G&T 6 Mark questions
1. Explain how the small intestine is adapted to carry out efficient exchange?
2. Explain how are the lungs adapted to carry out efficient gas exchange?
3. Plants lose water by a process called transpiration. Explain what factors may lead to increased transpiration and describe how plants have evolved to overcome this problem.
4. The heart is said to have a ‘double circulation’, explain what this term means, the evidence for it and the function.
5. The blood is made up of four main components: plasma, platelets, red blood cells and white blood cells. Explain the function of each component.
6. Evaluate the use of kidney dialysis and kidney transplants to treat renal failure.
7. Describe how a healthy kidney produces urine.
8. Describe the changes that take place in the body when the core body temperature becomes too high.
9. Describe the changes that take place in the body when the core body temperature becomes too low.
10.Explain how the blood sugar concentration of the body is controlled and maintained.
11.Describe the difference between type I and type II diabetes.
12.Evaluate the use of biogas in comparison to biofuels.
13.Evaluate the process of deforestation to make way for urban developments for our growing populations.
