Some students measured the pH of water containing elodea‚ a common water plant. The students wanted to learn how much carbon dioxide elodea removes from the water. The students knew that decreasing levels of carbon dioxide correspond to increasing pH. Which cellular structure in elodea carries out the process that is most likely to result in increasing pH? Which structures‚ if found in a cell‚ would provide the best evidence that the cell is eukaryotic? Where in the cell do the following

I turned this paper in two days late‚ but the teacher was so impressed that I still got 100% Excellent; I couldn’ t have written a better paper myself. DIVERSITY OF PLANTS Plants evolved more than 430 million years ago from multicellular green algae. By 300 million years ago‚ trees had evolved and formed forests‚ within which the diversification of vertebrates‚ insects‚ and fungi occurred. Roughly 266‚000 species of plants are now living. The two major groups of plants are the bryophytes and the

Copper is an element that occurs in minor amounts in the earth’s crust. Estimates of average crustal prevalence are on the order of 0.0058 percent by weight. Deposits considered to be economically recoverable at current market prices may contain as little as 0.5 percent of copper or less‚ depending on the mining method‚ total reserves‚ and the geologic setting of the deposit. Here is the flow sheet on how to process copper from Zenith. Copper Process Flow Sheet: Copper ore is first quarried from

Separation Lab Purpose: This lab was based on the separation of the components of a mixture. A mixture can be defined as a physical combination of two or more pure substances. Separation techniques are used to separate components that are not chemically combined. All of these techniques involve changes in the physical state of a chemical compound rather than chemical changes. Sea sand‚ table salt‚ and two other unknown substances will be separated using the separation techniques in order to demonstrate

34B Frog cardiovascular Physiology: computer simulation 1. What was the baseline heart rate for the frog? Ans: 59-63 bpm 2. Which wave is larger‚ the one for atrial constriction or the one for ventricular contraction? Why Ans: Ventricular. It shows the strength of the ventricle as it pumps blood‚ and it is a thicker muscle to pump stronger as it contracts 3. At what time during the contraction cycle was it possible to induce an extrasystole? Ans: The time during the relaxation part of

Regina May P. Hinagdanan 10-SCB Physics Reaction Paper Is nuclear power plant really that dangerous? It is true that many people have varying opinions about having nuclear power plants and developing nuclear energy. I‚ myself‚ see it as a good alternative source of energy while my brother sees it as a weapon for mass destruction. Nowadays‚ people are easily swayed by the reports of the media. Indeed‚ most of them are true but some of them tend to be a bit exaggerated. The article pointed

Gas Chromatography: Purifying alcohol Introduction The goal of this lab is to understand the principles of chromatography by purifying alcohol using fractional distillation. Running standards with gas chromatography we were able to see and calibrate our data to find not only how much ethanol our alcohol attained but also what a mixed unknown sample contained. Chromatography is a way of being able to separate substances in solution that can help not only identify the analytes (the studied

[pic] Good planning is central to successful teaching - and effective planning requires a clear set of learning objectives. In order to generate learning objectives‚ you need first to check the syllabus requirements. These may be expressed in a variety of ways. For example‚ they may be given as topic headings‚ or learning outcomes‚ or competence statements. The precise form varies according to the type of qualification. In order to understand the uses and characteristics of learning objectives
