17. Name some Simple Machines

18. Energy Sources (Renewable and non-renewable)
If a resource is renewable, it means we won’t run out of whatever is producing the energy. Examples include hydroelectric energy, solar energy, and wind energy.
If a resource is non-renewable, it means we WILL run out of whatever is producing the energy. Examples include fossil fuels (coal, oil, natural gas) and nuclear energy.

21. Animal and Plant Cells

22. 5 characteristics of living things
Must be able to grow and develop.
Must be able to adapt to environments (physical and behavioural adaptations)
Must be able to reproduce.
Must be able to acquire nutrients.
Must have cells, or be a cell.

23. Physical and Behavioural Adaptations
Most bears are omnivores because they eat both meat and plants. Their sharp teeth help them tear through the flesh of their prey (physical). At the same time, they eat a mixed diet which gives them a wide variety of nutrients (behaviourhal).

24. Osmosis and Diffusion
Osmosis is the movement of water across a semi- permeable membrane, which is done to equalize concentrations.
Diffusion is the movement of a substance from an area of high concentration to low concentration

25. Cellular Respiration and Photosynthesis

26. Reproduction Asexual Reproduction produces identical offspring
Sexual reproduction produces non-identical offspring.
The male gamete is the sperm, the female gamete is the ovum.

28. Horse + Donkey?
