determine the electrical activity of the heart. As well as‚ to observe how exercise and different body positions(conditions) can affect the activity of the heart. Introduction Trained professionals can look at the EKG tracing and determine if the heart is normal or if the heart is abnormal. “An ECG records the electrical activity of the heart. The heart produces tiny electrical impulses which spread through the heart muscle to make the heart contract” (Kenny‚ 2015). There are two different types

The importance of good exercise helps the cardiovascular system work on sudden changes on demand if an individual exhibits good exercise skills that help the pulse rate increase and decrease when the body needs it (AHA‚ 1.) The purpose for this experiment is to give the student the opportunity to measure the lung capacity of a student

then their breathing and metabolic rate would slow down. My hypothesis is cold mealworms will have a slower metabolism. Materials and Methods For this experiment‚ you will need: 1. Two glass tubes with a diameter of 4mm and 20cm in length 2. Three live Mealworms 3. Wire rod 4. Cotton 5. Potassium hydroxide 6. Motor Oil 7. Petroleum jelly First‚ you will need to measure and record the weight of three mealworms to the nearest tenth. Then use the wire

OLD COINS TURN TO GOLD DESIGN: Problem or Research Question: How does zinc effects the color change in a copper penny? Hypothesis: If copper and zinc comes together‚ then it will form brass‚ which gives gold color to copper penny. Variables: There were no variables at this experiment PROCEDURES: Materials: Zinc (SN) filling‚ 3M NaOH solution‚ Copper penny‚ tongs‚ Hot plate‚ 100 ml beaker‚ 250 ml beaker‚ Bunsen burner‚ Water‚ Spoon. Procedure: First‚ we turned on the hot plate.

Investigation Investigate the amount of heat evolved when magnesium reacts with dilute acids. Planning What I am going to do I am going to find out how much heat is given out when magnesium reacts with a variety of dilute acids. In order to make comparisons between the acids‚ I shall use my results to work out how much heat would be given out if 1 mole of magnesium reacted with an excess of each acid. The acids I shall use are hydrochloric acid‚ sulphuric acid‚ nitric acid and ethanoic acid

genotype and phenotype are both characteristics of an organism. Genotype is the genetic make-up of an organism while phenotype is the observable characteristics of an organism. The expression of a trait‚ phenotype‚ can be affected by the Sullivan 2 genetic constitution‚ genotype‚ and other genes and environmental factors. Mendel found this out after doing an experiment with peas. He

excitation-contraction coupling mechanism between skeletal and cardiac muscles. Excitation-contraction coupling is the combination of the electrical and mechanical events in the muscle fibres and is related by the release of calcium from the sarcoplasmic reticulum. (Silverthorn‚ 2007) In the skeletal muscle‚ action potential in the nerves is generated when the somatic motor neurons releases the neurotransmitter acetylcholine (ACh)‚ at the neuromuscular junction. This initiates muscle action potential which is then
