Solutions

1:A - Based on the amount of the plant it would take to kill a human, the castor oil plant is the deadliest. It would take 70 micrograms of castor bean to kill an adult – that’s up to eight of its tiny seeds!, 2:B - Cats have one life, just like us! The idea that they have nine lives could have come about because when they fall from a height, they usually land on their feet. , 3:D - Coffee contains caffeine, which makes you feel energised. But caffeine is addictive. If you drink a lot and then suddenly stop, you can experience withdrawal symptoms, like headaches, grumpiness and tiredness., 4:D - Nocturnal animals tend to have big eyes, as well as cells that can pick up scattered, dim light. Some even have a mirror-like layer in their eyes, which makes the most of any light there is by reflecting it within the eye., 5:B - First, blood rushes to broken bone and forms a protective layer. Over time, this layer hardens into bone. During this healing stage, it’s important that you don’t move the broken bone around, so a doctor usually puts a cast on it to keep it still while new bone forms.
