Q: Answer the following question given this paragraph: In other covalent bonds, electrons are shared equally. These bonds are called nonpolar covalent bonds. Neither atom attracts the shared electrons more strongly. As a result, the atoms remain neutral in charge. The oxygen (O 2 ) molecule in the Figure below has two nonpolar bonds. The two oxygen nuclei have an equal force of attraction for their four shared electrons. Q: How are electrons shared in covalent bonds? Choices: - randomly - orderly - unequally - equally A:
A: equally

Answer the following question given this paragraph: The star constellation "Orion, The Hunter". Orion is one of the most beautiful of all constellations, and one of the easiest to find. It looks like a large (slightly twisted) rectangle high in winter's south-southeastern sky. Two of the brightest stars in the evening sky lie at opposite corners of the rectangle: bright orange-red Betelgeuse at the northeastern corner (upper left in the photo) and even brighter Rigel at the southwest (lower right in the photo). Betelgeuse is at least 300 times the Sun's diameter, and perhaps much more. It puts out about 100,000 times more energy than the Sun does. When Betelgeuse dies, it will create a fireball that will briefly outshine billions of normal stars. Betelgeuse is a red giant and Rigel is a blue giant. Q: Which constellation looks like a rectangle high in winter's south-southeastern sky? Choices: - Caelum - Apus - Andromeda - orion A:
**Answer**
orion
Answer the following question given this paragraph: Biochemical compounds make up the cells and tissues of organisms. They are also involved in life processes, such as making and using food for energy. Given their diversity of functions, it's not surprising that there are millions of different biochemical compounds. However, they can be grouped into just four main classes: carbohydrates, proteins, lipids, and nucleic acids. The classes are summarized in Table below and described in the rest of this lesson. Q: What type of compounds make up the cells and tissues of organisms? Choices: - hormonal compounds - productive compounds - organic compounds - biochemical compounds A:
biochemical compounds
