A low level of glucose in the blood will stimulate secretion of glucagon to increase the amount of glucose in the blood. Glucagon causes the liver to release stores of glycogen to be converted to glucose...

As x is present as both numerator and denominator (top & bottom), we're going to use the quotient rule to solve this. The quotient rule is as follows:For y=f(x)/g(x), dy/dx=(f'(x).g(x)-f(x).g'(x)...

Differentiate the function to find the gradient at any point: df/dx = 2x - 1/(x+3)^2 - 4/(x^5)insert the value of 2 into f(x) and df/dx --> df/dx = 3.835, f(2) = 4.2625create the equation of the line b...

During the light dependent reaction, chlorophyll in the chloroplasts within a plant cell will absorb light energy, this will then excite electrons and an electron will be removed from the chlorophyll, onc...

Start by looking for multiples of 10. You have the pairs 2 & 5 and 1 & 10. Both signs are positive in the original equation so it will either be positive 2 & 5 or positive 1 & 10. Clearly ...
