The Sun is a star! Stars produce their own energy through nuclear fusion.
#4. Scientists consider 6 elements to be the fundamental building blocks of life, required for life to start. Which of the following elements is a fundamental building block?
Carbon can have up to 4 bonds with other atoms, making it the backbone of the organic molecules making life possible. The 6 fundamental building blocks are sulfur, phosphorus, oxygen, nitrogen, carbon, and hydrogen.
#5. Who, in 1706, first gave the Greek letter π its current mathematical definition?
British mathematician William Jones used the symbol π to represent the number 3.14159… in 1706. It was later popularized by Swiss mathematician Leonhard Euler.
#6. The Great Barrier Reef is built by billions of tiny organisms called coral polyps. Coral polyps belong to which group of living things?
Coral are marine invertebrates, meaning they are sea animals that don’t have a backbone. They are closely related to sea anemones and are in the same large group (phylum) as jellyfish.
#7. There are 9 essential amino acids that we have to eat, because our bodies can’t make them. Which of the following vegetarian meals contain all 9 essential amino acids?
All of these dishes combine incomplete sources to get all 9 essential building blocks of proteins (also called amino acids). There are a few vegetarian foods that on their own deliver all 9, including soybeans, quinoa, and pistachios.
#8. True or false: if you put a sea sponge through a blender and blitzed it into cells, its cells can still recombine to form a new sea sponge.
While some animals can regenerate certain body parts, sea sponges are a rock star when it comes to this. If their individual cells are not damaged by the blending process, sea sponge cells will be able to reconnect with each other and regroup into a brand-new sponge.
#9. It’s at the start of every link, but what does HTTP stand for?
The Hypertext Transfer Protocol (HTTP) forms the foundation of communication for the World Wide Web. It allows for hypertext documents, which contain links to other webpages.
