You are an economist for a major Fortune 1000 firm. Your firm uses a commodity or sells a commodity in the production process (inputs) or its final product. (Clothing maker using Cotton)

Deliverable Paper

Taking on your role, you will write a memorandum to the Production Process Strategic Committee related to your recommendation and strategy on how to address price changes in the major commodity input in your final product

Classify each of the following situations as either "cooperativity" or "allostery":  

1. An insulin binding to a GPCR triggers many conformational changes in the GPCR.

2. Annexins are remodeling proteins with membrane binding affinity that can be increased in the presence of calcium ions.

3. When valium (a narcotic) binds to a GABA receptor, the receptor's affinity for binding to GABA increases.

4. Once phosphorylated, phosphorylase kinase adopts a new structure that is functional.

n cancer cells, chromatin around proto-oncogenes and tumor suppressors is often changed in comparison to cells that are not cancerous. Considering that higher expression of proto-oncogenes and lower expression of tumor suppressors (in comparison to normal cells) could lead to a cancerous phenotype, would you expect that the following changes/differences in chromatin in cells could lead to a cancerous phenotype?

"Higher levels of HATs around proto-oncogenes"

A greenhouse (30’x20’x10’) in Yuma, Arizona needs to be cooled from an outside temperature of 110oF to an indoor 75oF. The RH outside is 4% and the greenhouse requires 5 air changes per hour. Determine the amount of water required per hour to achieve this level of Evaporative cooling. Please state your answer in pounds of water.

A Carnot-cycle refrigerator rejects heat at the pressure of 1000 kPa during which the working fluid R -134a changes from saturated vapor to saturated liquid. The heat is added to the cycle at the pressure of 320 kPa. Show the cycle in a T-s diagram and determine the coefficient of performance of the cycle using a) the first law of thermodynamics b) the Carnot cycle efficiency equation and c) the T-s diagram.

Which of the following affect the internal osmotic pressure of a system, such as a cell?

Group of answer choices

Osmotic pressure increases with a decrease in volume and increases with an increase in concentration.

Osmotic pressure is independent of volume changes.

Osmotic pressure increases with a decrease in volume and decreases with an increase in concentration.

Osmotic pressure decreases with a decrease in volume and decreases with an increase in concentration.

Osmotic pressure decreases with a decrease in volume and increases with an increase in concentration.

The polarization of a helium-neon laser can change with time. The light from a 1.5 mW laser is initially horizontally polarized; as the laser warms up, the light changes to be vertically polarized. Suppose the laser beam passes through a polarizer whose axis is 21 ∘ from horizontal. By what percent does the light intensity transmitted through the polarizer decrease as the laser warms up?

(Iwarm-Icold)/Icold= ? %
