Chordates are characterized by having a dorsal hollow nerve chord, a notochord, and a tail. Some years ago, researchers discovered that in Tunicates, a single mutation in one gene caused the nerve chord, the notochord, and the tail to all disappear. A writer for Science magazine concluded from this that all three definitive chordate traits must have evolved at the same time, with the appearance of this gene. Explain the flaw in this reasoning.

When 1.95 grams of Co(NO3)2 is dissolved in 0.750 L of 0.220 M KOH, what are the [Co 2+], [Co(OH)4 2-], and [OH-] if Kf of Co(OH)4 2- = 5.00x10^9?

Write a Python program that takes information from the user about a spider seen in North America and returns whether it is likely to be a dangerous spider. The only two spiders in North America that are actually dangerous are the widow and recluse. The program will ask the user for the following information: color and special markings.

printWelcome – prints program information

printColorMenu – Color menu options should be brown, black, other

printSpecialMarkingsMenu – Special markings options should be hour glass on underside, violin shape on head, other

main – takes in color option and returns spider information as follows:

• Brown and hourglass on underside: brown widow is dangerous
• Black and hourglass on underside: black widow is dangerous
• Brown and violin shape on head: brown recluse is dangerous
• Other selected for color or special markings: likely not dangerous

"Cultural Relativism and Human Rights" Please respond to the following: In King’s speech, he claimed: “America has defaulted on this promissory note insofar as her citizens of color are concerned.” Then proclaimed: “So we have come to cash this check…” Most people recognize that he was not talking about money, but he was talking about certain human rights that should be granted to all U.S. citizens. Discuss at least two of those rights and comment on the extent to which you believe those rights have been provided for citizens of color in today’s America. Provide reasons and examples to support your view. Most people who have heard or read this speech agree that it is eloquent, passionate, and persuasive. Could a moral relativist have been as eloquent and persuasive? Provide a rationale for your views.

A Foreign currency trader at the bank’s FX desk calls to inform you that Bank of America is quoting $1.12/€1, and Citibank is offering $1.28/£1. The trader also noticed that Credit Agricole is making market in pound sterling and Euro at €1.18/£1.

a. What is the implied €/£ cross-rate for the two European currencies? Show this trader how you would use $1 million to conduct a triangular arbitrage to profit from the deviation (if any) of the implied cross rate of the €/£, from the rate quoted by Credit Agricole.

b. Suppose you observed that the 3-month forward rate quote from Bank of America is $1.21/€1, calculate the forward premium (discount) implied by the quote.

c. What do investors expect to happen to the value dollar in the next three months?
