Learn the basics about the atom economy principle of Green Chemistry, as a part of environmental chemistry. A reaction with a high atom economy is one where all of the atoms in the reactants are included in the final, desired product. Such a reaction would have little, if any, waste produced. A
Our body is a pretty fantastic feat of engineering. But how does it work? How do all of the different components come together to keep us alive, keep us functioning and achieving our goals? In this video we are going to look at the levels of organisation in organisms, from smaller than cells to bigg
Climate change affects biodiversity in multiple ways. Learn about it in our video! This video was created by Chris Ross. This video was created to support the campaign "Goal 13 - Climate Action". Find more information on our website http://simpleshow-foundation.org/. Click here to see more videos
We can use prime factorisation to find the highest common factors and lowest common multiples of any number - even large numbers. Before we jump straight in with discovering how, if you aren’t quite sure how to find prime factors, or want a factors and multiples recap - watch these videos first.
Triangles are the building blocks of all other straight-edged shapes. They were used for hundreds of years to create accurate maps and GPS today still works using trigonometry. Even the pixels on phones and screens use trigonometry.We need to know these things so that we can work out exact length
When a plant or animal species that once lived stops existing entirely, we say that that species has become extinct. Why do certain species of plants and animals sometimes become extinct? According to the theory of evolution, individuals of the same species show a range of variations. Some individ
Hepatitis B and C infections cause hepatocellular carcinoma (HCC) by replicating in hepatocytes. Inflammation, cell deathand proliferation result. Preventing infection from Hepatitis is important in decreasing the risk for liver cancer. This can be achieved through increasing hygiene standards and v
In nature, all organisms compete with each other for resources in order to survive. Competition between members of the same species is what makes organisms evolve. This theory of competition and ‘survival of the fittest’ is called Natural Selection, and was originally proposed by Charles Darwin i
On a circle, the tangent is always perpendicular to the radius. We use this key piece of information when finding the equation of the tangent. We then use our knowledge of the equation of a circle, and the equation of straight lines (y = mx + c) to find the equation of the tangent. Equation Of A Ci
Why does the Web love cats? And what’s Cat Content? You probaby have noticed that one animal is especially big on the Internet. Meow! Cats really took over the World Wide Web. But why are there so many cat videos, images, memes and gifs cluttering up the Social Web? What makes content-related to the
In this video we take a quick look at Gluten Sensitivity and how to treat it. Sources: https://www.glutenfreeliving.com/gluten-free/gluten-sensitivity/what-is-gluten-sensitivity/ http://www.healthline.com/health/allergies/gluten-allergy-symptoms#symptoms-of-wheatallergy1 This video was created by
In algebra, we replace a letter with numbers in the process known as substitution. Given the formula A = 1/2bh, if the base is 5cm and the height is 10cm, then the area is ½ X 5 X 10 because we have replaced the b with 5 and the h with 10. You just need to be be careful with negative numbers: it is
