Rationale The nitrogen cycle (Figure 1.0.1) is complex and involves chemical, geological and biological processes. Flora, fauna and various bacteria are involved. Air is approximately 79% nitrogen but nitrogen gas cannot be used by most living organisms. Instead, plants must obtain their nitrogen from the soil as nitrate and animals obtain their nitrogen from plants or other animals. Nitrogen is...

The higher the temperature the faster the particles move. This is because of the kinetic energy, the more kinetic energy there is, the greater the chance is for a collision that results in a reaction. More energetic particles have a higher chance of “COLLIDING SUCCESSFULLY because they will collide more often thus increasing the number of successful collisions PER SECOND,...

The concept of alienation is represented in George Orwell’s novel, ‘1984’, and Stanley Kubrick’s film, ‘2001: A Space Odyssey’, as higher powers conceal the truth from the ordinary, lower class people. These two texts are interconnected by their depictions and perspectives of this reoccurring concept of alienation from fact, truth and reality. The Council and Mission Control (2001: A Space...

Throughout my school years, although I am quite young, I have noticed that most of my bilingual or multilingual acquaintances and myself show improved listening and the notice of fine details. They also had an impressive memory, which allowed them to learn another language easier than most students I encountered in Australia. Bilingual students who had to learn especially Japanese,...

I’m sure that at some stage in your life, most of you have probed for the answer to queries such as, is there life other than us in this universe of ours? If there is, is it aware? Advanced? Dangerous? A lot of people have wanted to know the answer to those questions, to see if ‘aliens’ exist. Some people...

Rationale In the practical experiment conducted different concentration levels of Tea Tree oil were used against the bacteria of Micrococcus Luteus to measure the effectiveness of Tea Tree oil at different concentrations. The experiment was originally the practical of “Which of the six natural antibiotics was most effective against the spread of Staphylococcus Epidermis and Micrococcus Luteus?” To the practical...

Introduction (200 words) Natural selection, a key concept in evolutionary biology, profoundly shapes the diversity of life. This principle, first elucidated by Charles Darwin, explains how species evolve and adapt through generations. It is the process by which traits that enhance survival and reproduction become more prevalent within a population, leading to the gradual evolution of species. This dynamic reflects...

Biotechnology; an area that has evolved drastically over time involves the use of biological systems to create a variety of products. This has enabled the ability to precisely manipulate genomes as seen in applications of artificial insemination, gene cloning, recombinant DNA technology to develop transgenic species etc. However, despite serving as a tool to increase the quality of life and...

Biotechnology can be defined as the exploitation of living systems and biological processes to develop tools for technological use. Applications may be used in areas such as industry (e.g. food, energy), medicine, environmental sciences, and computational design. The term ‘biotechnology’ was introduced in 1919 by a Hungarian scientist, Karl Ereky, to refer in general to processes where raw materials were...

Introduction The concept of Mars as the next most habitable planet has sparked an urge to investigate that has led to the discussion of sending a crew to Mars very shortly. As fantastical as it may seem, the idea has been thoroughly analysed to the extent where successful execution is possible but not without major setbacks and limitations. These risks...

Several billion years after a star’s birth its life will eventually end. How a star will die is determined by its mass, age, and type. The sun and other stars shine as results of reactions in its core. This changes light elements to become heavier and release energy in the process, which creates the necessary pressure needed to keep stars...

Judaism ethics pervade into the everyday lives of Jewish adherents. They stem from the legal system that has developed alongside Halachah, meaning ‘a going with God’ and prescribes how a Jewish person should behave. The basics of ethics originated from the decalogue given to Moses, determining that ethical life requires a spirit of mishpat (justice), tzedakah (righteousness), chesed (kindness) and...

RATIONALE Aquatic plants can be used to demonstrate the oxygen production in the process of photosynthesis because they are specialised to produce oxygen while submerged under water. The common aquatic plant that is used for most of the experiments is Elodea. In theory, when an aquatic plant is placed in a solution in the presence of appropriate light intensity, the...

Introduction Venus, ‘the morning/evening star’ is an extraordinary planet with many similar characteristics to Earth such that it is often called Earth’s twin. Located next to Earth, despite the similar mass and composition, the two planets are also very different. Examples of this include, Venus being the only planet in the solar system that spins clockwise rather than anti-clockwise, its...

At this stage, it is not possible for humans to terraform the Moon as the conditions on it are extreme. There are some basic considerations or needs for any long-term colonisation: breathable air, water, food, temperature, pressurised shelter and power, gravity, protection from radiation [2]. Breathable air The moon's atmosphere is so thin that there is no oxygen able to...

Introduction Production of curd by using Bacterial Probiotics Acidification of milk is one of the methods used in preservation of milk. Acidification, gives the milk a sour taste and it is achieved by bacterial fermentation or by the addition of an acid (for example: lemon juice or vinegar). The acid causes milk to coagulate and solidify fully or partially. Coagulation...

Enzyme is a protein molecule that takes on a particular shape which enables them to speed up biochemical reactions within the organisms, therefore behaving as a catalyst. It can also be used in industrial and medical contexts. Bread making, cheese making and beer brewing all depend on the activity on enzymes, and enzymes can be inhibited if their environment is...

Gene editing in agriculture Gene editing involves making distinct changes in the DNA sequence of a plant/animal cell creating a desired genetic make-up. Gene editing is a powerful tool for genome editing which requires high specificity and uses enzymes known as nucleases which cut the DNA at the desired site while another sequence is inserted to replace the cut sequence...

“Venus” went through cycles similar to that of the moon (from fully illuminated to crescent shaped). However, in saying this, I want to point out at this stage that although the phases of the moon and Venus are in fact similar, from my understanding, the reason that Venus looks bigger during crescent shaped cannot be applied to that of the...
