Ques: Q: All planets exhibit the same or nearly the same direction and shape of what path around the sun? Read this paragraph and choose the correct option from the provided answers: To figure out how the solar system formed, we need to put together what we have learned. There are two other important features to consider. First, all the planets orbit in nearly the same flat, disk-like region. Second, all the planets orbit in the same direction around the Sun. These two features are clues to how the solar system formed. Choices: - revolution - ellipse - nucleus - orbit A:
Ans: orbit

Ques: Q: Hydrogen sulfide is a noxious and toxic gas produced from decaying organic matter that contains what? Read this paragraph and choose the correct option from the provided answers: Hydrogen sulfide is a noxious and toxic gas produced from decaying organic matter that contains sulfur. A lethal concentration in rats corresponds to an inhaled dose of 715 molecules per million molecules of air. How many molecules does this correspond to per mole of air? How many moles of hydrogen sulfide does this correspond to per mole of air?. Choices: - tin - methane - helium - sulfur A:
Ans: sulfur

Ques: Q: Introduction genetics is the study of what? Read this paragraph and choose the correct option from the provided answers: 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. Choices: - biology - variability - obesity - heredity A:
Ans: heredity

Ques: Q: What organ creates bile? Read this paragraph and choose the correct option from the provided answers: The liver is an organ of both digestion and excretion. It produces a fluid called bile , which is secreted into the duodenum. Some bile also goes to the gall bladder , a sac-like organ that stores and concentrates bile and then secretes it into the small intestine. In the duodenum, bile breaks up large globules of lipids into smaller globules that are easier for enzymes to break down. Bile also reduces the acidity of food entering from the highly acidic stomach. This is important because digestive enzymes that work in the duodenum need a neutral environment. The pancreas contributes to the neutral environment by secreting bicarbonate, a basic substance that neutralizes acid. Choices: - kidney - pancreas - heart - liver A:
Ans:
liver
