The cell is the fundamental structural unit of all living organisms. Some cells are complete organisms‚ such as the unicellular bacteria and protozoa; others‚ such as nerve‚ liver‚ and muscle cells‚ are specialized components of multi-cellular organisms. Cells range in size from the smallest bacteria-like mycoplasmas‚ which are 0.1 micrometer in diameter‚ to the egg yolks of ostriches‚ which are about 8 cm (about 3 in) in diameter. Although they may differ widely in appearance and function‚ all cells

Cells are considered the basic units of life in part because they come in discrete and easily recognizable packages. That’s because all cells are surrounded by a structure called the cell membrane. The cell is the very smallest unit of living matter. All living things including plants and animals are made up of cells. Cells are made of atoms‚ which are the smallest units of matter. There are many different kinds of cells. The two kinds you are most likely to be familiar with are animal and plant

Cell Respiration Respiration is the process by which organisms burn food to produce energy. The starting material of cellular respiration is the sugar glucose‚ which has energy stored in its chemical bonds. You can think of glucose as a kind of cellular piece of coal: chock-full of energy‚ but useless when you want to power a stereo. Just as burning coal produces heat and energy in the form of electricity‚ the chemical processes of respiration convert the energy in glucose into usable form. Adenosine

Chemistry Lab Report (Design) Factors affecting Rates of a Reaction (Kinetics) KINETICS DESIGN LAB Research Question: Does the concentration of Potassium Iodide (KI) affect the rate of its reaction with hydrogen peroxide (H2O2) (of a fixed concentration)? Introduction: There are several factors that affect the rate of a reaction. Some of them being Pressure (if the reactants are Gases)‚ Temperature‚ Presence of a Catalyst‚ Surface Area of the reactant‚ and Concentration. According to

Design lab for the rate of reaction between Mg and H2SO4 Introduction: Increasing the concentration (in moles) of H2SO4 will increase the rate of the reaction when a ribbon of Mg is added to the solution. The rate of the reaction all depends on how strong the concentration of the solution is. Research question: Does altering the concentration of H2SO4 increase the rate of reaction when a ribbon of Mg is mixed with the solution? Variables: Independent Variable: The concentration of

of graphic design made in Switzerland. It became famous through the art of very talented Swiss graphic designers‚ but it emerged in Russia‚ Germany and Netherlands in the 1920’s. This style in art‚ architecture and culture became an ‘international’ style after 1950’s and it was produced by artists all around the globe. Despite that‚ people still refer to it as the Swiss Style or the Swiss Legacy. This progressive‚ radical movement in graphic design is not concerned with the graphic design in Switzerland

Beverly Hearst IB SL Physics Rate of Vaporization Design Lab Research Question: How does changing the surface area of a sample of water affect the time taken for the water to boil? Background: By changing the containers of the water‚ the surface area of the water is thus being modified as the same volume of water is spread out over smaller or larger surfaces. The measure being compared is the time each sample of water will take before it reaches the boiling point‚ 100 C°. The relationship
