    Meal Worm Cellular Respiration Experiment Introduction Cellular respiration provides energy to all living organisms by collecting energy from food molecules. The cell then rearranges complex molecules to simpler molecules and uses that energy to make a molecule that stores energy called adenosine triphosphate also known as ATP. Cellular respiration can occur with or without oxygen. When it occurs without oxygen‚ it is called anaerobic respiration. There are very few organisms that can get

    Potato Osmosis Biology SL - ATh INVESTIGATION “Potato Osmosis” INTRODUCTION Osmosis is a process that occurs at a cellular level that entails the spontaneous net movement of water through a semi-permeable membrane from a region of low solute concentration to an area of high solute concentration in order to equalize the level of water in each region. Involved in this process are hypotonic‚ hypertonic and isotonic solutions. A hypotonic solution is one with a lower osmotic pressure‚ indicating

    Chapter 12 (Part 2) Explain the principle of independent assortment and its relation to meiosis: The segregation of chromosomes in anaphase I of meiosis explains Mendel’s observation that each parent gives one allele for each trait at random to each offspring‚ regardless of whether the allele is expressed. The segregation of chromosomes at random during anaphase I explains Mendel’s observation that factors‚ or genes‚ for different traits are inherited independently of each other. Apply the

    Part 2: Safe work with large inductances 1. One of the main hazards of using inductances is electrical energy stored in the magnetic field. If a circuit containing an inductance is interrupted then the stored energy can release through air (forming an arc). This can destroy a switch contact‚ burn fingers‚ create other damage. In the circuit of Figure 1‚ show how to mitigate the risk (pay attention to polarity!). We give the elements in this circuit some simple values for the purpose of

    Experiment 4: Qualitative Analysis of Cations and Precipitation Reactions The overall goal of experiment four was to determine the identity of unknown cations presented to the student. But in order to know the identity of these unknowns‚ in part 1‚ Ag+‚ Pb+‚ and Hg22+ were presented to the student in aqueous solutions and then precipitated through experimentation. In part 2‚ the same procedure was enacted to determine which substances precipitated through qualitative analysis. Solubility rules

    experiment was to perform a reduction reaction on the ketone group of camphor to the OH group on isoborneol. In order to successfully synthesis the reactant to the product‚ NaBH4 was used as the main reagent to reduce the carbonyl double bond. One believes the formation of isoborneol was successfully due to the product’s percent yield‚ IR‚ and melting point. During the lab‚ .077 grams of isoborneol was yielded from the camphor reduction. In result‚ .077 g compared to an theoretical yield of .102 g equaled

    Do you know what Potassium cyanide is‚ what it does to your body‚ and what its use is? This paper will answer all those questions‚ and will specifically examine how potassium cyanide affects the body and how it is used. Potassium cyanide is a white crystalline salt solid that has a faint‚ bitter-almond like smell. It’s empirical formula is KCN. The taste of KCN is described as burning the tongue and tasting acrid. This compound deliquescent‚which means that it tends to dissolve. The appearance is
