Answer the following question given this paragraph: ♦️ Many industrial processes for preparing compounds use "continuous-flow reactors," which are chemical reaction vessels in which the reactants are mixed and allowed to react as they flow along a tube. The products are removed at a certain distance from the starting point, when the reaction is nearly complete. The key operating parameters in a continuous-flow reactor are temperature, reactor volume, and reactant flow rate. As an industrial chemist, you think you have successfully modified a particular process to produce a higher product yield by substituting one reactant for another. The viscosity of the new reactant is, however, greater than that of the initial reactant. Q: Continuous-flow reactors are chemical reaction vessels in which the what are mixed and allowed to react as they flow along a tube? Choices: - reactives - generators - propellants - reactants A:
reactants
Answer the following question given this paragraph: Starvation When the body is deprived of nourishment for an extended period of time, it goes into "survival mode. " The first priority for survival is to provide enough glucose or fuel for the brain. The second priority is the conservation of amino acids for proteins. Therefore, the body uses ketones to satisfy the energy needs of the brain and other glucose-dependent organs, and to maintain proteins in the cells (see Figure 24.2). Because glucose levels are very low during starvation, glycolysis will shut off in cells that can use alternative fuels. For example, muscles will switch from using glucose to fatty acids as fuel. Q: When the body goes into survival mode, it's first priority is to produce enough of which substance for the brain? Choices: - blood - insulin - plasma - glucose A:
glucose
Q: Answer the following question given this paragraph: Chemical reactions also need energy to be activated. They require a certain amount of energy just to get started. This energy is called activation energy . For example, activation energy is needed to start a car engine. Turning the key causes a spark that activates the burning of gasoline in the engine. The combustion of gas won't occur without the spark of energy to begin the reaction. Q: What do chemical reactions need to be activated? Choices: - food - space - products - energy A:
A: energy
Question: Answer the following question given this paragraph: Ultraviolet radiation has the highest energy; infrared the lowest. Q: Ultraviolet radiation has the highest energy; which has the lowest? Choices: - kinetic - nuclear - thermal - infrared A:
Answer: infrared

Answer the following question given this paragraph: Functional Groups Functional groups are groups of atoms that occur within molecules and confer specific chemical properties to those molecules. They are found along the "carbon backbone" of macromolecules. This carbon backbone is formed by chains and/or rings of carbon atoms with the occasional substitution of an element such as nitrogen or oxygen. Molecules with other elements in their carbon backbone are substituted hydrocarbons. The functional groups in a macromolecule are usually attached to the carbon backbone at one or several different places along its chain and/or ring structure. Each of the four types of macromoleculesproteins, lipids, carbohydrates, and nucleic acidshas its own characteristic set of functional groups that contributes greatly to its differing chemical properties and its function in living organisms. Q: Functional groups are groups of atoms that occur within molecules and confer specific chemical properties to those molecules. they are found along the "carbon backbone" of what? Choices: - inorganic molecules - functional molecules - micromolecules - macromolecules A:
**Answer**
macromolecules
Answer the following question given this paragraph: Q: What type of role does cartilage play in the human skeleton? Choices: - variable - important - life saving - insignificant A:
insignificant
