It’s time for a clean start to the new year! Can you keep your score sheet clean and get 5/5?
Each of these organs does a different job cleaning your blood. The spleen gets rid of old red blood cells, the liver removes toxins, and the kidneys filter out waste that is then removed in your urine.
Soap molecules are fatty on one end, and salty on the other (in this case from the lye). The fatty end sticks to grease and oil, and the salty end lets it dissolve in water!
True! Cleaner wrasses, cleaner gobies and cleaner shrimp all congregate at cleaning stations.
In November 2020, Tasmania became the first state in Australia to reach their 100% renewable energy target. This state can generate all the power it needs from hydroelectricity and wind.
Salt can pull the water out of living cells, in a process called osmosis.
Congratulations! You are a real science whiz!
Oh dear! Better brush up before the next quiz!

Tasmania still has Gas fired power stations. To state that Tasmania runs on 100% renewable is incorrect.

Hi Charles,
Good point! Tasmania does still have gas fired power stations. But it also generates more electricity from renewable sources than they use in total – so it’s kinda over 100%? I guess it’s really hard to be precise when the state has an interconnect to the rest of Australia.
