Lab Report Explained: Length and Electrical Resistance of a Wire

 INTRODUCTION AND BACKGROUND THEORY When electrons travel through wires or other external circuits, they travel in a zigzag pattern that results in a collision between the electrons and the ions in the conductor, and this is known as resistance. The resistance of a wire causes difficulty for the flow of the electrical current of a…

Earth Sciences Study Guide: Atmospheres

From Figure 4.2, describe the geographic locations where coastal upwelling is important (e.g., “west central and southwestern South America”). Upwelling causes some of the coldest surface temperatures on Earth. The low surface temperatures stabilize the overlying atmosphere, causing cool dry climates (deserts) to dominate the western edge of South America. Upwelling is important where coastlines…

Essay: Are Genetic Privacy Laws Necessary?

Genetic Privacy laws exists to prevent the abuse of genetic information. It is understood that these laws were created specifically to prohibit health insurance companies, employers and housing agencies from using genetic data to discriminate against citizens.  Genetic discrimination can be described as the unfair treatment of individuals by employers/insurance companies based on gene mutations…

Lab Answers: Uniformly Accelerated Motion (Incline)

Introduction This study focused on an object in motion with a uniform acceleration.  Using the Motion Encoder System and LoggerPro, the position, velocity, and time were taken and analyzed with the goal to determine linear and quadratic acceleration.  Interpreting the graphs allowed discovery of the affect of acceleration due to Earth’s gravity.  This was represented…

Lab Report: The impacts of salinity on modern agriculture

1.0 Background: A breakthrough scientific experiment conducted by ‘Carnegie Science’ found that soil salinity considerably affects the growth rate in plants.  The experiment found how plants create Abscisic Acid as a stress hormone when the endodermis is exposed to drought or saline environments. “The endodermis also acts as a guard, with Abscisic Acid, to prevent…

Vitro meat, Hydroponics and Xerophytic adaptations

As the population grows at an exponential rate, feeding the world’s people is becoming an increasingly important field of scientific concern. Projections predict that population will grow more than 2 billion by 2050. This rapid growth cannot be sustained in definitely and will be either at the expense of a lower lifestyle quality or dramatically…

What is Cloning? Risks and Benefits

Cloning, a reproductive process resulting in two or more identical copies of organisms is a relatively new field of inquiry, making genetically identical organisms artificially.  Within the world of science there are two categories of cloning, natural cloning such as identical twins and artificial cloning which is a clone produced by artificial means.  There are…
