How do fertility drugs help women become pregnant in the natural way?

• Oestrogen is given to the patient

• The fertility drugs FSH and LH are given to the patient

• Testosterone and LH are given to the patient

What are three examples of conditions controlled by homeostasis in the body?

• Body temperature, nervous and chemical responses

• Blood glucose, body temperature and nervous responses

• Blood glucose concentration, body temperature and water levels

What is included in the central nervous system (CNS)?

• Brain and spinal cord

• Spinal cord and all neurones in the body

• Brain and all neurones in the body

What is the purpose of the Pancreas?

• To secrete urine

• To control body water levels

• Maintain a constant amount of glucose

• To maintain body temperature

What is the best definition of homeostasis?

• keeping a constant temperature

• taking in oxygen and getting rid of carbon dioxide

• maintenance of a constant internal environment

• getting rid of waste

Why is it important to maintain a constant body temperature?

• to maintain the optimum temperature for enzymes

• so that we have enough energy to move

• to stop the multiplication of bacteria in the body

• so that we don't get cold
