Q: What system can be used by scientists to express very small numbers? Read this paragraph and choose the correct option from the provided answers: Very small numbers can also be expressed using scientific notation. The mass of an electron in decimal notation is 0.000000000000000000000000000911 grams. In scientific notation, the mass is expressed as 9.11 10 -28 g. Notice that the value of the exponent is chosen so that the coefficient is between 1 and 10. Choices: - similar notation - scientific diffusion - certain diffusion - scientific notation A:
scientific notation

Q: The volume of blood each ventricle pumps per minute is called what? Read this paragraph and choose the correct option from the provided answers: Choices: - trauma output - blood output - brain output - cardiac output A:
cardiac output

Q: Q: What is the lightest molecule? Read this paragraph and choose the correct option from the provided answers: Based on their molar masses, hydrogen is the lightest molecule, and oxygen is the heaviest. Because all three volumes are the same, each balloon contains the same number of gas molecules. Therefore, the hydrogen balloon will have the lowest mass, and the oxygen balloon will have the highest. Choices: - oxygen - helium - silicon - hydrogen A:
A: hydrogen

Question: Q: What category of joints is immovable? Read this paragraph and choose the correct option from the provided answers: Classification of Joints on the Basis of Function The functional classification divides joints into three categories: synarthroses, amphiarthroses, and diarthroses. A synarthrosis is a joint that is immovable. This includes sutures, gomphoses, and synchondroses. Amphiarthroses are joints that allow slight movement, including syndesmoses and symphyses. Diarthroses are joints that allow for free movement of the joint, as in synovial joints. Choices: - amphiarthroses - sporozoans - diarthroses - synarthrosis A:
Answer: synarthrosis

Read this paragraph and choose the correct option from the provided answers: agents of fermentation in the production of bread, cheeses, alcoholic beverages, and numerous other food preparations. Secondary metabolites of fungi are used in medicine as antibiotics and anticoagulants. Fungi are used in research as model organisms for the study of eukaryotic genetics and metabolism. Choices: - cloning - condensation - oxidation - fermentation A:

Q: What must molecules have to be cis-trans isomers? Read this paragraph and choose the correct option from the provided answers: Which of the following statements is false? a. Molecules with the formulas CH3CH2COOH and C3H6O2 could be structural isomers. Molecules must have a double bond to be cis-trans isomers. To be enantiomers, a molecule must have at least three different atoms or groups connected to a central carbon. To be enantiomers, a molecule must have at least four different atoms or groups connected to a central carbon. In triglycerides (fats and oils), long carbon chains known as fatty acids may contain double bonds, which can be in either the cis or trans configuration, illustrated in Figure 2.25. Fats with at least one double bond between carbon atoms are unsaturated fats. When some of these bonds are in the cis configuration, the resulting bend in the carbon backbone of the chain means that triglyceride molecules cannot pack tightly, so they remain liquid (oil) at room temperature. On the other hand, triglycerides with trans double bonds (popularly called trans fats), have relatively linear fatty acids that are able to. Choices: - triple bond - last bond - single bond - double bond A:
(A).
double bond
