The diagram shows the nerve pathway when a person touches a sharp pin. Identify structures A and B
sensory neurone and motor neurone
receptor and motor neurone
synapse and motor neurone
receptor and sensory neurone
When the finger touches the sharp pin, the muscle in the arm contracts to pull the arm away.
What type of action is this?
A conscious action
A delayed action
A reflex action
Doctors tested people of different ages to time how long it took between touching a sharp pin and the arm muscle contracting.
At each age they tested five men and calculated a mean value for the time.
The table shows the results.
How much longer does it take for the muscle to contract at 80 years of age compared to at 20 years of age?
Give your answer in seconds.

Luteinising hormone (LH) is a hormone released by the pituitary gland.
What is the function of LH?
Tick one box.
Controls blood glucose concentration
Controls the formation of sperm
Controls the growth of muscles

A flu vaccine is offered to people with a high risk of having a severe illness if they are infected by the flu virus.
What does a flu vaccine contain?
Inactive antibodies
Inactive viruses
White blood cells
A new drug was trialled on 80 healthy volunteers. The volunteers were asked to report any side effects. Based on the results of this trial, what should the drug company do next?
Stop the trial
Test on a small group of patients to find the optimum dose
Test on a large group of patients to see if the drug works on ill people
In the 19th century, Dr Semmelweiss investigated infection in a hospital.
He compared the number of deaths of mothers on two maternity wards.
• On Ward 1, babies were delivered mainly by doctors. These doctors worked on many different wards in the hospital.
• On Ward 2, babies were delivered by midwives. The midwives did not work on other wards.
The bar chart shows the results of his investigations. 600 mothers gave birth on Ward 2 in 1845. How many mothers died from infections on Ward 2 in 1845?

Chickenpox is a disease. Many children get chickenpox.
Most children recover quickly with no serious long term effects.
Chickenpox cannot be treated with antibiotics.
(a) What type of pathogen causes chickenpox?
(a)
People can pay for their child to be vaccinated against chickenpox.
The vaccination stimulates the production of antibodies.
Which part of the blood produces antibodies?
Plasma
Platelets
Red blood cells
White blood cells
The vaccination involves two injections.
The graph below shows how the concentration of antibodies in a child’s bloodstream changes. Suggest on what day the second injection was given.
(a)
On which day is the child’s ability to defend against chickenpox at its peak?
(a)
The diagram shows an athlete running on a treadmill. After running for several minutes, the athlete’s leg muscles began to ache.
This ache was caused by a high concentration of lactic acid in the muscles.
(a) The equation shows how lactic acid is made.
glucose → lactic acid (+ energy)
Name the process that makes lactic acid in the athlete’s muscles.
(a)
Scientists investigated the production of lactic acid by an athlete running at different speeds.
In the investigation:
• the athlete ran on the treadmill at 4 km per hour
• the scientists measured the concentration of lactic acid in the athlete’s blood after 2 minutes of running.
The investigation was repeated for different running speeds.
The graph shows the scientists’ results. How much more lactic acid was there in the athlete’s blood when he ran at 14 km per hour than when he ran at 8 km per hour? Answer = (a) mmol per dm3
Information is passed to target organs in the body by hormones. How do hormones travel around the body?
In the tissue fluid
In the lymphatic system
In the endocrine system
in the blood
Insulin is a hormone. Where is insulin produced?
(a)
Which of the following statements describe the role of insulin in controlling blood sugar levels.
lowers blood sugar level
raises blood sugar level
breaks down glycogen
increases conversion of glucose to glycogen
The diagram shows a cell from a plant leaf. Name structures A and B.

Structure C is a chloroplast. What is the function of a chloroplast?
(a)
The diagram shows two cells, a bacterial cell and a plant cell. Both the bacterial cell and the plant cell contain ribosomes.
What is the function of a ribosome?
site of respiration
site of photosynthesis
site of protein synthesis
