Just weeks ago on September 28th, Japan’s governmental health and science ministries officially drafted national guidelines on human gene-editing and manipulation experiments, particularly within embryos (Cyranoski, 2018). Before then, Japan’s stance on genetic experiments had remained neutral. Now it is joining an increasing list of countries who support this genetic innovation. One of the…
Stearic acid is known as Octadecanoic acid, one of the common long-chain fatty acids being a very useful saturated fatty acid present as a combined form and a major component in products such as cocoa and shea butter, and various plant and animal fats. Having 18-carbon as its backbone, the chemical formula of stearic acid…
In mathematics we utilise quadratics and it can represent real life situations such as describing shapes, to show how a product is increasing or decreasing in sales. It has a U shaped curve known as a parabola, it can vary in the being of the parabola are proportional to changes in the square of that…
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…
An earthquake is caused due to the movement beneath the earth’s surface. It is caused by the vibration of rocks and the sudden release of energy in the earth’s interior. When two tectonic plates slip past each other and pressure starts to build up at the edges, vibrations called seismic waves are created. The extent…
Table 1. Solution concentrations, volumes and observations for Experiment 1: Observing the enzyme reaction. Test Tube dH20 Potato Extract Catechol Observations 1 5 ml + 500μl —– 500μL Solution turned milky-white to clear. (High substrate) 2 5 ml 500μl 500μl Solution turned yellowish-brown. (High substrate) 3 5 ml + 500μl 500μl —– Solution is clear,…
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…
Through which city does the prime meridian run? Greenwich, England What are the dates of the solstices and equinoxes? Summer solstice: June 21 Winter solstice: December 22 Vernal equinox: March 21 Autumnal equinox: September 22 Describe Earth–Sun relationships in terms of orbit, the Sun’s position, tilt and direction of Earth’s axis as it…
Of what two gases was Earth’s first atmosphere primarily composed? diatomic nitrogen, carbon dioxide What are the percentages of Earth’s three most abundant constant (non-variable) gases in the atmosphere? nitrogen (78.08%), diatomic oxygen (20.95%), argon (0.93%) What are the variable gas within Earth’s atmosphere? water vapor, carbon dioxide, methane, hydrogen, nitrous oxide,…
Chapter One Outline Settling the Continent Who are the Indian People? Native people living in the “New World” at the time of its discovery by Europeans. No single physical type characterized all native people. There were over two thousand tribes/groups that all had varying cultures/languages. Once the “New World” was discovered writers proposed theories…
Water has many unique characteristics which make life possible on earth and support it. One of these properties is water’s high specific heat, or water’s ability to resist changing temperatures. In terms of water’s chemical nature this is possible because of the large amount of energy which would be needed to break the hydrogen bonds…
During the late 1890s the creation of the quantum mechanics and Einstein’s Relativity beckoned a new age in physics: modern physics. The terminology of modern physics refers to any branch of physics, such as nuclear physics or electromagnetism, which was developed in the early twentieth century or older branches that were greatly influenced by twentieth…
The use of electricity is a relatively new discovery when considering the history of mankind. Its use became particularly popular in the experiments conducted by Thomas Edison when he created the first electric light bulb. The light bulb featured the use of a direct current which moved the electrons in one continuous direction. The use…
The extinction of species has been an ongoing cycle since life first formed on Earth. Some species have died out through natural selection, meaning they were unable to adapt quickly enough to the changing environment. Others have been plucked from existence by humanity’s work, whether it be by over-hunting, habitat destruction, or other means. Whatever…
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…
Introduction: This experiment explored how aerobic respiration from exercise affects a basic solution and its transition to an acid. More energy is used during exercise, more oxygen is required in the human body to fuel cellular respiration. Cellular respiration produces energy in the form of ATP and releases CO2 is a byproduct. It’s equation is…
Introduction: The purpose of the lab was to find which metal is the most reactive and which metal is the least reactive. It was known before the experiment that the metals used in the experiment are placed in the activity series from most active to least active as follows: magnesium, aluminum, zinc, and copper. The…
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…
Introduction This lab will answer whether or not initial speed affects the time that a projectile is in the air. Also, it will be determined if there is a direct relationship or not between initial speed and time. Experimental Procedure Set the values to the following: Angle – Zero degrees Initial Speed – 10m/s Mass…
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…
