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
