Insulin signaling through its receptor kinase enables virtually every cell in our body to transport glucose across the cell membrane into the cytosol. In the next set of questions, select the appropriate event in the cellular response to insulin.   Activated proteins in the nucleus that cause transcription (and eventually translation in the cytosol) of proteins needed for cell division is an example of:  

Answer the following about how primary sex determination is achieved. 1. What are the two cell populations that comprise the bipotential gonads, and where does each cell population originate from in mammals? 2. How is the initial molecular choice normally made between ovaries or testes, and in which cell population is the decision initiated? 3. Which molecular pathways become activated in ovaries, what differentiated cell populations form in response, and what duct system persists? 4. Which molecular pathways become activated in testes, what differentiated cell populations form in response, and what duct system persists?  

Argument Evaluation First, say how strong the support relation is between the premises and conclusion. Second, explain why the support relation has the strength (or lack thereof) that it has.  If the support is weak and the argument is fallacious, say what fallacy is involved and explain why that fallacy is being committed.     (P1)    We don’t have any reason to suspect that Sylvester dislikes coffee. (C)     So he probably likes coffee.

Fill in the Blanks   Trials on a chance setup are __________________ if and only if the probabilities of the outcomes of a trial are not influenced by the outcomes of previous trials.

Refer to the optimization problem below.     Below are some key information from the answer report and sensitivity report for the optimal solution.     If you want to know how much of a resource went unused in the optimal solution, which value should you refer to?

Probabilistic Reasoning Suppose you have a standard deck of 52 cards, and suppose that it is well-shuffled.  Also suppose that you are drawing cards without replacement (i.e., when you draw a card, you do not put it back into the deck before drawing the next one).  (A standard deck of cards is composed of four suits—two black (spades and clubs) and two red (hearts and diamonds)—each containing one each of the following: ace, 2, 3, 4, 5, 6, 7, 8, 9, 10, Jack, Queen, and King.)   What is the probability that you draw a red card or a 3 on your first draw? 

Fill in the Blanks   A chance setup is __________________ if and only if the relative frequency in the long run of each outcome is equal to that of any other.
