Question: Answer the following question given this paragraph: Mercury is the smallest planet. It has no moon. It is also the planet closest to the Sun. Pictured below is the surface of Mercury covered with craters ( Figure below ), like Earth's Moon. Many of the impact craters are billions of years old. This means that Mercury hasn't changed much geologically for billions of years. It has no plate tectonics. With only a trace of an atmosphere, it has no weather to wear down the ancient craters. Q: What is the name of the smallest planet in our solar system, which is also nearest to the sun? Choices: - mars - jupitor - earth - mercury A:

Answer the following question given this paragraph: Hydrocarbons are molecules that contain only carbon and hydrogen atoms. Because each carbon atom can form covalent bonds with up to four other atoms, very large and complex molecules can be formed just from these two elements. Hydrocarbons in which all carbons are connected by single bonds are known as alkanes . If a C=C double bond is present, the compound is now an alkene . A triple bond between two carbons (CC) makes the compound an alkyne . Hydrocarbons can also be broadly classified as either saturated , which means they contain no multiple bonds, or unsaturated , which means they contain at least one double or triple bond. Q: Hydrocarbons in which all carbons are connected by single bonds are called? Choices: - acids - enzymes - lipids - alkanes A:
**Answer**
alkanes
