Abstract For this experiment we tested the effects of different adrenalin concentrations (0.001%; 0.01%; 0.1%) on the daphnia flea. The daphnia was placed on a slide with cover slip in order to examine its heartbeat by using the microscope. Aim In this Lab we will study the effect of different concentrations of adrenalin on the heart rate daphnia‚ the water flea. It is expected to recognize a threshold of the daphnia in its reaction the three different adrenalin concentrations‚ in terms of heart rate

BIOS 255 WEEK 5 Lab 5 - Lymphatic System & Disease Resistance 1. Describe lymphatic system functions. The primary functions of the lymphatic system are to drain and return interstitial fluid to the blood to absorb and return lipids from the digestive system to the blood‚ and to filter fluid of pathogens‚ damaged cells‚ cellular‚ and cancerous cells to help protect against invasion. 2. Locate each of the following lymphatic vessels: right lymphatic duct‚ thoracic (left

process. The data from experimentation provided sufficient results to suggest that the identity of unknown bacterium was the gram-positive spore forming bacteria‚ Bacillus Subtilis. Introduction. One of the main responsibilities of a medical lab is to determine the identity of pathogenic bacteria. It is important to determine the specific type of bacterium causing disease so the physician is able to correctly treat the patients. The structure of bacteria plays a crucial role of what antibiotics

Design Research question: This should be a clear focused question that says exactly what you are investigating. It shouldn’t be too long and it must include the dependent and independent variables. Eg. What is the effect of pH on the activity rate of salivary amylase? Dependent variable: activity rate Independent variable: pH Hypothesis: This is a paragraph or two where you explain your research question. You are going to say something like: "Salivary Amylase is a an enzyme that digests

Abstract The objective of this lab was to measure the amount of protein from a piece of beef liver . This was done by taking the liver‚ blending it and then using a centrifuge to separate the supernatant from the pellet. Once that was completed‚ ammonium sulfate was added to the supernatant‚ chilled and then spun for a second time. Next‚ 20 mL of water is added to the pellet‚ stirred and the volume was recorded. The teacher calculated the total mass of liver to be 10.098g. Lastly a spectronic

Lab #2: Energy in Cell Virtual Lab - Week 3 NAME: ________________________________________ 1. What is the importance of the light and dark reactions in photosynthesis? Photosynthesis works by absorbing light. Our sun gives off energy and the chlorophyll from the plant absorb this energy. The energy is then used to separate water into hydrogen and oxygen and then they combine hydrogen and carbon dioxide to make sugars. 2. What happens to food energy during photosynthesis? During
