Question 3 of 28

1

Which of the following adaptations would a plant in a hot, dry climate NOT have?

Select one of the following:

  • 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

  • Fewer stomata to reduce evaporation, water loss and transpiration

Explanation

Question 4 of 28

1

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.

Select one of the following:

  • True
  • False

Explanation

Question 5 of 28

1

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)

Select one or more of the following:

  • 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

Explanation

Question 6 of 28

1

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.

Select one of the following:

  • The megapode prefers girls

  • Maintains sex balance

Explanation

Question 7 of 28

1

Which of the following is NOT an adaptation an animal living in hot, dry climates (e.g camel) would have?

Select one of the following:

  • 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

Explanation

Question 8 of 28

1

What does a vaccine contain?

Select one of the following:

  • Antigens

  • Inactive pathogens

  • White blood cells to fight pathogens

  • Platelets

Explanation

Question 9 of 28

1

Why would an animal be adapted to have large ears?

Select one of the following:

  • 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.

Explanation

Question 10 of 28

1

Apart from measles, which two other diseases does the MMR vaccine protect against? (SELECT TWO)

Select one or more of the following:

  • Rubella

  • Measles

  • Ebola

  • Flu

  • Mumps

  • Menopause

Explanation

Question 11 of 28

1

Measles is a virus.

Explain why antibiotics cannot be used to treat measles.

Select one of the following:

  • 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.

Explanation

Question 12 of 28

1

Use Lamark's theory to explain how the elephant's trunk evolved. (It stretched)

Select one of the following:

  • 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

Explanation

Question 13 of 28

1

Suggest ONE advantage to the population as a whole of children having a second MMR vaccination.

Select one of the following:

  • Less chance of spread of disease

  • Makes vaccine more effective

  • Makes parents happy

Explanation

Question 14 of 28

1

Why do antibiotics become less useful at treating an infection if the antibiotic is overused?

Select one of the following:

  • Bacteria develops resistance.

  • Bacteria develops immunity.

  • Your body overdoses on antibiotics and it can poison you.

Explanation

Question 15 of 28

1

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.

Select one of the following:

  • 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

Explanation
