Stem cells are human or plant cells which can turn into (differentiate) other cell types, more specialised for their job. They often help with growth of tissues and development of embryos. Human stem cell...

Firstly, multiply the whole equation by (4 - a) to cancel out the denominator, so the equation becomes: p(4 - a) = (3a + 5). Then expand the brackets: 4p - ap = 3a +5. Then rearrange the equation to: 4p -...

First start by considering the x⁰ coefficient which is -3. These include ±3 and ±1. Substituting x=1 into the polynomial produces an answer of 0 which shows that x=1 is a factor of the polynomi...

If the length is 5 times the width we can say that length=5a if width=a. We know the equation for: the area of a rectangle= length x width.In this case: area= 5a x a= 5a² and from the question ...

It is often hard to know where to start when analysing a poem. I think it is easiest to initially get a grasp on the content of the poem. This may seem obvious, but at first glance a poem can seem confusi...
