An Increase in Light Intensity Increases the Rate of Respiration M. Chauntise‚ S. Shaika‚ R. Shantal INTRODUCTION The sun plays a vital role in sustaining an entire living world whether indirectly or directy using a transformation process called photosynthesis. This process assists in nourishing plants and keeping them alive. For example‚ trees grow very tall in the rainforest where there is an abundance of water in order to reach as much light as they can. For this reason‚ in order to survive the

The effect on rate of an enzyme catalysed reaction by different objectives which include effect of substrate‚ temperature‚ ph and effect of a competitive inhibitor phosphate ions. This is determined by the reaction of hydrolysis by p-nitrophenylphosphate (PNP) as a substrate by the enzyme phosphatase. Abstract The hydrolysis of p-nitrophenyl phosphate has been studied in human red blood cells. To see if hydrolysis was related to the functioning of the sodium pump. Acid phosphatase catalysis’s

The affect of psychological stress on the heart rate. Introduction: The human body is incredible machinery that can adjust to stressful situations and react in a “fight-or flight” manner by temporarily shutting off nonessential‚ at the moment‚ immune and digestive systems. When the body is ready for a challenge‚ heart rate increases‚ blood pressure rises and glucose production intensifies to supply large amounts of energy. These metabolic changes are caused by release of stress hormones (catecholamine

Oil Spills and Its Effects on Marine Life Many people do not realize the impact of the oil spills that occur in the ocean. It is like putting water into a heated oil frying substance. It is quite catastrophic. With all the oil spills that have already occurred it is important to help clean ‚and prevent oil spills from reoccuring. There is indeed a lot of reasons as to why we should clean and help prevent oil spills from happening but here are the three main reasons. First reason being oil spills

Leadership Reference Groups – use other people as a frame of reference. Primary groups are intimate‚ face-to-face such as family and peer groups. Informal primary groups include family and peer groups. Formal groups are highly defined in structure‚ interact frequently‚ such a school groups‚ business groups and work groups. Primary groups are more important to you. Secondary groups are seen less frequently. Informal groups are considered secondary and more impersonal as they only interact

increased chance of collisions between reactant particles. Since the collisions become more frequent and abundant‚ the rate of reaction increases. Aim The aim of the experiment is to see if a greater surface area of a dissolvable tablet creates a faster or slower reaction Independent Variable The surface area of the tablet (halves‚ powdered and whole) Dependent Variable How fast the rate of reaction is to the surface area Controlled Variables The amount of water (250mL) The type of dissolvable

Chemistry IA How does the molecular mass of alcohols affect its rate of evaporation? Introduction Alcohols are some of the most important molecules in organic chemistry. They can be converted into many different types of compounds. Alcohols contain the hydroxyl functional group (-OH)‚ bonded to a carbon atom of an alkyl or substituted alkyl group. The weight of the different compounds will differs because of the amount of hydrogen bonding. There are three kind of alcohols‚ primary‚ secondary
