Bio 104-03 Lab #3- Acids Bases‚ and Buffers 1. An acid is a substance that releases hydrogen ions as they desolve in water and ranks lower than seven on the pH scale. An example of an acidic substance is lemon juice. A base is a substance that accepts hydrogen ions and ranks higher than seven on the pH scale. An example of a base substance is hand soap. A neutral substance ranks a seven on the pH scale and has equal concentrations of H+ and OH-. An example of this is pure water. Electrolytes

Mitosis Under Microscope Lab Report A. The purpose of the investigation is to determine the time an onion cell spends in each part of the cell cycle. B. The significance of this investigation is to help us understand and know how long cells are undergoing mitosis. My personal interest is to know the phases of mitosis in cells in order to someday help find cures for cancer. C. The cell cycle is a chronological set of events‚ culminating in cell growth and division into two daughter cells. Some

MITOSIS The Stages of Mitosis Mitosis is simply described as having four stages—prophase‚ metaphase‚ anaphase‚ and telophase; the steps follow one another without interruption. The entire four-stage division process averages about one hour in duration‚ and the period between cell divisions‚ called interphase or interkinesis‚ varies greatly but is considerably longer. During INTERPHASE the chromosomes are dispersed in the nucleus and appear as a network of long‚ thin threads or filaments‚ called the

DOLP- Fungi General Structure and Function: For many years‚ fungi were classified into the plantae kingdom because the two kingdoms seemed to be alike; but now‚ we know that they are all too different. In fact‚ the fungi kingdom is more closely related to the animalia kingdom. Some of the only notable similarities between the fungi and plantae kingdoms are that they are both made of eukaryotic cells‚ both immobile‚ both contain cell walls (although made of different material)‚ and both evolved

Part I - Introduction Enzymes are proteins that act as catalysts to regulate metabolism by selectively speeding up chemical reactions in the cell without being consumed during the process. During the catalytic action‚ the enzyme binds to the substrate – the reactant enzyme acts on – and forms an enzyme-substrate complex to convert the substrate into the product. Each type of enzyme combines with its specific substrate‚ which is recognized by the shape. In the enzymatic reaction‚ the initial rate
