speed up the activation rates that occur in living organisms. Without enzymes‚ it would be difficult to break down particles like food in the digestion system. Enzymes are all very specific to what chemical reactions they will work with‚ and the temperature‚ pH‚ and salt concentration have to be a specific levels in order for the enzyme to function. The structure of each enzyme has a fixed shape in which a certain the substrate will fit into. The sequence of the amino acids in the enzyme determines

experience some form of transition‚ and how well they deal with these changes as they are growing up will be depend on their stage of development‚ their confidence and the support and positive relationships they may have. The affects of transitions vary from child to child‚ so it is important to consider them on an individual basis. That said‚ it is possible to gain an idea of how a child’s social development may be influenced by a range of changes and the type of transition must firstly be considered

cylindrical projectile that can be boosted to a distinct height or distance by the combustion of its contents and is frequently utilised as a firework or signal. However‚ this term can also refer to a rocket engine. Similarly‚ to most engines‚ rockets burn fuel‚ which then turns into hot gas. The engine then pushes the gas out the rocket’s back‚ allowing the projectile to move forward. It is important to investigate how to successfully launch rockets to serve for different purposes. For an example

Discuss how different approaches to learning can affect student success in higher education Introduction: Approaches to learning are defined as “the ways in which students go about their academic tasks‚ thereby affecting the nature of the learning outcome” (Biggs‚ 1994 cited in Chin‚ 2000‚ p.110). However‚ the idea of classifying student’s approaches to learning began since Marton and Saljo’s research in 1979 (Ramsden‚ 2003). The research attempted to find an appropriate answer for the various

substance has a high enough temperature and pressure that both liquid and gas can exist at the same time. This state is called a critical point. Now‚ when a state of matter changes from one state to another is called a phase shift. Phase shifts are extremely important and most commonly observe phase shifts daily. For an example‚ when water freezes into ice‚ or the water in the shower turns to steam. To begin to start describing how a phase shift works we must understand factors that influence a phase

combined with baking soda. Then the temperature was taken‚ and finally calcium chloride was added‚ which formed a chemical reaction. Our lab question was how does the amount of calcium chloride affect the temperature of the product? We chose our independant variable to be the amount of calcium chloride added to the water/baking soda mixture. We had the dependant variable be the ending temperature. My hypothesis is IF we add more calcium chloride‚ THEN the temperature of the product will rise‚ BECAUSE

final conclusion can be drawn. The hypothesis was supported by graph 3 and 6 which both showed that an increase in concentration of the reacting species resulted in an increase in reaction rate. Both graphs have a positive gradient which clearly indicates that concentration increases the reaction rate. The hypothesis also proposed that as temperature increases the speed of the reaction would decrease‚ this is evidenced in graph 7 which shows a negative decrease in time as the temperature of the solution

From the results that have been gathered‚ it tells a variety of different things. Each temperature attempt was done three times to be accurate. First of all‚ the hypothesis (the higher the temperature the faster the reaction will occur) has been proven correct and it proves the theory right. From the results‚ we can see this‚ as the iced water (10 degrees) had the slowest rate of reaction at 1.10 minutes. Then the room temperature water (19 degrees) was tested and had a slightly better rate of reaction

How buyer behavior affects marketing activities in different buying situations Consumer buying behavior is ‘the mental and emotional processes and the observable behavior of consumers during searching purchasing and post consumption of a product and service’ (Batra & Kazmi‚ 2004). The exploration and capture information about customer buying behavior is extremely important to Sunshine. Consumer behavior involves study of how people buy‚ what they buy‚ when they buy and why they buy. It

These variables allowed for the experiment to be conducted accurately‚ with unexpected results. This is due to the enzymes being most active at 60ᵒC‚ it was that results were going to be most active at the 41ᵒC which is close to human body temperature. When we compare the enzyme in the low temperatures to the enzymes in the higher temperature we observed that the enzymes were
