Exercise 1 (20 marks) 1. What happens to the blood pressure and heart rate when the arterial resistance is increased? When arterial resistance is increased‚ the blood pressure increases and heart rate decreases. For instance‚ when arterial resistance increased to 150%‚ systolic blood pressure increases to 132.8mmHg‚ diastolic pressure increases to 82.1 mmHg‚ and heart rate decreased to 51.8/min. 2. What might give rise to condition with increased

There is a 25% chance that Allison and Tim will have a baby boy who is heterozygous for Tay-Sachs. b. No‚ the baby boy will not have Tay-Sachs he will be a carrier for the disease. The boy would only have the disease if he was homozygous recessive. | X | Y | X | XX | XY | X | XX | XY | 1:2 1:2 | T | t | T | TT | Tt | t | Tt | tt

Diffusion of Cell Size 2012 Kayla Szabo Loxton High School 2/20/2012 Rate of Diffusion Practical report Introduction: Diffusion is the movement of a substance from an area of high concentration to an area of low concentration. Cells need to utilise diffusion to exchange materials from outside of the cell to the inside of the cell for them to survive. Diffusion is a passive process‚ which means it doesn’t involve the need of energy. For a cell to survive it relies greatly on its size
