For a polynomial with real coefficients, use that roots come in complex conjugate pairs. Therefore, another root is 2-i (and we know for this example that the final root must be real). Write the factorise...

Mean for all students: (the sum of all the heights)/total number of students = (the sum of boys+sum of girls)/30 = 1.6sum of boys and girls = 1.6 x 30Mean for girls: (the sum of all the girls' heights)/to...

An action potential arrives at synaptic knob. This causes voltage-gated Ca2+ ion channels to open, resulting in an influx of Ca2+ ions diffusing into the synaptic knob. This then causes vesicles containin...

def fib(n):  if n <= 1:    return n  else:    return(fib(n-1) + fib(n-2))
This is the code for a very basic version. This coud be used to explain how recursion works thanks to a relatively easy ex...
