With regards to the non-specific immune response, phagocytes engulf and digest pathogens through phagocytosis. Natural killer cells detect infected cells through monitoring the presence of particular sign...

15x^2 − 4x + x^2 + 9x − x − 6x^2 = ?First you can break up the question and sort out the x^2 part of the equation to make it easier: 15x^2 + x^2 − 6x^2 = 10x^2Then you are left with solving the second p...

Use the FOIL method:F - FIRST: the first term in either bracket, multiply: 2x(9x) = 18x². O - OUTSIDE: the terms further from the centre of the brackets, multiply: 2x(-2) = -4x. I - INSIDE: the...

Range is biggest possible difference, so we need to find the largest weight and the smallest weight given to us:
Heaviest = 74.2kg (Jim) Lightest = 67.8kg (Connie)

To find the differen...
