Hormones in plants control growth and development as do those in animals.  The hormone ethylene has the following function:

• Releasing seeds from dormancy

• Root and shoot growth

• Fruit-ripening

One role of many hormones in animals is to maintain homeostasis.  The best definition of homeostasis is:

• The maintenance of constant and stable conditions within the body

• The maintenance of wildly fluctuating conditions within the body

• The maintenance of water levels within the body

Insulin is a hormone which triggers the breakdown of complex sugars into glucose, which are used in the body to produce energy. If an person has trouble producing insulin, he/she suffers from the medical condition known as:

• Lung Cancer

• Diabetes

• Multiple Sclerosis

When you turn on the light in a room that was dark, the pupils of your eyes contract.  In the stimulus response model, what is the response in this scenario

• Light being turned on

• Rod cells in eyes convert light energy to an electrical signal which travels to the brain

• Pupils contract

Which of the following is not a part of the brain?

• Medulla

• Cerebellum

• Ceratonin

Responses in living things can be classified as either innate or learned.  What is the best word below that describes innate behaviours

• Automatic

• Practiced

• Controlled

A)Why do your pupils contract when you walk from a darkened room into the bright sunlight?  b) Can this response be controlled?  Why or why not?   (2 marks)

Imagine a dog running out onto the road in front of a vehicle.  Name three things which could influence the reaction time of the driver (the time between the dog running out and the driver putting his/her foot on the car brake).  (3 marks)

Short term memories can either be transferred to long-term memory or discarded.  What determines whether short-term memories are stored or discarded? (2 marks)

Name three strategies you can use to improve your memory.  Hint- some class activities about remembering objects focused on this. (3 marks)

There are theories that state that birth order has a part to play in forming a person's personality- particularly if a child is born first in the family as opposed to those who are born later. First-born sibblings are often more conscientious and seek parental approval, whilst later born sibblings are often more laid-back and can be better negotiators.  What do you think about this theory? There is no right or wrong answer to this question but you will be marked on the way that you support your argument with reasons and examples. (5 marks)

Explain the role of auxins, gibberellins and cytokinins in plant growth.  (3 marks)

When a person faces a serious threat, the hormone adrenaline is released.  Name five things that occur (in the brain and/or the body) in response to the release of this hormone.  Give a reason why each of these responses may be helpful in an emergency. (5 marks)

A man was stranded in a life raft at sea for a long period of time. The only food he had to eat was the fish he caught. Initially the man ate the fish flesh to survive, but did not eat the other parts as they tasted disgusting to him. As time went on, however he started to seek out the fish organs and eyes, which became tastier to him than the flesh. As it happens the organs and eyes are high in vital vitamins and minerals which are lacking in the fish flesh. What can this story tell us about the functioning of the brain? (2 marks)

• Occipital lobe, frontal lobe, medulla, cerebellum, temporal lobe, parietal lobe

• Frontal lobe, parietal lobe, occipital lobe, cerebellum, medulla, temporal lobe

• Occipital lobe, temporal lobe, medulla, cerebellum, frontal lobe, parietal lobe

What are the two main parts of the nervous system?

• Muscles and blood

• Central Nervous System and Peripheral Nervous System

• Nerves and brain

Detail the main parts of the peripheral nervous system and how this system transfers messages about the outside environment to the brain (3marks)
