A 4-month old baby is admitted to the hospital with a fever of 104o F (compared to a normal temperature of 98.6o F) and a decreased blood pH. Why is it critical to reduce this fever as quickly as possible and restore normal pH? Discuss the role and sensitivity of proteins in (1) normal body chemical processes and (2) how enzyme activity is directly affected by changes in pH or temperature.

Assume you have a suspension of photosynthetic cells carrying out C3 photosynthesis in the presence of 1000 ppm carbon dioxide (0.1%) and 20% oxygen. What effect would the following changes in conditions have on the levels of G3P being produced? Explain your reasoning.               

a) Carbon dioxide concentration is suddenly reduced 1000-fold.                                               

b) Light is suddenly switched off.

Thermodynamics

Air at 3.5 MPa and 500°C is expanded in an adiabatic gas turbine to 0.2 MPa. Assume that the process is reversible. Changes in KE and PE may be neglected and the average temperature of the gases is 550 K.

(a) Create a schematic representation of the equipment. (b) Represent the process on a T-s diagram. (c) Determine the polytropic exponent. (d) Determine the change in entropy for this expansion process

1. Describing the shape and nature of a distribution of scores is a basic skill any researcher needs to inform a lay audience. Changes in skewness and Kurtosis can happen with particular kinds of data. Give an example of what could happen during data collection that can create each kind of change from a standard normal curve that is listed below.

• A positively skewed distribution:
• A Leptokurtic distribution:

Prepare a 100 - 200  word devotional entry responding to these questions.

1. In what phase of the financial life cycle are you (self-preservation, accumulation, or distribution)?

2. How do you feel God would like you to reallocate His resources? What changes can you make to better align your financial decisions with God’s plans for your life?

A refrigeration system contains an adiabatic compressor with Refrigerant-134a as working fluid. Inlet conditions (state 1) are 140 kPa and -100C and the exit state is 1.6 MPa and 800C (state 2). The changes in KE and PE are negligible. Determine (a) actual exit specific enthalpy in kJ/kg, (b) exit specific isentropic entropy in kJ/lg.K and (c) efficiency of the compressor in %.

Suppose that XTel currently is selling at $50 per share. You buy 500 shares using $15,000 of your own money, borrowing the remainder of the purchase price from your broker. The rate on the margin loan is 10%. What is the percentage increase in the net worth of your brokerage account if the price of XTel immediately changes to (i) $55; (ii) $50; (iii) $45?
