SCIE211 Phase 2 Lab Report Title: Speciation Instructions: You will need to write a 1-page lab report using the scientific method to answer the following question: • What would happen if a species within a population were suddenly split into 2 groups by an earthquake that creates a physical barrier like a canyon? When your lab report is complete‚ post it in Submitted Assignment files. Part I: Use the animated time progression of speciation to help you write up your lab report. Part II: Write

application of shear stress. However‚ fluid can apply force normal to any surface contacting it. If the fluid is considered as a solid object such as a cylinder‚ the pressure acting on a surface is the same as the pressure on the opposite side of the object‚ but in a different direction. This condition can be applied to any surface on the imaginary fluid shape. This thus defines that the pressure on a fluid is isotropic‚ meaning that the force/pressure in any direction applied on the liquid is the

Human ECG Abstract The purpose of these lab exercises is to understand the function and importance of an electrocardiogram. This lab will demonstrate how stress levels or different elevations can affect human heart rate. Furthermore‚ the equipment used in the experiment will show the functions in the right and left arm; as well as‚ in the right and left ankles. Finally‚ the lab will serve a purpose as a way to know how to read an electrocardiogram and calculate the heart rate. Introduction

Wood types differ considerably in properties such as color‚ density‚ and hardness‚ making timber a resource that is valuable in a wide variety of contexts. Each of the samples of commonly used woods shown here has distinctive characteristics. Mahogany is a tropical tree prized for its heavy‚ strong‚ easily worked wood. Hickory is a tough‚ hard wood used for tool handles‚ furniture‚ and smoke wood for meat. Instrument makers favor the strong‚ richly colored wood of the cherry tree. Yew is strong‚

which means that they have a cavity in the joints that contains synovial fluid. Joints are not just made of bone‚ because if they were‚ friction would keep them from moving smoothly. The body uses cartilage and the synovial fluid to reduce friction in joints. Osteoarthritis happens when cartilage wears away over time and exposes bone to bone and increases friction‚ which is very painful. Synovial fluid is a fluid-like material that is present in many of the joints of the body. It serves the purpose

gas exchange and thus physical activities. Exercise over time increases one’s physical fitness. A way to measure fitness is by taking a blood pressure reading. Blood pressure is read by a device called a sphygmomanometer. Blood pressure is the force of blood moving along the elastic walls of arteries. The top number is the systolic reading‚ corresponding to the contraction phase of the heartbeat. The bottom number is the diastolic reading and corresponds to the relaxation phase of the heartbeat

Into the woods Into the woods is like a fractured fairytale. It has little red riding hood‚ Cinderella‚ jack and the bean stalk‚ and the baker. Little red riding hood stops at the baker’s house for some sweets for her grandma who is sick in bed. Then the witch from next door to the baker comes over and says that there was a spell on his family and the spell was that he couldn’t have any kids. The baker and his wife really wanted a kid. So the witch told them that they would have to get certain

AP Bio Block B Photosynthesis Lab 12/6/12 Introduction: Photosynthesis is affected by light intensity‚ water‚ and temperature. Plants grow more abundantly because the weather is warm. Carbon Dioxide given off by animals is consumed by plants that replace the oxygen animals take it. Experimentation will help understanding how plants are vital because of the oxygen they release. If leaf disks in the experiment release oxygen‚ they will undergo photosynthesis and float. If
