Exam stress happens to everyone. Once you turn the exam paper and see the question, you can't help but panic. Your thoughts begin unfolding rapidly, you make a simple mind map, and in a few minutes time you ...

They squeeze through the walls of blood capillaries, moving through tissues to reach the site of infection. Phagocytes ingest pathogens by endocytosis (phagocytosis), a non-specific immunity, which doesn't d...

Arteries carry bloock away from the heart, towards bodyily tissues. They have thick walls to withstand high pressures, a narrow lumen to maintain high pressures and a thick layer of elastic fibres to maintai...

First expand out the brackets: 5x-15 = 4y -3xy Then re-arrange to bring all the x terms to one side: 5x+3xy = 4y +15 Now factorise: x(5+3y) = 4y + 15 Now we have isolated the x term, we can divide both sides...

we have dy/dx = -x/y , so we treat the differentials as fractions and write y dy = -x dx. Now integrating the left side with respect to y and the right side with respect to x, we have y 2 /2 = -x 2 /2 + C. W...
