When T cells bind to viral antigens presented by macrophages they undergo mitosis to form 4 distinct cell variants: Memory T cells- remain in the blood stream to initiate a faster immune response upon re-exp...

Water has strong intermolecular hydrogen bonds that hold the water molecules close together, making it very dense. As water freezes, the hydrogen bonds move further apart as it forms a hexagonal lattice. Thi...

The general equation of a circle takes the form (x - A)^2 + (y - B)^2 = r^2 where (A,B) is the centre of the circle with radius r. Thus, we aim to rearrange the equation in the question to match this form. S...

Use the cosine trig identity, cos(a-b)=cos(a)cos(b)+sin(a)sin(b) ,to write Rcos(x-a) as R(cos(x)cos(a)+sin(x)sin(a)).Now we can equate the coefficients of the sines and cosins on either side of the equation ...
