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

of homemade materials‚ then it would be possible for it to travel 8 meters powered by a nine inch balloon. Independent Variable: building the car from homemade materials. Dependent Variable: The results of speed and distance from the car responding to the materials Rationale: In this experiment‚ the challenge is to build a balloon powered car from homemade materials that can travel at least 8 meters. According to Newton’s Third law‚ it is possible to accomplish this objective. Force is any push

mitigate the risk (pay attention to polarity!). We give the elements in this circuit some simple values for the purpose of better description and explanation. Say V = 5V‚ R= 1 Ω and L = 1H. Assume inductor is initially uncharged. FIGURE 1 From Figure 1: At t0‚ switch is opened. VL= L (di/dt) . L = 1H di=(Ifinal – Iinitial) = (0 – 5) dt= 0.02s‚ say it takes this amount of time to open the switch. Hence‚ VL = (1) (-5) (0.02) VL = -250 V The electrical potential difference

Evolution Lab Report Marcos Chapa July 3‚ 2013 BIO 101 Rebecca Avants The purpose of the lab I have conducted is to analyze how altering the finch’s environment would affect the evolution of the finches by isolating each population of finches from each other‚ placing them each on a different island. This influence on the species by the environment is called allopatric speciation. One population of the finches that are located Darwin Island‚ which is 1 km‚ and the other population of finches

Bacterial Transformation Lab Report Backround: The plasmid pGLO contains an antibiotic-resistance gene‚ ampR‚ and the GFP gene is regulated by the control region of the ara operon. Ampicillin is an antibiotic that kills E. coli‚ so if E. coli‚ so if E. coli cells contain the ampicillin-resistance gene‚ the cells can survive exposure to ampicillin since the ampicillin-resistance gene encodes an enzyme that inactivates the antibiotic. Thus‚ transformed E. coli cells containing ampicillin-resistance

Introduction In unit 7.3 the experiment tested the ability of lactase to specifically bind and interact with lactose compared to maltose. In unit 7.4 the experiment tested the role‚ if any‚ that metal ions have on the activity of lactase. My hypothesis for unit 7.3 was knowing that lactase is specific for lactose‚ lactose will separate into galactose and glucose‚ as maltose will not change (153-155). Lactase should like lactose. For unit 7.4 my hypothesis was that EDTA will remove the ions‚ and
