3. Nucleotide synthesis a. Wild-type E. coli cells can synthesize all 20 common amino acids, but some mutants, called amino acid auxotrophs, are unable to synthesize a specific amino acid and require its addition to the culture medium for optimal growth. Consider the three amino acid auxotrophs that are unable to synthesize glycine, glutamine, or aspartate. Which ribonucleotide(s) would not be synthesized in each of these auxotrophs? (ATP, СТР, GTP, UTP)? b. Lesch-Nyhan syndrome is a deficiency in hypoxanthine-guanine phosphoribosyl transferase (HGPRT), a key enzyme in the salvage pathway for purines. It allows the bases hypoxanthine and guanine to be reformed into IMP and GMP, respectively. i. One of the consequences of this syndrome is a decrease in GMP and the accumulation of PRPP. How does each affect purine synthesis? ii. Another consequence of Lesch-Nyhan syndrome is the accumulation of excessive amounts of uric acid, like in gout. Why is this the case? How could allopurinol (shown) moderate high uric acid production? HN N

A value-driven car manufacturer, Metlock, started its business more than 50 years ago, making and selling a sedan body style. Sedans were popular at the time, and this one drove the success of Metlock for years due to its practical yet stylish nature. As times changed, Metlock designed models in different body styles, and those models have outpaced sedans, as follows. Sedan SUV Truck Van Sales $1,200,000 $4,194,000 $3,873,000 $2,004,000 Variable costs 696,000 2,010,000 1,808,000 1,102,000 Contribution margin 504,000 2,184,000 2,065,000 902,000 Fixed costs 806,400 895,000 1,205,000 798,000 Operating income (loss) $(302,400) $1,289,000 $860,000 $104,000 The income statements above reflect the second consecutive year the sedan category has lost money. Metlock is concerned about dropping this vehicle, however, since the company's success was originally built on it. (a) Metlock believes it can save $604,800 in fixed costs associated with the sedans if it drops that vehicle category. Should the company seriously consider dropping it? How much better or worse off, financially, would it be by dropping the sedan? Metlock would be by $

Texts: Determine how much to invest in this new online candy company. Since this is a fictional company, there are no 10-K reports available. Therefore, you will have to decide on a fictional amount to invest. Use the accounting methods and principles from the Financial Accounting Standards Board (FASB) Accounting Standards Codification and Generally Accepted Accounting Principles (GAAP), linked in the Supporting Materials section, to apply the correct method to the given acquisition and to summarize basic journal entries based on the amount invested. Journal Entries: Summarize the basic journal entries needed for the current period (at the time of investment) and end of year if 15% of Online Confections of a Chocoholic was purchased. Include the following details in your response: - State the exact dollar amount of the investment. - Note the accounts that should be used in the journal entries. - Use debits and credits appropriately. Summarize the basic journal entries needed for the current period (at the time of investment) and end of year if 33.3% of Online Confections of a Chocoholic was purchased. Include the following details in your response: - State the exact dollar amount of the investment. - Note the accounts that should be used in the journal entries. - Use debits and credits appropriately.

Problem 4 A parabolic coordinate ($\xi$, $\eta$, $\varphi$), which is orthogonal, has the following relation with the Cartesian coordinate ($x$, $y$, $z$) $x = \xi\eta\cos\varphi$, $y = \xi\eta\sin\varphi$, $z = \frac{1}{2}(\eta^2 - \xi^2)$. a) Evaluate the scale factors $h_{\xi}$, $h_{\eta}$, $h_{\varphi}$, which is defined in the line elements $ds^2 = h_{\xi}^2d\xi^2 + h_{\eta}^2d\eta^2 + h_{\varphi}^2d\varphi^2$. (Hint : $ds^2 = g_{ij}dx^idx^j = g_{ij}\frac{\partial x^i}{\partial q^a}\frac{\partial x^j}{\partial q^b}dq^adq^b = g_{ab}dq^adq^b$, where $x^i = (x, y, z)$, $g_{ij} = \delta_{ij}$ and $q^a = (\xi, \eta, \varphi)$. From this one can compute $g_{ab}$.) b) What is the volume element? c) Write down the general expression explicitly for the gradient of a scalar field $\Phi(\xi, \eta, \varphi)$ in this parabolic coordinate, whose unit vectors are ($\hat{\xi}$, $\hat{\eta}$, $\hat{\varphi}$). (Hint : the gradient formula is given by) (4 points) $\nabla\Phi = \sum_{a=\xi, \eta, \varphi} \hat{a}\frac{1}{h_a}\frac{\partial}{\partial q^a}\Phi$.

Use an addition or subtraction formula to write \frac{\tan 12^\circ + \tan 31^\circ}{1 - \tan 12^\circ \tan 31^\circ} as a trigonometric function of one number. You must enter your answer as a degree converted to radians. In otherwords, if your answer is $\sin(2^\circ)$, then you must enter $\sin(2\pi/180)$
