Answer the following question given this paragraph: Hundreds of thousands of asteroids have been found in our solar system. They are still being discovered at a rate of about 5,000 new asteroids per month! The majority are located in between the orbits of Mars and Jupiter. This region is called the asteroid belt , as shown in Figure below . There are many thousands of asteroids in the asteroid belt. Still, their total mass adds up to only about 4 percent of Earth's Moon. Q: What two planets is the asteroid belt found between? Choices: - mars and venus - earth and venus - saturn and uranus - mars and jupiter A:
mars and jupiter
Answer the following question given this paragraph: Your heart pumps blood around your body. But how does your heart get blood to and from every cell in your body? Your heart is connected to blood vessels such as veins and arteries. Organs that work together form an organ system . Together, your heart, blood, and blood vessels form your cardiovascular system . Q: What organ system is comprised of your heart, blood, and blood vessels all working together? Choices: - thoraxic system - nervous system - digestive system - cardiovascular system A:
cardiovascular system
Q: Answer the following question given this paragraph: 1. The first step in eukaryotic cell division, as it is in prokaryotic cell division, is DNA replication. As you can see in Figure below , each chromosome then consists of two identical copies. The two copies are called sister chromatids. They are attached to each other at a point called the centromere. Q: Dna replication is the first step in what process for both eukaryotic and prokaryotic cells? Choices: - cell death - cell growth - cell transfer - cell division A:
A: cell division
Question: Answer the following question given this paragraph: Q: Inducible enzymes usually function in what type of pathways? Choices: - enzymatic - anabolic - biogenic - catabolic A:
Answer: catabolic

Answer the following question given this paragraph: Aerobic respiration , which takes place in the presence of oxygen, evolved after oxygen was added to Earth's atmosphere. This type of respiration is useful today because the atmosphere is now 21% oxygen. However, some anaerobic organisms that evolved before the atmosphere contained oxygen have survived to the present. Therefore, anaerobic respiration , which takes place without oxygen, must also have advantages. Q: Anaerobic respiration takes place without what? Choices: - nitrogen - movement - carbon - oxygen A:
**Answer**
oxygen
Answer the following question given this paragraph: An enzyme is an organic catalyst produced by a living cell. Enzymes are such powerful catalysts that the reactions they promote occur rapidly at body temperature. Without the help of enzymes, these reactions would require high temperatures and long reaction times. The molecule or molecules on which an enzyme acts are called its substrates. An enzyme has an active site where its substrate or substrates bind to form an enzymesubstrate complex. The reaction occurs, and product is released:. Q: An enzyme is an organic catalyst produced by what? Choices: - DNA - the liver - amino acid - living cell A:
living cell
