#5. True or false? A large, carnivorous koala-relative once roamed Australia.
True. Thylacoleo was a koala-relative that evolved to become a large and terrifying meat-eating predator. It weighed over 100 kilograms and could climb trees.

#7. Which of the following is NOT found in human blood?
Green blood cells. Red blood cells carry oxygen, white blood cells form the immune system, and platelets create clots at injury sites, so you don’t lose too much blood.
#8. What part of your eye senses colour?
The retina is where all your light-sensing nerves are, including the colour-sensing ones. The eyelid just covers the eye. The iris is the colourful part of your eye but it does not sense colour.
#9. Bose-Einstein condensates are sometimes known as a fifth state of matter, where particles are cooled to very cold temperatures close to absolute zero. Do you know how many degrees is absolute zero?
Theoretically, absolute zero is the temperature where particles stop moving and it’s the coldest temperature possible. The Celsius scale was changed in 1954 so that absolute zero was exactly –273.15 °C.
#10. Which of the following gases directly damages the ozone layer?
Chlorofluorocarbons, before they were banned, were used in aerosol cans and refrigeration. The chloride atoms in these gases destroyed ozone (O3) molecules.
