The following four questions test your understanding of the principles of relative dating. In the cross section below, intrusion A is an igneous rock formation radiometrically dated at 37 million years, H is a fault, and O and I are unconformities. In the following four questions you are asked to use the principles of relative dating to come to conclusions about the rock layers. Image Description Diagram of several cross-sections. Starting from the top, an F layer runs horizontally across the surface. Beneath the layer F are several other layers going diagonally down across the screen. Four layers meet layer F from below. Starting on the left side of layer F is layer J. To the right of layer J is the unconformity line labeled I. To the right of the unconformity line I is the layer N, K, and B with B being the rightmost layer touching layer F. Going back to the layer J, which is below the unconformity line I, there is a portion of the igneous rock intrusion A in the middle of J. The A intrusion spans from the unconformity line I down to the bottom of the image. To the left of the instrusion A and below the layer J lies layer D and M, with layer M beneath layer D. Beneath layer M lies the unconformity line labeled O. In the middle of the unconformity line O is a fault labeled H. The fault line H runs from line O to the bottom of the screen, offsetting the last four layers C, L, G, and E, with E being the last layer.

A gene that causes various coat patterns in wild and domesticated cats also causes a cross-eyed condition. The cross-eyed condition is slightly maladaptive (makes the cats less successful in the wild). Imagine an environment where one coat pattern is highly adaptive. However, it is also associated with the crossed eyes. The result is that both the coat pattern and the cross-eyed condition increase in a feline population over time. Which statement below accurately describe the example above?

Flower color in snapdragons is due to a gene with incomplete dominance: CRCR plants have red flowers, CRCW have pink flowers, and CWCW plants have white flowers. Which cross is expected to yield progeny that all have pink flowers?

During mRNA splicing, _______ are removed from the RNA transcript, while _______ remain in the RNA transcript and will be translated to proteins.

Please choose 3 of the following statements (A-F) to address. Your answer should explain why it is a misconception and how it can be stated more accurately. Provide at least 2 pieces of evidence to support your answer for each statement you choose.   A) Evolution is just a theory, and a theory is just speculation. B) Evolution is full of “missing links” and there’s no evidence to support it. C) Evolution happens in 1 organism. One fish evolved and grew legs.  The caterpillar evolved into a butterfly. D) Evolution says people came from modern chimpanzees and monkeys. E) Evolution involves small changes and it can’t account for big, complex changes like the evolution of vision.What good is half an eye? F) Evolution always makes things better.

Which of the processes introduces genetic diversity and contribute to the creation of daughter cells that are genetically unique from one another and from the parent cell?

If two males of the same species compete directly with one another over access to a group of females, this is a form of:

8. Assume there is a rating_history table with a column called rating_type that indicates if a movie’s rating is from a regular review, a critic’s review, or an audience award. What question does this correlated query answer? Begin your answer with “This query answers the question: which movies…” SELECT mov_titleFROM movie mWHERE NOT EXISTS (SELECT rh.mov_title                  FROM rating_history rh                  WHERE rh.mov_id = m.id                  AND rh.rating_type = ‘audience award’);

Suppose D is a 4×6 matrix and S is a pxq matrix. Suppose we compute the product DS. What is the number of rows and columns of DS, assuming the product is defined?
