Explain how Pollination is different from the process of Fertilisation.
Pollination is where pollen from the anther of one flower travels to the stigma of another flower.
Fertilisation is where pollen on the stigma grows a tube down the style until it reaches an ova in the ovary. This changes the ova into a seed.

Discuss the 3 adaptations; structural, behavioural and functional.
Structural adaptations are parts of the living organism that help it survive. Some examples are claws, teeth, fur, scales, and large leaves.
Physiological adaptations are chemicals or internal organs which help an organism survive. Some examples are venom, a powerful heart, and sweet sugary nectar.
Behavioural adaptations are actions taken by the organism to help it survive. Some examples are hunting at night, living in a herd, and looking after their young.

Explain the steps in the water cycle
1 Evaporation: liquid to gas; water being heated by sun
2 Condensation: gas cooled down to make clouds
3 Precipitation: when clouds get too heavy, it rains
4 Collection: collection of water through run off

Explain why a blue towel looks black when you shine a red light on it.
White light is made of ROYGBIV which are each different wavelengths. The red filter absorbs every colour except for red, which it transmits. A blue towel only reflects blue light and absorbs all other colours. Because only red light passes through the filter, and the blue towel absorbs red light, no light is reflected back to your eye, making the towel look black.
