endoplasmic reticulum (ER). Proteins produced on the attached ribosomes travelthrough the endomembrane system, with many ultimately secreted from the cell; proteinsproduced on free ribosomes are delivered to the cytosol (or stored in plant vacuoles).(A)Briefly explainthe following in 2-4 sentences each.(B) Describe the endomembrane system.(C) Why do proteins made at the rough ER get molecular zip code while those made atfree ribosomes do not?(D)What is the importance of receiving a molecular zip code?(E) Using the previous responses, what is the purpose of the endomembrane system?13.(3 points) Describe the endosymbiosis theory. Provide 2 examples of evidence that supportthe theory. Newly uploaded documentsRecommended textbook solutions Biology1st EditionKenneth R.

The coloration in the population shifted toward more darker-colored beetles, as in diagram IV.
Which of the following best explains the change in the frequency distribution of fur color phenotypes in the mouse population as shown in the figure above?Which of the following best explains the change in the frequency distribution of fur color phenotypes in the mouse population, as shown in the figures above? The field was composed primarily of light-colored soil and little vegetation, affording gray mice protection from predators.

Energy input from light is required for the grass to grow and maintain an ordered structure.
Which of the following best explains the observations concerning DDT resistance in mosquitoes?Which of the following best explains the observation concerning DDT resistance in mosquitoes? natural selection favors DDT- resistant mosquitoes that are already present in a population when DDT exposure occurs.
