Experiment to investigate the effect of concentration of electrolyte on the current of voltaic cell Aim The aim is to identify the relationship between the concentration of H2SO4 solution and the current of Cu-Zn voltaic cell. Hypothesis My hypothesis is that the greater the concentration of sulfuric acid the bigger the current of the voltaic cell. In a voltaic cell‚ chemical energy is concerted to electrical though the oxidation and reduction happen on the electrodes. Current will not flow

“Tuskegee Study of Untreated Syphilis in the Negro Male” began. The original intent was to learn the effects of syphilis on the body. The study began with 600 black men and was intended to last six months. Shamefully‚ the ethics of this experiment were nonexistent as misinformation and deception led the experiment to last a striking forty years. A primary object for the disgust surrounding the experiment was the lack of consent. Currently‚ the Institutional Review Board (IRB) requires informed

Heart Rate Experiment Introduction: The heart rate measures the contractions of your heart and is a requirement for life. The heart uses four chambers. The right and left-lower chambers are called ventricles‚ and right and left-upper chambers are called atria. These four chambers complete two cycles that replenish the tissues with oxygen and get oxygen from our lungs. The heart rate is measured in beats/ minute and a “beat” is when the lower chambers are (two ventricles) contract. This

Induced Fit Model (Hudon-Miller‚ Enzymes‚ 2013) Why Does Aldolase B Deficiency Lead to HFI? • Understanding what happens to Glucose and Fructose in the liver is the first step. • Glucose enters the liver cell and Glucokinase is in the cytoplasm and adds a Phosphate (Pi) to make G-6-P to keep the glucose in the liver cell‚ which then becomes G-1-P and can be

Metabolic Disease Luise Crinklaw Carrington College What is metabolic disease? Metabolic Disease or syndrome can strike anytime in a person’s lifetime from the very young to the very old and it has even been reported to affect animals. The disease itself takes on many forms and doesn’t affect each person the same way. Treatments vary according to each individual’s symptoms. Now let’s go into what exactly are metabolic disorders

INTRUDUCTION Experiments with animals In this project we chose to write about experiments on animals because we are owner of pets at home and this topic is pest us!: this animals have life too ‚ this animals are like humans they are a part of our family-they have feelings/thoughts/rights like a humans and the experiments are cruel and it make them to suffer!!! There exaggeration trials assessing the necessity of understanding the extent of suffering and a lot of experimental animals When we

abnormalities and diseases‚ many of these animals are unable to live on. As for animals’ daily living conditions‚ they spend their lives in cages‚ not being able to live freely with choices or communicate. They never get to experience the outdoors of fresh air and sunshine‚ instead‚ they are contained within bars and walls. Not only that‚ their cages are small and crowded‚ and they live with loud noises and bright lights that are known to cause stress in animals. Days after days in laboratories‚ they

detail Do you agree with the use of the animals in experiments? Why or why not? Fully explain your response. Points to consider in your response: The purpose of the study The type of study (observational‚ medical‚ etc) The type of animals being used The use of animals in experiments can be extremely helpful in understanding humans. Animals have similar physiology‚ genetics‚ similar learning and emotional processes as humans. I believe animal experiments are necessary in order to advance medical

Metabolism By: Who ever Enzymes Enzymes act as a catalyst by speeding up or slowing down processes in the body. A protein enzyme has a particular shape that contains an active site. An active site is where a substrate fits into place to have its bonds either built or broken. At which time the products or product produced are released. The enzyme remains to continue to act on any available substrate. Hereditary Fructose Intolerance AldolaseB is found mainly in the liver. The second

Metabolism is the complete and necessary chemical activity carried out by living organisms. This process is carried out in two different ways: anabolic and catabolic. The catabolic breaks down large chemical compounds while anabolic synthesizes components to create larger molecules. Respiration provides energy for these reactions‚ and respiration needs oxygen to occur. Thus‚ calculating the change in oxygen can determine metabolic rate (University‚ 59). In this experiment‚ we will observe and analyze
