Factors Limiting Photosynthesis The rate of photosynthesis increases with increasing light intensity. But too much light intensity can slow down the rate of photosynthesis because the light damages chloroplasts in the leaf. The higher the temperature the greater the rate of photosynthesis as photosynthesis is a chemical reaction and chemical reactions increase with temperature. But at temperatures above 40 C the rate slows down because the enzymes involved are destroyed

Mastering Concepts 2.1 1. Which chemical elements do organisms require in large amounts? Carbon‚ oxygen‚ hydrogen‚ nitrogen‚ sulfur‚ and phosphorus are the chemical elements that organisms require in large amounts. 2. Where in an atom are protons‚ neutrons‚ and electrons located? An atom’s protons and neutrons are in its nucleus. A cloud of electrons surrounds the nucleus. 3. What does an element’s atomic number indicate? An atom’s atomic number indicates the number of protons in its nucleus

That made it smooth. Now‚ it is a fine‚ white cellulose powder that can be made into a gel by adding water. Inglett also developed Oatrim. This is made up of a digestible fiber from oat flour that provides four calories per gram. Z-Trim compared to another fat substitute‚ olestra‚ is different. Olestra

organisms are classified as a kingdom‚ Fungi‚ which is separate from plants‚ animals‚ protists and bacteria. One major difference is that fungal cells have cell walls that contain chitin‚ unlike the cell walls of plants and some protists‚ which contain cellulose‚ and unlike the cell walls of bacteria. These and other differences show that the fungi form a single group of related organisms‚ named the Eumycota (true fungi or Eumycetes)‚ that share a common ancestor (is amonophyletic group). This fungal group

History 1945 Epiphone Blackstone archtop guitar‚ made in New York The history of Epiphone started in 1873‚ in Smyrna‚ Ottoman Empire (now İzmir‚ Turkey)‚ where Greek founder Anastasios Stathopoulos made his own fiddles and lutes (oud‚ laouto). Stathopoulos moved to the United States of America in 1903‚ and continued to make his original instruments‚ as well as mandolins‚ from Long Island City in Queens‚ New York. Anastasios died in 1915‚ and his son‚ Epaminondas‚ took over. After two years‚ the

Patterns in Nature 1. Organisms are made of cells that have similar structural characteristics * Outline the historical development of the cell theory‚ in particular the contributions of Robert Hooke and Robert Brown Robert Hooke was the first person to observe a cell through a compound microscope in 1665. Franscesco Redi used a microscope to observe that flies do not spontaneously appear but develop from eggs laid by other flies. Many years later‚ Robert Brown observed a large body in
