# Now You See It – Copper Cycle Lab The purpose of the lab is to discover what happens when someone executes a series of procedures‚ beginning with copper metal. What is done | What is observed | 1. Started with copper‚ Cu (s). | reddish‚ brownish‚ orange-ish‚ powder-like | 2. Added nitric acid‚ HNO3 (aq). | acid turns blue and smells like chlorine. | 3. Added water‚ H2O (l). | stayed the same | 4. Added sodium hydroxide‚ NaOH (aq). | changed consistency‚ gel-like | 5. Heated the

see his reflection. We also exposed the fish to many others to see if the behavior was the same or different when placed next to: a goldfish‚ a female Betta fish‚ and a zebra fish. My hypothesis was supposed by this experiment and it was observed that the Betta fish was disturbed by his reflection in the mirror but his aggressive behavior decreased rapidly when other tanks‚ containing different types of fish‚ were placed next to his. Introduction Ethology is the study of animal behavior

Purpose: To find how pH and temperature levels affect the enzyme Background: Enzymes are a type of protein vital to sustaining life‚ it works with vitamins and minerals as a biological catalyst‚ which lowers the activation energy for a reaction to occur. Each individual type of enzyme does a specific job‚ and they do not die‚ they are reused. For example‚ catalase is an enzyme found in almost all living cells that will break down hydrogen peroxide and turn it into water and oxygen. The

diseases (Labbe et al.‚ 2008). Also‚ many drugs produced contain drug classes that can inhibit the function of mitochondria by preventing or altering a stage in ATP production in the Krebs cycle or electron transport chain or acting as an inhibitor of an enzyme that carries out a certain reaction in citric acid cycle or ETC (Dykens and Will‚ 2007). These drugs are therefore pretested

This lab specifically does not require the knowledge of what each organism does when introduced to another living organism‚ like a human. Figuring out the type of bacteria could help with further experiments. The idea of the unknown bacteria lab is to show

lipase‚ an enzyme that breaks down fat. The fat hydrolysis test was positive‚ showing K. pneumoniae produces lipase and can break down fats. The indole test was performed to determine if our bacteria can break down tryptophan via the enzyme tryptophanase. Our indole test came back negative‚ meaning K. pneumoniae does not produce tryptophanase and does not break down tryptophan into indole‚ ammonia‚ and pyruvic acid. The urea test was performed to determine if urea is hydrolyzed via the enzyme urease

It was hypothesized that if the animal was larger‚ then it would have larger hemoglobin. It was thought that larger mammals would need more oxygen-rich hemoglobin to support healthy function. This lab did not support this hypothesis. The results in table 1 displayed that the hemoglobin of all mammalian samples traveled about the same distance. This trend can be seen in graph 1 as the mammalian hemoglobin samples migrated the same distance. Because the proteins traveled around the same distance it

PEES 4200W- Physiology of Exercise Lab #2: Metabolism and Energy Expenditure 1. The Respiratory exchange ratio is the ratio of the volume of carbon dioxide produced and oxygen consumed. The ratio indicates the energy that the subject is expending for indirect calorimetry‚ how efficient the subject ’s body is at utilizing the oxygen inhaled‚ as well as the main substrate being used for energy during varying intensities of exercise. During rest the volume of carbon dioxide was 0.73L/min‚ the volume

wouldn’t go as far and the direction or trajectory of the cannon ball would be a curved line going down. Purpose: The purpose of this lab is to give the student a better understanding about projectile motion and to understand Newtons theories and laws of motion. We will be firing the plastic ball from the projectile launcher three times from eight different angles from the ground & a stool. With this experiment we will see if shooting from the ground gets the plastic ball to travel farther
