Energy Lab On November 13th‚ we did a lab to learn about energy. The definition of Kinetic Energy is energy of movement. The definition of Gravitational Potential Energy is energy in an object due to its positioning. The question that we had to answer was whether of not we could calculate the Gravitational Potential Energy and Kinetic Energy of various objects in different locations. To do this lab we had to first weigh the given objects. For this time‚ we weighed : a marble‚ a bouncy ball‚

Calcium‚ Magnesium‚ and Cytoplasmic Streaming in Physarum Polycephalum Eugenia Rita Lee Dr. Bonner BIO 111 Introduction: Physarum polycephalum is a type of slime mold of the myxogastria class that prefers warm and damp conditions. It can go through three forms‚ plasmodium‚ sclerotium‚ and sporangia. The plasmodium is the primary active state‚ where P. polycephalum consists of protoplasmic veins and multiple nuclei. During this stage‚ the slime mold surrounds its’ food and secretes enzymes

Magnesium: Normal Ranges: 1.7 to 2.2 mg/dL A magnesium test is used to measure the level of magnesium in the blood. Abnormal levels of magnesium are most frequently seen in conditions or diseases that cause impaired or excessive excretion of magnesium by the kidneys or that cause impaired absorption in the intestines. Magnesium levels may be checked as part of an evaluation of the severity of kidney problems and/or of uncontrolled diabetes and may help in the diagnosis of gastrointestinal disorders

Chemistry 121 Colligative Properties Lab Demonstration of Selected Calculations from Choice I Determination of Kf for Naphthalene To determine the Kf for naphthalene‚ we need to find the difference in the freezing point of pure naphthalene and the solution of 1‚4-dichlorobenzene in naphthalene. Let’s say that we did this experiment‚ used 1.00 g 1‚4-dichlorobenzene in 10.00 g naphthalene‚ and found that the freezing temperature of pure naphthalene was 78.2°C‚ while that of the solution was 75
