Answer the following question given this paragraph: Nuclear fission is the splitting of the nucleus of an atom into two smaller nuclei. This releases a great deal of energy. Nuclear power plants use the energy from nuclear fission to generate electricity. Q: What is it called when the nucleus of an atom splits into two smaller nuclei? Choices: - complex fission - cell division - nuclear fusion - nuclear fission A:
nuclear fission
Answer the following question given this paragraph: If two monosaccharides bond together, they form a carbohydrate called a disaccharide . An example of a disaccharide is sucrose (table sugar), which consists of the monosaccharides glucose and fructose ( Figure above ). Monosaccharides and disaccharides are also called simple sugars . They provide the major source of energy to living cells. Q: What do you call the carbohydrate formed when two monosaccharides bond together? Choices: - calcite - glucose - hydroxyl - disaccharide A:
disaccharide
Q: Answer the following question given this paragraph: Human beings are mammals. Like other mammals, we have hair and mammary glands. The subclass in which the human species is classified is the placental mammals. Q: What type of mammals are humans? Choices: - somatic mammals - marsupial mammals - respiratory mammals - placental mammals A:
A: placental mammals
Question: Answer the following question given this paragraph: If plaque blocks coronary arteries that supply blood to the heart, coronary heart disease results. Poor blood flow to the heart may cause chest pain or a heart attack. A heart attack occurs when the blood supply to part of the heart muscle is completely blocked so that cardiac muscle cells die. Coronary heart disease is the leading cause of death in U. S adults. Q: Coronary heart disease is caused when what blocks coronary arteries? Choices: - proteins - carbohydrates - fats - plaque A:
Answer: plaque

Answer the following question given this paragraph: The muscular system consists of all the muscles of the body. Does the word muscle make you think of the bulging biceps of a weightlifter, like the man in Figure below ? Muscles such as biceps that move the body are easy to feel and see, but they aren't the only muscles in the human body. Many muscles are deep within the body. They form the walls of internal organs such as the heart and stomach. You can flex your biceps like a body builder but you cannot control the muscles inside you. It's a good thing that they work on their own without any conscious effort your part, because movement of these muscles is essential for survival. Q: What system consists of all the muscles of the body? Choices: - vascular - digestive - endocrine - muscular A:
**Answer**
muscular

Choices: - c2o - h2o - cl2 - co 2 A:
**Answer**
co 2
