What is epidemiology?

Study of patterns and causes of disorders and diseases in defined populations.

Briefly outline an example of a population-based health prevention strategy.

Public policies, regulations and legislation

Education

Awareness camplaigns

Compare thermoregulation in ectotherms and endotherms

Similarities - regulation of body temperature to maintain homeostasis

Differences - ectotherms are reliant on external environments so they may use behavioural adaptation such as moving to the shade.

Endotherms have physiological adaptations such as as shivering or sweating to regulate body temp.

Briefly explain the cause and effect of one disease caused by nutritional deficiency

Anaemia (unable to carry oxygen to tissues) - lack of iron

Blindness - lack of vitamin A

Kwashiorkor (swelling of belly, ankle and feet) - protein deficiency

Describe two mechanisms in plants that allow water balance to be maintained?

What is cancer? Describe the difference between benign and malignant tumors

Cancer is the disease of the body's cells. Normally cells grow and multiply in a controlled way but something causes a mutation to occur in the cells DNA which cause the control to be lost. 

Benign - does not spread

Malignant - spreads to other parts of the body
