6. What do lichen do?

  • Lichen measure the concentration of sulfur dioxide in the atmosphere. If the air is dirty there is lots of lichen
  • Lichen measure the concentration of sulfur dioxide in the atmosphere. If the air is clean there isn't much lichen
  • Lichen measure the concentration of sulfur dioxide in the atmosphere. If the air is clean there is lots of lichen
  • Lichen measure the concentration of pollutants in the atmosphere. If the air is clean there is lots of lichen

7. What are 'extremophiles'?

  • Plants that live in extreme conditions e.g hot volcanic lakes
  • Microorganisms that live in extreme conditions e.g hot volcanic lakes
  • Animals that live in extreme conditions e.g hot volcanic lakes
  • Bacterium that live in extreme conditions e.g hot volcanic lakes

8. What are living indicators, can you give an example?

  • Living indicators/indicator species can be studied to see the effect of human activities. Lichen
  • Living indicators/indicator species can be studied to see the effect of human activities. Leech
  • Living indicators/indicator species can be studied to see the effect of pollution. Lichen
  • Living species can be studied to see the effect of human activities. Lichen

9. What is asexual reproduction?

  • No fusion of gametes, no mixing of chromosomes and no genetic information. They're clones.
  • Fusion of gametes, no mixing of chromosomes and no genetic information. They're clones.
  • Mutations of the parent cell. Shame.
  • The passing on of 'asexual genes' to offspring. Bacteria and Plants do this.

10. What is the order in size in genetic material? (largest to smallest)

  • Nucleus, 23 Pairs of Chromosomes, Gene, DNA Molecules
  • Nucleus, DNA Molecules, Gene 23 Pairs of Chromosomes
  • Nucleus, Gene, 23 Pairs of Chromosomes DNA Molecules
  • DNA Molecules, Nucleus, 23 Pairs of Chromosomes, Gene,

11. What are non living indicators, can you give an example?

  • An example of a non living indicator is a satellite, which measures the temperature of the sea surface.
  • An example of a non living indicator is a satellite, which measures the amount of rainfall
  • An example of a non living indicator is a lichen, which measures the temperature of the sea surface.
  • An example of a non living indicator is a thermometer, which measures the temperature of the sea surface.

12. What elements do plants take in from the soil or air?

  • Carbon, oxygen, nitrogen and sulfur
  • Carbon, oxygen, nitrogen and hydrogen
  • Earth, fire, wind and water
  • Carbon Dioxide, Carbon Monoxide, H2O and Nitrogen

13. How many chromosomes do Gametes have?

  • None because they don't make chromosomes until they have fused with another cell.
  • 46. 23 Pairs of Chromomes.
  • 23. Half the number of a normal cell.
  • 32. One and a half the number of a normal cell

14. Give three examples of living factors.

  • change in infectious disease, number of predators/prey, number of competitors
  • number of prey, number of predators number of competitors
  • type of animals, number of predators/prey, number of competitors
  • habitat conditions, number of predators/prey, number of competitors

15. What do Genes Do?

  • Estimate the development of different characteristics e.g Hair Colour
  • Control the development of different characteristics e.g Hair Colour
  • Control different characteristics e.g Hair Colour
  • Change the development of different characteristics e.g Hair Colour

16. What do animals compete for?

  • territory, food, water and mates.
  • habitat, food, water and mates.
  • freedom, food, water and mates.
  • love, happiness, joy, faith

17. What are detritus feeders?

  • Microorganisms which feed upon dead algae, plants and animal remains.
  • Animals which feed upon dead algae, plants and bacterium remains
  • Animals which feed upon dead algae, plants and animal remains.
  • Dead animals

18. How are desert plants adapted to having little water?

  • Large surface area compared to volume, water storage tissues, maximizing water absorbtion
  • Release antitoxins, water storage tissues, maximizing water absorbtion
  • Small surface area compared to volume, water storage tissues, maximizing water absorbtion
  • Small surface area compared to volume, perspire slowly, maximizing water absorbtion

19. How do plants and animals deter predators?

  • Some plants and animals have armor, others produces poisons, some have warning colours
  • Some plants and animals have shielding, others produces poisons, some have warning colours
  • Some plants and animals have expandable shells, others produces poisons, some have warning colours
  • Some plants and animals have armor, others produces food, some have warning colours

20. How are desert animals adapted to their conditions? (4 things)

  • Large Surface Area compared to volume, efficient with water, good in hot conditions, release poisons
  • Large Surface Area compared to volume, efficient with water, good in hot conditions, camouflage
  • Large Surface Area compared to volume, efficient with water, good in wet conditions, camouflage
  • Small Surface Area compared to volume, efficient with water, good in hot conditions, camouflage
