Answer:
Photovoltaic (PV) systems convert sunlight directly to electricity by means of PV cells made of semiconductor materials. Concentrating solar power (CSP) systems concentrate the sun's energy using reflective devices such as troughs or mirror panels to produce heat that is then used to generate electricity.

Answer:Objective: To determine the combined effect of oxygen level and glucose concentration on cell viability, ATP production, and matrix synthesis of temporomandibular joint (TMJ) disc cells.
Design: TMJ disc cells were isolated from pigs aged 6-8 months and cultured in a monolayer. Cell cultures were preconditioned for 48 h with 0, 1.5, 5, or 25 mM glucose DMEM under 1%, 5%, 10%, or 21% O2 level, respectively. The cell viability was measured using the WST-1 assay. ATP production was determined using the Luciferin-Luciferase assay. Collagen and proteoglycan synthesis were determined by measuring the incorporation of [2, 3-(3)H] proline and [(35)S] sulfate into the cells, respectively.
Results: TMJ disc cell viability significantly decreased (P < 0.0001) without glucose. With glucose present, decreased oxygen levels significantly increased viability (P < 0.0001), while a decrease in glucose concentration significantly decreased viability (P < 0.0001). With glucose present, decreasing oxygen levels significantly reduced ATP production (P < 0.0001) and matrix synthesis (P < 0.0001). A decreased glucose concentration significantly decreased collagen synthesis (P < 0.0001). The interaction between glucose and oxygen was significant in regards to cell viability (P < 0.0001), ATP production (P = 0.00015), and collagen (P = 0.0002) and proteoglycan synthesis (P < 0.0001).
Conclusions: Although both glucose and oxygen are important, glucose is the limiting nutrient for TMJ disc cell survival. At low oxygen levels, the production of ATP, collagen, and proteoglycan are severely inhibited. These results suggest that steeper nutrient gradients may exist in the TMJ disc and it may be vulnerable to pathological events that impede nutrient supply.

A country, Azania, has a population of 150 million of which 16 percent is under 16 years old and 18 percent is considered not be in labor force. If 95 million are employed, calculate (a) the employment rate and (b) the unemployment rate. Show all steps.
Answer:
Explanation:
Employement rate = employed people /total labor force * 100
total labor force = 100 - 18% of population not in labor force = 72 = 0.72 *150million = 108 =million
employment rate = [tex]\frac{95}{108} *100 = 87.96%\\[/tex]
umployment rate = unemployed people /total labor force = 100 - 87,96 = 12.04%

Technology from 1900 to 1945
Recent history is notoriously difficult to write, because of the mass of material and the problem of distinguishing the significant from the insignificant among events that have virtually the power of contemporary experience. In respect to the recent history of technology, however, one fact stands out clearly: despite the immense achievements of technology by 1900, the following decades witnessed more advance over a wide range of activities than the whole of previously recorded history. The airplane, the rocket and interplanetary probes, electronics, atomic power, antibiotics, insecticides, and a host of new materials have all been invented and developed to create an unparalleled social situation, full of possibilities and dangers, which would have been virtually unimaginable before the present century.
Which one of these is the hardest to scratch?
Sandstone
Soapstone

Granite

Well the top three hardest are Diamond, Sapphire and Ruby, and an easy way to remember is: red-white & blue stones! The hardness of a gemstone is measured on its place on Mohs scale of hardness. 10 on Mohs scale being the hardest known naturally occurring substance– and the honor goes to the diamond
Although the hardest natural stone on the planet is a diamond that is rated ten on the Mohs scale, granite is known as the most durable and hardest natural stone that is used in construction material and is measured six on Mohs scale.
The hardest mineral commonly found in granite is quartz, which is normally a somewhat translucent, white to grey colored mineral.

Answer:
Karl Marx views on societal development will require my father to put in so much by virtue of production demand and receive so much by virtue of group domination.
Explanation:
My family will be expected to offer my father for regular contributions on societal development as a result of his profession thereby making hi less available to family. While by group domination, he will be expected to benefit less by having to sacrifice more for the needs of those who do not have.

Analyze the extent the conservative Reagan changed the economic and social policies of the United States from 1980 to 2008.
Answer:
Ronald Wilson Reagan (February 6, 1911 – June 5, 2004) was an Hollywood actor and union leader before serving as the 33rd governor of California from 1967 to 1975. He later became the 40th president of the United States from Jan 20, 1981 to Jan 20, 1989 and was highly influential as voice of modern conservatism.
During his terms, Reagan new political and economic initiatives. His economic policies, was termed "Reaganomics", he advocated tax rate reduction to spur economic growth, economic deregulation, and reduction in government spending. Over his two terms, the economy saw a reduction of inflation from 12.5% to 4.4% and an average real GDP annual growth of 3.4% but increased military spending, which contributed to increased federal debt overall.
Reaganomics produces some multiplier effect on economic growth in such that income tax cuts give workers more incentive to work and increased the supply of labor. Not until 2008, when American economy enters recession which led many Americans to loose their job, Reaganomics was known to be one the best economic policy in the history of America.

A Company holds a monopoly of selling shoes. What effect doe the monopoly have on the customer A) The prices are higher B) The prices are lower C) Supply decreases D) Supply Increases
Answer:
C!
Explanation:
The answer is C.
Answer:
A) The prices are higher.
C) Supply decreases
Explanation:
I'm not sure if this question is supposed to have two answers? I believe both A and C could apply to the situation, however.
A monopoly exists when a specific person or enterprise is the only supplier of a particular good. This means that the supply of that good would decrease, due to the fact there is only one supplier. Because of the decrease in supply and the lack of competition, it also means the prices of the good would be higher than if there were multiple suppliers.
