Solutions

1:A - Phones can tap into data that comes from satellites and weather stations, tracking temperature, wind and rain. The phone uses your location to show the forecast where you are., 2:D - Your skin starts just beneath the surface of your body, where new skin cells grow. As they form, outer cells are shed, so over time the new skin becomes the outermost layer., 3:D - Australia’s National Koala Monitoring Program said in 2024 there were about 224,000 to 524,000 koalas left. Sadly, numbers are dropping due to habitat loss, bushfires and diseases., 4:A - Most natural things, like trees and plants, are green because of the pigment chlorophyll. It mainly absorbs red and blue light, and reflects green light – that’s why plants look green. This is part of a process called photosynthesis and helps the plant make food., 5:B - Much of your heart is made up of tissue called cardiac muscle, which can contract (squeeze) to pump blood. Your heart also has special cells that help it beat in a regular rhythm, and its outer layer is covered with a thin lining to protect it.
