AP Biology 11 February 2014 Observing and Analyzing the Rate of Cellular Respiration in Germinating and Non-germinating Black-eyed Peas I. Hypothesis If the cellular respiration rate of germinating black-eyed peas and non-germinating black-eyed peas is compared then the germinating black-eyed peas will have the higher respiration rate. II. Background Organisms need some sort of energy to facilitate their growth and development. Usually‚ this energy is in the form of adenosine triphosphate

THE EFFECT OF HYDROGEN BONDING ON RESISTING FLOW Design Investigating a factor affecting the viscosity of a mixture of liquid Research Question The effect of hydrogen bonding on resisting flow of five different liquids Background Theory Viscosity is the resistance of a fluid to flow‚ either within itself‚ or to moving past an objects moving through it. A liquid with high viscosity is thick and flows slowly. A liquid with a low viscosity is thin and flows quickly. Different liquids

Unit 5 P4‚ M1 and D1 This essay will explain the physiologies of the respiratory system and the cardiovascular system and how they work in the metabolism of energy in the body. The respiratory system The respiration system is the process of supplying oxygen to the cells so that cells can metabolise energy. The main functions of the respiratory system are to maintain oxygen supply to cells‚ to remove water from the body‚ and to remove carbon dioxide from the body. It is divided into four sections

HW Review for Photosynthesis exam: Due Monday March 28 Reminder your lab write up will be a next week. If your lab is this Friday you also will get a week to complete your full lab write-up. Sample questions: 1. twenty-five plants were placed in each of four closed containers and then exposed to light conditions shown in the data table below. All other environmental conditions were held constant for a period of 2 days. At the beginning of the investigation‚ the quantity of CO2 present in each closed

WORKSHEET MOLE By Sir Shah Murtaza Q1. Potassium reacts with water as shown in the equation. a. Describe what you would see when potassium reacts with water. b. A sample of 0.195 g of potassium was added to 500 cm3 of cold water. When the reaction was finished‚ 100 cm3 of 0.100mol/dm3 hydrochloric acid was added to form solution X. (i) Calculate the number of moles of hydroxide ions formed when the potassium was added to water. (ii) Calculate the

Unit 1: Introduction to Biochemistry Lesson 1-4: Key Question How many electrons does Mg2+ have? (1 mark) Mg2+ has 10 electrons. A magnesium atom has 12 electrons with 2 of the 12 being valence electrons. Therefore the atom will lose the valence electrons which are located on the outermost shell to stabilize itself (outermost shell) as atoms tend to do what it easiest. Since magnesium lost 2 electrons it becomes positive as it is giving away electrons to stabilize other atoms. Hence magnesium
