Transcription is the process which makes mRNA in the nucleus. Firstly, the gene uncoils and hydrogen bonds are broken, causing the two strands to separate. One of these strands is the template. RNA nucleo...

A synapse is gap between two neurones. When a nerve impulses travels along the axon reaches the end of the pre-synaptic neurone, the release of chemical messengers (called neurotransmitters) is triggered....

4 sin(x) – 8 cos(x)= Rsin(x-a) here use double angle formula

4 sin(x) – 8 cos(x)= Rsin(x)cos(a)-Rcos(x)sin(a) Rearrange so in same format as LHS

4 sin(x) – 8 cos(x)= Rcos(a)sin(x)-Rsin(a)cos...

First identify your x1, y1 and x2,y2. It is helpful to write this above the two points A and B. To find the gradient the following equation can be used (I will show equation on board),as u can see the X1,...
