Marjolijn Hoogevoorst Yeshvanth Prabakar IS12 Word count: 2222 words Introduction: Enzymes are biological catalysts that speed up reactions by lowering the activation energy. Amylase is a type of digestive enzyme found in the pancreases and saliva of humans. Amylase breaks down starch into sugar, allowing large molecules to be digested easily. To function efficiently, amylase requires certain conditions. The effect of different sodium chloride concentrations in this on the rate of reaction

In this lab, a series of methodologies were used to determine amylase concentration and gene copy number in order to determine if enzyme production, gene copies and gene evolution were associated (Tracey 2018). Using the equation generated from lab 3, individuals were able to calculate their unique amylase concentrations. However, the calibration curves and equations were unique to each student, rather than a universal equation for each student to use. Each student’s performance of generating the

The University of Houston’s College of Optometry is leading the charge in the fight against myopia, with several studies aimed at discovering how to fully stop the progression of the condition in children — a problem that can lead to permanent blindness. Myopia exists when the eye grows too long on its axial length, Smith said, so light from a faraway object focuses in front of the retina, rather than on it. This causes objects at large distances to look blurry. The myopia epidemic is likely caused

The purpose of this lab was to assess any correlation between the AMY1 gene copy number and amylase concentration, as well as assess the relationship between amylase concentration and average starch consumption in ancestral diet. I had hypothesized that due to my South Asian descent I would have a moderate number of AMY1 gene copies and a moderate salivary amylase concentration. This hypothesis was based on the data presented by the Perry et al paper Diet and the evolution of the human amylase gene

1. What is the purpose of using salt? 1The purpose of using salt is to help DNA stick together, so that we see clumps of tangled DNA molecules. 2. What is the purpose of using the blender? 1The blender separates the cells (of the onion or liver) from each other, so that there is a really thin soup-like liquid of cells. 3. What happens when you add the soap? 1When soap is added it breaks through the cell membrane and the nucleus. 4. What is the purpose of the alcohol? Why does DNA rise to the

Cell Respiration Lab Research Question What is the optimal temperature for germinating pea-seeds where the rate of respiration is the greatest? Background Information Cell Respiration refers to the biochemical process conducted by the cells of an organism that combines glucose and oxygen to produce energy in the form of ATP, along with two by-products, water and carbon dioxide. The equation representing this chemical reaction is shown below. C6H12O6 + 6 O2 6 CO2 + 6 H2O + ATP Although plants and

For centuries, advertising has been a powerful way for companies to reach a wide audience of potential consumers and buyers. It has also been a good way to reflect the political, economic, and cultural environments of the community it is targeting. This is why many historians look at advertisements. Doing so allows them to gauge the attitudes and values of the time period and area in which the advertisements were produced and circulated. This idea of advertising and a society’s culture reflecting

During the biology lab, we did a various experiment to examine the hypothesis that there is a positive correlation between ancestral starch consumption and amylase gene copy numbers. These experiments were done to answer the research question: Is there an association between enzyme production, gene copy number, and gene evolution?!We did our experiments on the specific enzyme called Amylase which is responsible for hydrolyzing amylose to its monomers. At the very beginning of creating the calibration

powers’ with regards to their healing abilities. (Patching, 2008) In some areas of the world dog saliva would be used as an antibacterial because it contains some similar properties to that of disinfectants, which would theoretically be able to kill harmful bacteria in wounds and aid in the process of the healing. If a dog has an open wound, the dog is likely to lick the wound in order to ensure that their saliva has direct contact with the open sore to prevent growth of bacteria that could lead to infection

Effect of saliva contamination is a matter of great controversy. Few studies have reported that the use of dentine bonding agents under fissure sealants has reduced their sensitivity to saliva contamination and provided high bond strengths(85.86). Some have reported that the saliva contamination of dentine had no adverse effect on the bonding efficiency of one-bottle adhesive systems(10). Others have shown that the saliva contamination of the dentine surface produced a significant decrease in the

most prevalent method being Saliva Drug Test. Saliva provides a non-invasive and quick specimen for drug testing. A Saliva Drug Test ranges from detection of alcohol to cannabis, HIV antibodies to steroids. Saliva Drug Test enables a screening in a very short detection time period. They are designed to tell if someone has recently used a drug. There is no need for a specific place or a laboratory for conducting this test as it can be done with a small Saliva Drug

Prelab: Independent variable: pH levels Dependent variable: The effect of pH enzyme action Control: Positive: Saliva and HCL+ saliva Negative: Water Constant: Iodine solution (indicator) Hypothesis: At least two out of the three procedures will be indicated as starch, due to the fact that amylase is the first enzyme that breaks down carbohydrates Materials: • Paper • Pen/pencil • Saliva • Water • Hydrochloric acid • Pipette • Iodine solution • Construction paper • Timer Procedure: 1. A sheet

contemplated about it and concluded that the reason for the difference in taste had to be related to the amount of saliva present in my mouth. To investigate this conjecture, I did some research and found that my hypothesis was correct; the amount of saliva affected the breakdown

in the anticipation of another.” (Pavlov’s Dogs and Classical Conditioning, 2018) From the experiment, Pavlov proved the existence of an unconditional response from a “dog by presenting a dog with a bowl of food and measuring exactly how much saliva it produces”( Mcleod,2015) as shown in image 1. Pavlov, however, did discover that no matter what the object was or even what the dogs learned to associate with its food (e.g. lab assistant) would trigger the same response from the dog which led him

Introduction Sugar-free chewing gums are healthy alternative gums, it gives healthy effects on the salivary flow rate and acids (pH) in the mouth after a meal rather than gums that contain “unhealthy” sucrose. The sweetener that is used commonly to sugar-free chewing gum is Xylitol. It has been an essential healthy substitute that is also safe to use for children. 1In fact Xylitol has been approved by the Food and Drug Administration since the 1960’s (Shikhar Kumar, 2013) It can help to maintain

Draculin is an enzyme called desmoteplase (known as DSPA) found in the saliva of the vampire bat Desmodus rotundus. Vampire bats are found throughout the Central and South America, ranging from Mexico to the tip of Argentina. At night, these bats emerge from their roosts in hollow trees or caves, using echolocation for orientation, they detect the presence of prey with heat sensors located in the face. Vampire bats will usually land near their resting prey and then hop or crawl toward it. Once they

within the mouth and can be collected through saliva. Our experiment is to compare the difference between two processes which could potentially lower or increase the amount of each bacteria in the mouth. The question we are determining is, Does chewing 5 gum or sucking on an Ice Breaker mint producing more saliva to reduce the amount of streptococcus mutans and lactobacillus in your mouth? My hypothesis is that chewing 5 gum will produce more saliva therefore reduce

As of 2013, the number of people with MS was estimated to be over 2.3 million worldwide.( atlas 2013) Most of the non-traumatic disabilities in young adults are caused by MS [1]. It is considered that an interaction of genetic factors, environmental predisposition, and abnormal immune responses can be the chief causes of MS, But the exact etiology of MS is still in question [2]. MS has been greatly studied within the recent years, but a great number of clinical challenges still remain in regard
