Solutions

1:A - Slugs are not waterproof. They dry out quickly and need to conserve moisture, so they come out at night when temperatures are cooler. When the air is dry they can put a cocoon around themselves and wait until it rains., 2:B - Bacteria and diet can make poo smell. When bacteria in your body breaks down food you eat, gases like hydrogen sulfide might make poo smell. Normally it should not smell too bad., 3:B - Vienna! The first croissant-type food was made in Austria, where it was called the kipferl. , 4:B - Pigments in flowers, called anthocyanins and carotenoids, are usually what give flowers their colours. Flower colour can also be affected by things such as the amount of light they receive and the temperature around them., 5:A - Lava is hot because it comes from at least 100km or deeper inside the Earth where it is super-hot – so hot that rocks melt to make a substance called magma. Magma rises, and eventually some of it pushes through vents and fissures to the Earth’s surface. Magma that has erupted is called lava.
