Q: Applying a pressure greater than the osmotic pressure of a solution will do what? Read this paragraph and choose the correct option from the provided answers: Figure 11.26 Applying a pressure greater than the osmotic pressure of a solution will reverse osmosis. Solvent molecules from the solution are pushed into the pure solvent. Choices: - ultrafiltration - osmosis - normal osmosis - reverse osmosis A:
reverse osmosis

Q: What type of organisms do not need blood? Read this paragraph and choose the correct option from the provided answers: Single-celled organisms do not need blood. They obtain nutrients directly from and excrete wastes directly into their environment. The human organism cannot do that. Our large, complex bodies need blood to deliver nutrients to and remove wastes from our trillions of cells. The heart pumps blood throughout the body in a network of blood vessels. Together, these three componentsblood, heart, and vesselsmakes up the cardiovascular system. This chapter focuses on the medium of transport: blood. Choices: - cold-blooded - vertebrate - marine - single-celled A:
single-celled

Q: Q: Compounds like sodium chloride form structures called what? Read this paragraph and choose the correct option from the provided answers: Compounds like sodium chloride form structures called crystals. A crystal is a rigid framework of many ions locked together in a repeating pattern. Ions are electrically charged forms of atoms. You can see a crystal of sodium chloride in the Figure below . It is made up of many sodium and chloride ions. Choices: - ions - microorganisms - hydrocarbons - crystals A:
A: crystals

Question: Q: What happens when an increase in temperature of a gas in a rigid container happens? Read this paragraph and choose the correct option from the provided answers: An increase in temperature of a gas in a rigid container increases the pressure. Choices: - gas explodes - pressure decreases - container shrinks - pressure increases A:
Answer: pressure increases

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:
**Answer**
double bond

Q: Q: Although humans require it, what accounts for just one percent of all water on earth? Read this paragraph and choose the correct option from the provided answers: All living things need water. For most human uses, water must be fresh. Of all the water on Earth, only 1 percent is fresh, liquid water. Most of the rest of Earth's water is either salt water in the ocean or ice in glaciers and ice caps. Choices: - snow - salt water - glaciers - fresh water A:
A: fresh water
