Solutions

1:A - Blue stars are actually the hottest stars! Red stars are the coolest. It’s like when you look at a candle flame, the blue part is usually right in the centre, where the flame is the hottest. , 2:A - Only female mosquitoes bite us to suck our blood for food – they need the protein in our blood to make their eggs. Male mosquitoes drink flower nectar., 3:C - There is a gap of at least 60 million years between dinosaurs becoming extinct and lions starting to appear on Earth. If they had been around at the same time, big dinosaurs like a T rex would have been able to eat lions as they were much bigger., 4:D - Scientists believe the moon was created when the Earth hit another planet about the size of Mars. They melted and re-formed as one planet, with part of the new mass spinning into orbit around the Earth to form the moon. So, without the Earth, it wouldn’t exist., 5:B - Basic bricks are made out of clay – with things like sand, lime or iron oxide added – and are shaped in a mould, although sometimes other machines are used to shape them. They are then dried and fired in a big kiln.
