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= ? %

Consider 50 moles of carbon dioxide in a piston-cylinder that is isothermally compressed at temperature of T=350 K from 100 kPa to 400 kPa. What are the changes in the total entropy (of the Universe), the system, and the surroundings if the gas is compressed using a heat reservoir at a temperature of 350 K? Using a heat reservoir at a temperature of 250 K? You can assume that the processes within the piston-cylinder system are internally reversible.

According to Boyle’s law, for a certain gas, pressure an volume are inversely proportional: P = 800/V where V is measured in and pressure P in pounds per square inch.
a) Find the rate of change of P when V=20 , and interpret its meaning (carefully state the units).
b) Find the average rate of change of P when V changes from 20 to 25 . Compare your result with a).

Given the enormity of secondary data availability, research options have been modified over the years; after conducting some basic search using scholarly articles, briefly outline such changes and how they have affected traditional survey and experimental research. Your response should include sound arguments and examples to further extend the discussion

how can I put in a work cited page for this answer.

Take the perspective of the CEO of a large healthcare system that owns its own managed care health plan. Describe three major ways that you could improve the quality of healthcare in your organization. Critique your solutions regarding the extent to which your solution may cause other problems to surface [what kind?], and the extent to which you as the CEO should have the responsibility and power to implement these changes.
