Question 1

Question
FSH (Follicle Stimulating Hormone) is produced by the...
Answer
  • pituitary gland
  • ovaries
  • lungs

Question 2

Question
In which food chain will the greatest proportion of biomass and energy of the plants be passed to humans?
Answer
  • plants --> sheep --> human
  • plants --> grasshoppers --> frogs --> trout --> human
  • plants --> human

Question 3

Question
Which of the following adaptations would a plant in a hot, dry climate NOT have?
Answer
  • Decreased surface area
  • Leaves are flat and wide (large surface area) to try and collect as much water as possible
  • Widespread roots to absorb more water
  • Fleshy, thick stem to absorb more water
  • Thick waxy layer to reduce evaporation, water loss and transpiration
  • Fewer stomata to reduce evaporation, water loss and transpiration

Question 4

Question
A vaccine prevents infection as it contains dead pathogens which are harmless but still have antigens. White blood cells in your body reproduce rapidly upon re-infection. These antibodies kill pathogens.
Answer
  • True
  • False

Question 5

Question
A bird makes a nest with air vents. The bird opens and closes the air vents of the nest at different times of the day. Suggest why the bird opens and closes the air vents. (SELECT THREE)
Answer
  • Opening the vents allows CO2 in
  • Micro-organisms and eggs need oxygen
  • Opening allows release of CO2 from respiration of microorganisms
  • Opening allows heat to come to the eggs
  • Closing retains moisture
  • Opening allows the eggs to get used to the sounds of their surroundings
  • Opening allows the bird to see her eggs

Question 6

Question
The sex of a megapode bird depends on the temperature at which the egg was kept. Suggest why megapode birds control the temperature of their nests.
Answer
  • The megapode prefers girls
  • Maintains sex balance

Question 7

Question
Which of the following is NOT an adaptation an animal living in hot, dry climates (e.g camel) would have?
Answer
  • Long eyelashes to keep dust out of their eyes
  • Nocturnal so they reduce sweat loss as they face the heat of the day for fewer hours
  • Reduced amount of body fat which reduces insulating layer
  • Small feet so there is a smaller surface to get burned by the hot ground

Question 8

Question
What does a vaccine contain?
Answer
  • Antigens
  • Inactive pathogens
  • White blood cells to fight pathogens
  • Platelets

Question 9

Question
Why would an animal be adapted to have large ears?
Answer
  • It lives in cold climates so larger ears would mean a larger surface area to have thick fur on, so the animal could trap more hot air to keep it warm.
  • It lives in hot climates so larger ears would mean a larger surface area : volume ratio so it could lose more heat.

Question 10

Question
Apart from measles, which two other diseases does the MMR vaccine protect against? (SELECT TWO)
Answer
  • Rubella
  • Measles
  • Ebola
  • Flu
  • Mumps
  • Menopause

Question 11

Question
Measles is a virus. Explain why antibiotics cannot be used to treat measles.
Answer
  • When antibiotics and measels combine, they poison you.
  • Antibiotics can't kill viruses because viruses have a hard outer layer which antibiotics aren't strong enough to penetrate.
  • Antibiotics can't kill viruses because viruses live inside cells.

Question 12

Question
Use Lamark's theory to explain how the elephant's trunk evolved. (It stretched)
Answer
  • The mother stretched its offspring's trunks.
  • The mother stretched her own trunk during her lifetime and reproduced
  • The mother asked her offspring to develop longer trunks

Question 13

Question
Suggest ONE advantage to the population as a whole of children having a second MMR vaccination.
Answer
  • Less chance of spread of disease
  • Makes vaccine more effective
  • Makes parents happy

Question 14

Question
Why do antibiotics become less useful at treating an infection if the antibiotic is overused?
Answer
  • Bacteria develops resistance.
  • Bacteria develops immunity.
  • Your body overdoses on antibiotics and it can poison you.

Question 15

Question
A bird collects dead plants and puts them in their nest. The dead plants in the nest decay. The decaying process helps keep the eggs warm for many weeks. Suggest how.
Answer
  • Micro-organisms respire which releases CO2 and heat
  • The dead plants and eggs rub against each other, causing friction, which creates heat
  • Water inside the plants heats up and acts as a hot water bottle

Question 16

Question
Oestrogen inhibits further production of FSH.
Answer
  • True
  • False

Question 17

Question
What was thalidomide originally developed to treat?
Answer
  • Poor sleeping/Insomia
  • Morning sickness
  • Menopause
  • Cold/flu

Question 18

Question
Using a recreational drug may cause the person to become dependent on the drug. What happens in the body to make someone dependent on a drug?
Answer
  • Addiction
  • Changes in chemical processes
  • Habit
  • Drug tastes nice

Question 19

Question
Suggest ONE reason which would need to be considered before a legalisation of a drug.
Answer
  • How high it makes you
  • The long term effects
  • How expensive it is
  • How easy it is to mass produce

Question 20

Question
In the 1800s, many scientists could not decide whether Lamark's theory or Darwin's theory of evolution was the right one. Give TWO reasons why.
Answer
  • Not enough evidence
  • Mechanism of inheritance not known
  • Lamark was not alive so they could not ask him questions
  • Neither of them had a background in science - Darwin was a gardener and Lamark was a musician.
