The best way to prepare for an English exam is (having read the texts) to explore the themes within the text, as these are likely to form the basis of the exam questions and it will also give you a more t...

Sarcomeres are formed of myosin and actin filaments which are interleaved. If myosin cannot bind to each other then thick filaments cannot be formed. Thus, there is nothing to anchor myosin so actin canno...

15: (x+y+z)/3 = 6 so, x+y+z = 18.Range = highest number - lowest number. For the max range, at least 1 of the numbers must be 1. 1,1,16. 16-1 = 15

Quadractics factorise into double brackets like (x-a)(x-b). We ave to find the facors of -21 which add to make +4. 7 and -3 suffice. (x-3)(x+7) Then x will be equal to 3 and -7 for the equation.

Step 1: Start off by labeling the 2 equations. 3 x + y = 7 will be equation 1. 3 x - y = 5 will be equation 2.

Step 2: rearrange equation 1 to make y the subject. 3 x + y = 7 ---> y = 7 - 3 x (h...
