John Snow, who was a practicing obstetrician in London during the Victorian era speculated that cholera, (originated from a contaminated water supply pump on Broad Street. Mayo Clinic (2017) has reported that “cholera is a bacterial disease usually spread through contaminated water. Cholera causes severe diarrhea and dehydration. Left untreated, cholera can be fatal in…
Introduction Hemophilia is a rare inherited genetic disorder that affects only one in every 10,000-40,000 people, depending on the type (Cimino, 2018). The disorder has two types, Hemophilia A, and Hemophilia B. Hemophilia A is a deficiency of growth factor VIII, and Hemophilia B is a deficiency of growth factor IX. Both growth factors are…
Whether you believe in a flat Earth, the heliocentric model or you think the Earth is a large, spherical dodecahedron with an all mighty solenoid dictating life itself, Neil Degrasse Tyson’s words will always apply to you. “To be scientifically literate is to empower yourself to know when someone else is full of bullshit” (Tyson,…
Research Question How does salinity affect the seed germination of Solanum lycopersicum? Introduction Relevance to Real world Covering 14% of Australia and home to over two million people, the Murray Darling Basin is Australia’s largest and most iconic river systems (figure 1) (McCormick, 2015). As over one third of Australia’s food supply is produced by…
DIGESTIVE SYSTEM The digestive system is a system where your food goes through. It begins with you eating your food, which goes through your mouth. Saliva contains something called enzyme which breaks down your food. The food then goes down the Oesophagus, a tube that runs from your mouth, all the way to your stomach.…
Introduction Rust is an iron oxide, a usually red oxide formed by the redox reaction of iron and oxygen in the presence of water or air moisture.[1] While rust in itself can be viewed as an inconvenience more than anything else, it can cause significant problems. It is known to encourage the growth of a…
Introduction: Basketball is an internationally known sport and is practiced by several different groups of people around several different areas in the world; in fact, it is one of the most popular sports in the world at the moment. To ensure a proper game of basketball, you need to have a good amount of elasticity…
Research question: How will increasing the voltage (v) to 5v, 10v, 20v, 35v, and then 50v affect the amount of current (Amps) measured by an ammeter, keeping the resistance (ohms) at 12 ohms and the wire length of 10cm constant, in a series circuit to prove ohms law? Background information on Ohm’s law: Ohms law…
Variables is a central idea in research, in simple, a variable is a concept that varies. A variable is something that can change, such as ‘gender’ and are typically the focus of a study. Variables are those simplified portions of the complex phenomena that a researcher intend to study. The word variable is derived from…
Instructions: For this investigative phenomenon, you will need to determine the percent yield of magnesium oxide from the given reaction to determine if it is a useful commercial process. Record your data and calculations in the lab report below. You will submit your completed report. Title: Percent Yield Lab Objective(s): The objective of this lab…
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,…
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…
