Respiration is the chemical process that supplies the body with energy for all other life processes: growth and repair of cells, muscle contraction, protein synthesis, sending nerve impulses, absorbing molecules in active transport to name just a few. It happens in ALL living cells, not just anima
We explain how to recognize and treat a heat stroke. We also look into the risk groups and how to prevent it from happening. Summer is the time of heatwaves and a heat stroke is a serious medical emergency. Always remember to drink a lot of fluids! Click here to see more videos: https://alugha.com/
In this video we are going to look at how to find the equation of a straight line that passes through two given points (coordinates). You should already know that a straight line follows the y=mx+c format, where 'm' is the gradient and 'c' is the y-intercept. Start by finding the gradient either usi
In this video we look at the basics of algebra, focusing on the notation that is used. In algebra we use symbols to represent numbers. These symbols are called variables. Some reasons for using symbols instead of numbers is that the symbols, or variables, can represent unknown quantities and for s

SOHCAHTOA, Pythagoras, sine rule and cosine rule and all things trigonometry actually have a lot of uses in “real life”. Such as working out distances to things, heights of buildings and mountains, navigation at sea. An important part of “useful” trigonometry are angles of elevation and depression.
The study of finches led to the development of one of the most important scientific theories of all time. In December 1831 a naturalist called Charles Darwin boarded the HMS Beagle, bound on a surveying voyage of South America. Whilst the ship and crew carried out coastline surveys, Darwin was fre

Woman between the ages of 12 and 50 years old undergo a monthly cycle in which their uterus prepares for pregnancy; it prepares for a fertilised egg to settle and grow into a baby. If pregnancy does not occur, the lining breaks down and is expelled from the uterus. This is known as menstruation.
In this video we are going to look at rearranging straight line equations to find the gradient and y-intercept. Straight lines follow the equation y=mx+c, where the m is the gradient and the c is the y-intercept. But straight line equations aren’t always written out in this nice form. Sometimes we h
In this video we are going to look at how we work out whether a number is in sequence or not. We looked at finding the nth term rule, generating sequences from it and finding terms in a sequence from the nth term rule in part 1. Is 730 a term in the sequence 3n + 11? 730 isn’t the term, so we cannot
