Congratulations! You’re a real science whiz!
Oh dear! Better brush up before the next quiz.
#1. True or false: if you put a sea sponge through a blender and blitzed it into cells, its cells can still recombine to form a new sea sponge.
While some animals can regenerate certain body parts, sea sponges are a rock star when it comes to this. If their individual cells are not damaged by the blending process, sea sponge cells will be able to reconnect with each other and regroup into a brand-new sponge.
#2. Which of the following animals has blue blood?
Crabs have copper pigment in their blood, which turns blue when exposed to air!
#3. Which of the following correctly describes a sea pig?
Sea pigs are deep-sea sea cucumbers and are often found in large groups, gathered around a food source on the ocean floor. They have been found as deep as 6000 metres!
#4. About how much water should a kid aged 9-13 years old drink in a day?
The Victorian Government recommends that kids aged 9-13 should drink 5-6 cups of water each day. Some desert animals, like the Australian hopping mouse, can get all the water they need from food, but sadly humans do not have this ability.
#5. True or false? The tallest human who ever lived was just over 3 metres tall.
False. The American Robert Wadlow was the tallest person ever recorded at 2.72 metres tall. His staggering height was caused by a problem with his pituitary gland, which controls growth.
#6. Which of the following is the deepest place on Earth?
The Mariana Trench in the Pacific Ocean is 11,034 metres deep!
#7. Spitfires or sawfly larvae don’t actually spit fire to fend off hungry birds and other predators, but what do they actually do?
Spitfires regurgitate eucalyptus goop to fend off predators.
#8. True or false: fish skin can be grafted onto human skin to help burn wounds heal.
True! Tilapia fish skin has been used to help patients with burn injuries recover faster.
#9. About how many websites currently exist on the web?
As of 2023, there are about 1,100,000,000 websites on the internet! But 82% of these websites are inactive, meaning only about 200 million websites are actively maintained and visited.
#10. True or false: cows have 800 different blood types.
True! Cows have 11 major blood groups, but each group has lots of subtypes.
