Answer ✔: 1. CT Scan: A computerized tomography (CT) scan combines a series of X-ray images taken from different angles around your body and uses computer processing to create cross-sectional images (slices) of the bones, blood vessels and soft tissues inside your body. CT scan images provide more-detailed information than plain X-rays do.A CT scan has many uses, but it's particularly well-suited to quickly examine people who may have internal injuries from car accidents or other types of trauma. A CT scan can be used to visualize nearly all parts of the body and is used to diagnose disease or injury as well as to plan medical, surgical or radiation treatment.

2. Great Barrier Reef: The Great Barrier Reef is the world's largest coral reef system composed of over 2,900 individual reefs and 900 islands stretching for over 2,300 kilometres (1,400 mi) over an area of approximately 344,400 square kilometres (133,000 sq mi). The reef is located in the Coral Sea, off the coast of Queensland, Australia.The Great Barrier Reef is a site of remarkable variety and beauty on the north-east coast of Australia. It contains the world's largest collection of coral reefs, with 400 types of coral, 1,500 species of fish and 4,000 types of mollusc.

3. Dragon Blood Trees: The Dragon's Blood Tree is named for unique red sap.This red sap forms a resin that was a prized commodity in ancient times. Romans and other old civilizations used it as medicine and as a red dye.Native to a single island in the Socotra archipelago, off the coast of Yemen in the Arabian Sea, the extraordinary-looking dragon's blood tree, which is classified as “vulnerable to extinction,” can grow to more than 30 feet in height and live for 600 years.
