Transcript

  1. Adaptations in animals To describe how animals are adapted to live in their particular habitat and that there is a relationship between body size and surface area to volume ratio
  2. Fertilisation In sexual reproduction, fertilisation happens when a male and a female sex cell join together.
  3. Fertilisation questions female gamete e…. new cell male gamete s……….. z……… f……………
  4. Fertilisation answers female gamete egg new cell male gamete sperm zygote fertilisation
  5. Variations AQA Science © Nelson Thornes Ltd 2006  There are variations between members of the same species. Because of these variations, some individuals are more successful than others. In harsh conditions, the fittest survive.
  6. Variations questions AQA Science © Nelson Thornes Ltd 2006  All ladybirds taste disgusting because they contain a ……………. chemical. Because of ………….., some ladybirds contain more poison than ………. . In areas where there are many birds, the more poisonous ladybirds are more likely to ………… . poisonous variation others survive Corel 103(NT)
  7. Sexual reproduction In sexual reproduction, genetic information from two parents is mixed to make a new plan for the offspring. This leads to variation between members of a species.
  8. Sexual reproduction questions <ul><li>When eggs and sperm (………….) are made </li></ul><ul><li>genetic information from two parents is ……… </li></ul><ul><li>so the new cell (………..) formed contains a new plan for the offspring. </li></ul><ul><li>This ………….. means that every offspring is different. </li></ul>gametes mixed zygote variation
  9. Environmental and inherited variation AQA Science © Nelson Thornes Ltd 2006  Variation between organisms of the same species has environmental as well as inherited causes.
  10. Environmental and inherited variation AQA Science © Nelson Thornes Ltd 2006  ……… .. variation acts here baby adult ……………… .. variation acts here to make each adult different! egg sperm to make each baby different! genetic environmental
  11. Selective breeding You can produce animals and plants with the features you want by a process called selective breeding.
  12. Selective breeding questions <ul><li>Parents with the best wool texture are …………. </li></ul><ul><li>They are ……... </li></ul><ul><li>………… ... with the best wool texture are selected and bred in turn. </li></ul><ul><li>At each …………….. the wool texture improves. </li></ul>selected bred Offspring generation Corel 602(NT)
  13. Sustainable development Sustainable development (when we replace the plants and animals we use) is becoming more and more important. There are ways in which we can protect living organisms and the environment they live in.
  14. Sustainable development questions Name some more good ways of protecting the environment with sustainable development. Create National Parks Replant trees we cut down Recycle as much waste as we can Energy efficiency
  15. Competition Competition for the resources available is one thing which affects the size of populations of animals and plants.
  16. Toxic build-up Toxic (poisonous) materials that we produce can build up in food chains and cause big problems.
  17. Toxic build-up questions Find out what happened when mercury was concentrated in the food chains in Minamata Bay
