science is based on facts and theories and it reaches its results through an approved scientific method. Consequently‚ it seems to be objective and thus more truthful and reliable. However‚ other persons argue that this is a misunderstanding of science. Hence‚ one should question what science and knowledge entail. Can there actually be some form of knowledge that overrules all other types of human knowledge? Is scientific knowledge actually always objective? Are there other types of knowledge of equal

Rohit Dsouza Section A 122028 Problems with scientific research The article speaks of the trend in the scientific research‚ which is worrisome due to decline in the quality of research. Rising competition among scientists has led to a culture of “Publish or Perish”‚ which forces them to work on topics that are more appealing to people irrespective of their significance. They compromise on the quality of research by manipulating data or hiding unfavorable data. There are serious questions

Investigating the effect of changing substrate concentration on the activity of the enzyme catalase The aim of this experiment is to examine how the concentration of a substrate (hydrogen peroxide) affects the rate of reaction of an enzyme catalyse (found in liver cells) Research Question: how does changing the concentration of the substrate affect the rate of reaction of the enzyme catalyse? Hypothesis: As the concentration of the substrate increases‚ so does the rate of reaction until the reaction

The effect of time on enzyme reaction. Abstract: In this lab investigation we will observe how the amount of hydrogen peroxide is affected by catalase over time. The enzyme was added to 10 mL’s of hydrogen peroxide and observed over time to determine the relation between time and enzyme activity. The hypothesis stated that as time increased substrate would decrease. Therefore I predicted that at 60 seconds‚ there would be the least amount of H2O2. The enzyme activity mirrored my predictions

The purpose of the experiment was to find out how temperature affects the enzymes activity. For example‚ in Humans if the temperature is too high‚ the individual’s brain enzymes can denature and cause life threatening problems. The opposite can occur as well‚ if the temperature is too low‚ hypothermia can occur and it can be dangerous (Wilson‚ 1996). In the experiment optimal conditions for fungal and bacterial amylase was measured as well. Discovering information‚ such as the optimal temperature

Scientific Management Taylorism Frederick Winslow Taylor (1956-1915) observed in his role as a apprentice machinist that workers used different and mostly inneficient work methods. He also noticed that few machines ever worked at the speed of which they were capable. Also‚ the choice of methods of work were left at the discretion of the workers who wasted a large part of their efforts ussing inefficient and unstead rules-of-thumb. They kept they craft secrets to themselves (between the group

Biofuel Enzyme Kit Katie Adamson Biochemistry Laboratory‚ BIO124L 1/29/15 Abstract The objective in this lab was to determine the effects different conditions had on the enzyme cellobiase. We examined reaction rates in the presence or absence of an enzyme‚ the effects temperature and pH changes on the enzyme and the effects enzyme concentration and substrate concentration had on the enzyme. As expected results showed us that cellobiase works optimally when conditions are favorable. We see this

Scientific theories must have testable predictions. Predictions are made based on observations and then experiments can be done to test the theoretical predictions. The experiments will either verify or falsify the predictions made. Here we are going to discuss the hypotheses of phyletic gradualism and punctuated equilibrium. The pattern of evolution can be described as happening gradually‚ over time‚ as in the hypothesis of phyletic gradualism or by punctuated equilibrium. In the theory of
