so the skeletal muscle cells are supplied with more oxygen and respiratory substrates used to generate energy in respiration where it is needed. A drug that increases heart rate is called a positive chronotrope‚ and this is demonstrated in this experiment when adrenaline is used to increase heart rate in Daphnia. One of the ways adrenaline increases heart rate is through the action of what is known as a ’second messenger ’ or ’transduction component ’‚ in this case it is a chemical made in the

Background Information The goal of this experiment is to measure the percentage of oxygen in air samples and this project will show an interesting way of doing that. The method depends on atmospheric pressure and a chemical reaction that removes oxygen from the air. I will find out what kind of chemical reaction can

Microbial Growth of Consumable Products By Bryce Wilmott AIM: To calculate the quantity of observable microbial colonies on the surface of the Agar solid‚ as to determine the presence of microbes in consumable products i.e. yoghurt and blue vein cheese. HYPOTHESIS: Microbial growth will be present in two of the three Agar plates (those containing the food product) due to the suspected presence of microbes‚ whilst the control Agar plate (containing no food products)

Lab 11: Mitosis Mitosis is a part of the cell cycle process by which chromosomes in a cell nucleus are separated into two identical sets of chromosomes‚ each in its own nucleus. Mitosis has several phases during the cell cycle. The experiment obligated pictures of onion root tips under the microscope. The pictures had cells and chromosomes. The pictures also had different phases of mitosis in them. As my hypothesis‚ cells stay in the interphase the longest. To begin the experiment‚ there were pictures

Experiment 7 General Safety Considerations 1. 1-Butanol and 1-bromobutane are toxic and irritating. Avoid all contact by constantly wearing goggles‚ gloves and working in the hood. Neither of these compounds can be poured down the drain. Like all products‚ 1-bromobutane should be turned in to your TA in a labeled vial. Any excess butanol should be discarded in non-halogenated waste. 2. H2SO4 is extremely corrosive. In very diluted form it can be poured down the drain‚ all other precautions

Abstract The aim of my research was to study automatic processes by replicating the previously carried out Stroop effect. The participants‚ 20 Richmond College students (10 boys and 10 girls) chosen by an opportunistic sample were taken into a quiet room separately‚ were presented with 6 lists of words‚ out of which 3 were congruent and the other 3 incongruent and the time taken for each participant to name the colour that the words were written in was measured and recorded. From

Trial # Guess Observation Explanation Trial 1 The dyed red water will not seep into the blue cold water. My guess was indeed correct and red water did not interfere with the blue water. Because the molecules in the blue water are much closer together because its cold and well the red water has warm/hot water and the molecules are everywhere. The molecules in the blue water are so dense that they’re making a layer so that the molecules from the red jar do not come through. Trial 2 I think
