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 of milk inhibit the growth of harmful bacteria and improves the dairy product's shelf life. Soured milk that is produced...

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 too acidic or too basic. The rate of action of an enzyme is highly dependent on many key variables, including...

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 (Fridovich-Keil, 2019). The development of gene editing techniques was challenging; however, the breakthrough of gene editing was made successful by...

“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 moon. Why? Well although it seems rather intuitive that we may be able to apply the same principles as did...

INTRODUCTION Everyone needs sun exposure as when the skin is exposed to the sun, our bodies make vitamin D (Kate M. Cronan, 2019). This helps the body to absorb calcium for stronger, healthier bones (Kate M. Cronan, 2019). “Too much unprotected exposure to the sun’s ultraviolet (UV) rays can cause skin damage, eye damage, immune system suppression, and skin cancer. Even people in their twenties can develop skin cancer.” (Kate M. Cronan, 2019). “More than 11,500 Australian men and women...

Venus’ surface is uninhabitable by humans for many reasons. Not only does Venus’ atmosphere contribute to the huge amounts of air pressure, over 90 times that of Earth’s, but the dense, mostly carbon dioxide atmosphere traps a ton of heat. This sends temperatures skyrocketing to around 467 °C, hot enough to melt lead [1]. Together, these factors crushed many probes sent to Venus, including the USSR’s Venera 3, which didn’t even survive long enough to send over a byte of...

The whole universe is expanding in all directions; however, everything was closer together 13.8 billion years ago and at one point all the galaxies converged to a single point (Howell, E. 2017). It is said that the universe has expanded to get as large as it is now, and that it will continue to expand. When the universe started as one point, it was just hot, light and energy combined with miniature particles. Nothing like what we see now as...

INTRODUCTON A redox reaction is a type of chemical reaction “that involves a transfer of electrons between two species” (Spohrer, Breitenbuecher & Brar, 2019). For a reaction to be classified as redox, there must be one species that is reduced and another that is oxidised. This means that both reduction (the gain of electrons) and oxidation (the loss of electrons) occur simultaneously in a redox reaction. One such example of a redox reaction is that of electrolysis. Electrolysis defined broadly...

Genetic modification is the process of altering the genetic makeup of an organism. This has been done indirectly for thousands of years by controlled, or selective, breeding of plants and animals. Modern biotechnology has made it easier and faster to target a specific gene for a more-precise alteration of the organism through genetic engineering. The terms 'modified' and 'engineered' are often used interchangeably in the context of labeling genetically modified, or 'GMO,' foods. In the field of biotechnology, GMO stands...

Introduction In our modern society, a plethora of chemical processes and reactions are commonly found in our everyday environment and are significant parts of the products we use. One such process is a redox equation, which consists of oxidation and reduction. Originally, oxidation and reduction were viewed in terms of adding or removing oxygen. Now, they are defined in three different ways; the loss or gain of oxygen, the loss or gain of hydrogen, and the loss or gain of...

WHAT IS GENETIC MODIFICATION A transgenic species (TGS) is defined as an organism that has had part of another species genome transferred into its own gene through the techniques of genetic engineering. This is often called “Genetic Engineering”. It allows selected individual genes to be carried from one organism into another and their traits to be passed on. Further, transgenic is the process of extracting deoxyribonucleic acid (DNA) from another organism’s genome and combining it with the DNA of the...

In a bid to aid globalisation, the Australian Government established liberal trade policy agreements with low wage economies. However, according to a manufacturing report released in 2018 by the Department of Industry, Innovation and Science, it suggests liberal trade policies are hampering the growth of Australia's manufacturing industry instead of fueling economic growth. Australia’s manufacturing industry contributes 6% to the Australian GDP, however the utilisation of manufacturing has declined considerably over recent years. The Australian manufacturing industry exports $96.1 billion...

Introduction Electrolysis is when an electric current pass through a chemical solution to create a non-spontaneous chemical reaction (Britannica, 1998). Electrolysis can be used to separate compounds into its original elements (libretexts, 2019). In electrolysis, the reduction - or the gain of electrons - and the oxidation - or the loss of electrons occurs. This is referred to as Redox reactions. When a battery’s positive and negative terminals is connected to the electrodes it can alter the charge of the...

Influenced by anthropogenic climate change, the complex nature of the human-animal interface is continuously threatened and zoonotic diseases are rising. Domestic animals themselves are reservoirs of zoonotic diseases (e.g. Avian influenza) and poor livestock practices endangers both humans and animals. Encroachment of human settlements increase the interactions between humans and wildlife species which helps facilitate the spread of zoonotic diseases. Atmospheric carbon dioxide in the environment also influences the animal-plant interface with invasive species dynamics fluctuating (Naicker 2019). A One...
