higher resolution and more light‚ you need to put more than one mirror together and make them work together‚” explains Robert Angel‚ a professor of astrology at the University of Arizona (Giant Mirrors to Capture the Universe). Just as we learned in our lab‚ we need a good source of light for something to become clear. The mirrors that are used for the telescope cause the light to be reflected off of one mirror onto the other which then create a clear image from the large convex lens. “Because these

If you are among the millions of Americans who are weighing the pros and cons of landlines vs. cell phones‚ here

Unit 1. Lab 1. Fixed Line vs. Cellular Debate A cellular network or mobile network is a wireless network distributed over land areas called cells‚ each served by at least one fixed-location transceivers known as a cell site or base station. In a cellular network‚ each cell uses a different set of frequencies from neighboring cells‚ to avoid interference and provide guaranteed bandwidth with each cell. When joined together these cells provide radio coverage over a wide geographic area. This enables

Exercise 1: Dissolved oxygen is oxygen that is trapped in a fluid‚ such as water. Since virtually every living organism requires oxygen to survive‚ it is a necessary component of water systems such as streams‚ lakes and rivers in order to support aquatic life. The dissolved oxygen is measure in units of ppm—or parts per million. Examine the data in Table 2 showing the amount of dissolved oxygen present and the number of fish observed in the body of water the sample was taken from; finally‚ answer

In this stimulation the amount of product produced during the course of an enzymatic product produced during the course of an enzymatic reaction will be measured. Hypothesis 1: What is the estimate optimal of ph? Hypothesis 2: What is the estimate optimal of temperature? Hypothesis 3: How does the concentration of enzyme influence the rate of reaction?

Data Analysis: Graph 1 indicates the relationship between the dependent and the independent variable to be; as the concentration of sodium bicarbonate in the solution submerging the leaf discs is increased‚ the average rate of photosynthesis of the leaf discs increased in a linear trend. As it is the sodium bicarbonate which decomposes into carbon dioxide necessary for photosynthesis‚ it is reasonable to consider from Graph 1 that as carbon dioxide concentration of the solution increases‚ the rate
