Answer the following question given this paragraph: Introduction Genetics is the study of heredity. Johann Gregor Mendel set the framework for genetics long before chromosomes or genes had been identified, at a time when meiosis was not well understood. Mendel selected a simple biological system and conducted methodical, quantitative analyses using large sample sizes. Because of Mendel's work, the fundamental principles of heredity were revealed. We now know that genes, carried on chromosomes, are the basic functional units of heredity with the ability to be replicated, expressed, or mutated. Today, the postulates put forth by Mendel form the basis of classical, or Mendelian, genetics. Not all genes are transmitted from parents to offspring according to Mendelian genetics, but Mendel's experiments serve as an excellent starting point for thinking about inheritance. Q: Introduction genetics is the study of what? Choices: - biology - variability - obesity - heredity A:
heredity
Q: Answer the following question given this paragraph: Athletics are very competitive these days at all levels, from school sports to the pros. Everybody is looking for that edge that will make them faster, stronger, more physically fit. One approach taken by many athletes is the use of amino acid supplements. The theory is that the increase in amino acids in the diet will lead to increased protein for muscles. However, the only real benefit comes to the people who make and sell the pills. Studies have not showed any advantage obtained by the athletes themselves. You're much better off just maintaining a healthy diet. Q: Which is the best way to maintain a strong, fit body? Choices: - bodybuilding - regular exercising - being a vegetarian - a healthy diet A:
A: a healthy diet
Question: Answer the following question given this paragraph: Nonmetals are elements that do not conduct electricity. They are the second largest class of elements. Nonmetals are also poor conductors of heat. The majority of nonmetals are gases. Solid nonmetals are dull and brittle. Q: Elements that do not need to conduct electricity are known as what? Choices: - alloys - carbonates - silicates - nonmetals A:
Answer: nonmetals

Answer the following question given this paragraph: Ingestive protists ingest, or engulf, bacteria and other small particles. They extend their cell wall and cell membrane around the food item, forming a food vacuole. Then enzymes digest the food in the vacuole. Q: What substances digest the food in the vacuole of an ingestive protist? Choices: - carbohydrates - lipids - hormones - enzymes A:
**Answer**
enzymes
Q: Answer the following question given this paragraph: During anaphase , sister chromatids separate and the centromeres divide. The sister chromatids are pulled apart by the shortening of the spindle fibers. This is like reeling in a fish by shortening the fishing line. One sister chromatid moves to one pole of the cell, and the other sister chromatid moves to the opposite pole. At the end of anaphase, each pole of the cell has a complete set of chromosomes. Q: During which phase do sister chromatids separate and the centromeres divide? Choices: - cell phase - gap cycle - passivation - anaphase A:
A: anaphase
