The Effects of Caffeine on Fish

Experiments are a scientific procedure which is used to test a hypothesis. There are two different types of experiments which are available to the researcher, these are laboratory and field.

Energy metabolism is where the nutrients oxygen and glucose are took in and delivered the organs. Energy is needed in order for our body to be able to function. Energy helps break down molecules and to build new molecules.

Metabolism is the sum of all chemical reactions that take place in the body and how fast the body utilizes the calories that we put into it. Body weight increases and decreases based on the amount of calories put in and the amount of energy we burn.

Metabolism is the word for every chemical reaction that takes place within a living organism. The energy is released from the food by respiration.

Experimental research concentrates on how and why something happens. It is the evaluation of how an independent variable (a manipulated factor) affects a dependent variable (an observed factor). The outcome can be affected by a number of elements; obtaining random and representative samples of the study population, experimenter bias and extraneous variables.

Metabolism is a chemical process that converts fuel from food into energy needed for the body’s activities. For example, thinking, running and jumping etc. are all an example of the bodies activities.

fuel, but cellular respiration is most often described as the oxidation of glucose, as follows:

Reflexes are the body's reaction something, reflexes are signals that are sent from your neurans to your brain and your brain processes the information then responds. To test if the difference between voluntary and involuntary effects the reaction time. In this lab the voluntary reaction time was the time between when the hammer hit the table and when the leg moved. The involuntary reaction time in this lab was the time between the time when the hammer hit the knee and the time where the leg moved.

Experiment- A research method in which an investigator manipulates one or more factors (independent variables) to observe the effect on some behavior or mental process (dependent variable). By random assignment of participants, the experimenter aims to control other relevant factors.

Introduction: Heart rate is the measure of beats the heart pumps per minute. A resting heart rate for a normal healthy individual is between 60-100. If the resting heart rate is above 100 it could be a result of Tachycardia and if it is below 60 it could be a result of Bradycardia. Heart rate can fluctuate due to over all health, whether you active or sedentary, or through certain substances we put in our bodies.

The objective of this investigation was to observe the affect of caffeine on the heart rate of a Daphnia (water flea), by observing the specimen under a microscope for a set period of time while in an environment of concentrated caffeine. By using a microscope, the collection of data regarding the heart rate of the how to make a line graph in word Daphnia was possible. Drinks such as coffee, Red bull, MONSTER and Coca-Cola contain high amounts of caffeine, causing the consumer to increase their amounts of stimulatory neurotransmitters (this is a chemical in the brain sent throughout the body telling your heart to beat, your lungs to breathe, and your stomach to digest). As caffeine is a stimulant, it is predicted that the drug will increase the Heart Rate of the Daphnia. Caffeine will be used in this experiment with concentrates of black coffee.

Introduction: Metabolism is a term in which defines all of the chemical reactions involving energy production. Some of these chemical reactions involve cellular respiration “by which is the series of metabolic process by which living cells produce energy through the oxidation of organic

“Metabolism is the set of chemical reactions that happen in living organisms to maintain life. These processes allow organisms to grow and reproduce, maintain their structures, and respond to their environments” (Metabolism). Metabolism breaks down the food that we eat, transforming it into energy for our bodies. Metabolism is broken down into two categories Anabolism and Catabolism, which help aid in the chemical reaction process. Specific proteins in the body control the chemical reactions of metabolism, and each chemical reaction is coordinated with other body functions (Dowshen). Metabolism is a constant process that begins when we're born and ends when we die. It is a vital process for all life not just humans, and

When a variable exerts influence on the dependent variable and isn’t an independent variable we refer to it as a(n): B. extraneous variable.

(ii) Experimental vs Non-experimental Research: Experimental research examine the possible influence that one factor or condition may have on another factor or condition. The experimental research is mostly conducted in laboratory, as it is in physics, biology and other pure sciences.
