Startle reaction

This photo is a picture of my lofted bed next to a large two-paned window. This is just one of two windows in my dorm room in De Smet Hall. The concept that I will discuss regarding my photo is thermodynamics and transfer of heat. Specifically, I will be discussing conduction from the temperature outside of De smet and the temperature of my dorm room. The material that the energy will transfer through is the two large two-paned windows that are on each wall. I will complete example calculations…

to conclude that the reaction with the fastest reaction rate is magnesium and hydrochloric acid. Initially, it was hypothesized that the reaction with hydrochloric acid would have the fastest reaction rate due to its high acidity observed from the pH scale. From there, the following reactions were based on the pH of the acid involved as well as the concentration of hydrogen ions/atoms within the acid molecule. As a result, it was hypothesized that the sulfuric acid reaction would be the second…

There are factors that can affect the enzymatic activity. Enzymes are known to speed up the biological reactions. It is specific to its substrate which in this experiment is known to be catechol. The catechol oxidase is used in all parts to express the concentration in the enzyme reacting into ortho-quinone (Schultz, 2006). The catechol oxidase if from the potato that was used in this experiment. The enzyme was extracted as the full strength after centrifugation and used the homogenization as…

Topic: Identifying Unknown Substances. Equipments: • 5 test tubes. • 1 beaker of Acid 1 beaker of water • 4-Litmus papers • 2 Pipette bulbs. • 1 robber stopper. • 1 Bunsen burner. • Q-tips(4). • Scoopula. Observation: Which substance is which? Hypothesis: All the unknown substances that we have are soluble in water. Procedure • We had a 4 test tubes filled with small amount of white powder. We labeled each test tube. For example the first test tube was labeled as “Substance A” , the second…

We are testing different watt light bulbs and how it affects how fast the chads rise. We are using 300, 200, 100 and 60 watt lights bulbs. We are timing how long it takes for the chads to rise with each different light. Photosynthesis is a chemical process through which plants, some bacteria and algae, produce glucose and oxygen from carbon dioxide and water, using only light as a source of energy. Photosynthesis converts massive amount of Sunlight into electrical and then chemical energy. The…

affect reaction time more?”. The hypothesis is : If a meter stick is dropped and caught while texting or talking to test the subject’s reaction time, then texting will have more of a reaction time than talking. This test measures reaction time of texting and talking to know which of the two are more dangerous to multitask with. Texting uses three distractions of the brain, visual, cognitive, and manual while talking just uses manual and cognitive. Texting on the phone had an average reaction…

Lead concentrations can be measured in various body tissues or by measuring the biomarkers of the toxic effects of lead. The concentration of lead in the body has been measured in blood, bone, nails, hair, teeth, urine, faces and saliva for screening and diagnostic purposes. In all samples, specimen collection, storage and processing must be meticulously performed to avoid contamination of the samples with lead in the surrounding environment. Teeth, nail and bone reflect long term exposure to…

For my orthographic drawing, I created three different views of my putt putt boat. I created a top, front and side view of my boat. I created an orthographic drawing because it accurately shows the top, front and side views clearly and more precisely. I was representing a 3d object in 2 dimensions. My three views show how each side of the boat looks in detail and the accurate measurements of the boat. To create the hull, we shaped a piece of aluminum into a “pocket” by using sandpaper to sand…

will affect enzyme function by increasing the reaction rate because as temperature increase so is the rate of reaction and extremely high or low pH will result in the denatured by decreasing the reaction rate. The function of this experiment was to investigate the influence of the concentration of enzyme on the rate of reaction. The rate of reaction in this experiment was subjected by the amount of Guaiacol, H2O2, Extracts, and Buffer (pH5). The reaction rates with different enzyme concentration…

Since the naming of the dinosaurs in 1842 it has been thought that their metabolisms were similar to current day ectothermic, cold blooded reptiles., In the 1960’s- 1970’s; however, it started to become apparent that an endothermic metabolism (warm blooded, like mammals) is more conformable with new evidence and observations. Originally, predictions on the paleothermometry of dinosaurs was based on the physical performance such as the estimation of running speed from trace fossils as well as…
