Humans lose hair, sight, teeth, and muscles with age. Hearing is not any different. There are many reasons people lose their hearing ability as they age. Normal wear and tear are one of the reasons people’s hearing abilities decrease with age, damaging, breaking, and wearing out of hair cells. Sometimes the cells just die. The…
Introduction Ernest Rutherford was a New Zealand chemist and physicist. He is known as the father of nuclear physics because of his discovery of the nuclear structure of an atom. This is the discovery that will be explained in this report. This wasn’t his only discovery. He also discovered the concept of radioactive decay (half-lives),…
INTRODUCTION Yeasts are eukaryotic, single-celled microorganisms that belong to the fungal kingdom. When yeasts consume sugar and convert it to energy, they emit carbon dioxide, this is referred to as fermentation. The yeast will be more active and develop faster if there is more sugar present. While sugar and other sweets provide “food” for yeast,…
INTRODUCTION: Bath bombs consist of a wide range of ingredients, including bath salts, food coloring, fragrance, citric acid, sodium carbonate, and other components. Bath bombs ‘fizz’ when water inclines to trigger a reaction between an acid and a base (neutralizing substance). Many bath bombs contain citric acid, and sodium carbonate, which incline to have a…
ENZYMES AND METABOLISM Chemical reaction – a process that changes/transforms one set of chemicals into another. Chemical reactions always involve changes in the chemical bonds that join atoms in compounds. Reactants – elements that begin/enter the chemical reaction Products – elements that are produced by chemical reaction Energy may be either released or absorbed during…
HABITAT AND GEOGRAPHIC RANGE The Sea Nymph can be found all along the Australian coastline from the Exmouth Gulf in the north-west of Australia through to Victoria. The grass usually grows within a depth of 27 metres in the littoral and sublittoral zones (areas close to the shore affected by breaking waves and tidal currents)…
HABITAT AND GEOGRAPHIC RANGE Fur Seals are found all throughout the Southern Ocean around Australia and New Zealand, as well as parts of the Pacific and Indian Ocean coasts and islands in the subantarctic. They prefer rocky or boulder-strewn beaches, often on islands, that are somewhat secluded from humans. They occasionally venture to more vegetated…

Introduction Yeast is commonly known as a baking material for making bread and beer. However, under biological jargon it is a group of eukaryotic, single-celled microorganisms that makes up almost 1% of all fungal species.1 They are found in soils and on plant surfaces, like flower nectar and fruits, and they reproduce asexually through budding.…
Water is one of the most crucial sources for life on Earth, often causing problems when at lack. Local economic, environmental, and social conflicts are caused by water scarcity. Such conflicts derive from the economic benefits for the company, water privatization, by companies such as Nestle – Nestle Pure Life (bottled water). These big companies…
Abstract Proteins are very complex structures and have many variables that affect their function. This lab examined some of those variables. For the first part beef liver, which contains the enzyme catalase, was added to solutions of different concentrations of the substrate hydrogen peroxide. The second and third sections tested the effects of temperature and…
Introduction The Yangtze River, or “Child of the ocean” is the longest river in both China and Asia, as well as the third-longest river in the world. The river measures about 6,300 kilometers, with its glacial meltwaters extending from the Tanggula Mountains in Tibet to the East China Sea near the city of Shanghai, and…
Background information: Photosynthesis is the process in which plants go through to produce energy in the form of glucose required to survive. It is a chemical reaction that involves the use of carbon dioxide, water, and light. This process of photosynthesis takes place in the chloroplasts that are found in the leaves of the plant.…
Property Metals Nonmetals Metalloids Luster Metals reflects light from their surface and can be polished for example in gold, silver and copper. Nonmetals does not reflect light. They are not lustrous. Malleability Metals can withstand hammering and can be shaped into thin sheets such as foils. Nonmetals are non-malleable. Metalloids are not malleable. Ductility Metals…
Colour blindness is a condition which occurs when people are unable to see colours normally or not at all. There are many forms of colour blindness, the two most common being red-green colour blindness and blue-yellow colour blindness. A person with normal colour vision could probably see about 1-10 million distinct colours, whereas a colour-blind…
Anatomy: There are two main sections to the ear the central and the peripheral hearing parts. The peripheral hearing parts consist of the outer, middle, and inner ear. The outer ear contains the pinna/auricle, the eardrum, and the ear canal. The middle ear is a small space filled with air, that contains 3 tiny bones…
Introduction During a grip motion, the skeletal muscles in the arm and hand are used to generate and maintain the grip (Schoenfeld, 2012). Figure 1 shows the muscles, including the deltoids, triceps, biceps, and palmar muscles, that are involved in controlling movement and strength in the hand. Motor functions are controlled directly by the CNS…
INTRODUCTION The cell membrane surrounds the cell and is responsible for regulating substances within the cell. There are many processes in which substances can travel through the membrane, one being osmosis. Osmosis is a form of passive transport (no energy required) and is a type of diffusion in liquid substances. It is the transport of…
Introduction Palm Oil is a vegetable oil extracted from oil palm trees. Its scientific name is Elaeis guineensis Jacq. Palm Oil grows best in tropical climates with rich water. One of the main locations for Palm oil production is in Indonesia and Malaysia. There are two types of palm oil. One of them is Crude…
Rationale Photosynthesis represented by the equation 6H2O + 6CO2 → C6H12O6 + 6O2 is one of the most crucial chemical reactions on earth as it produces O2 molecules– a gas vital to the survival of many organisms (Vidyasagar, 2018) This process takes place during the light dependent phase of photosynthesis and is indicated by the…
