Rio Bio 156 Exam 1 2023 With 100% Complete Solutions

Explain how electron configuration influences the chemical properties of an atom. {Ans: Each cloud can hold a determinant number of electrons. When the electron number changes, ions are formed. The number of electrons influences the bonding between atoms.}Describe the structure and function of cell walls. {Ans: Protects, structurally supports cell}By definition, distinguish between a population, a community, and an ecosystem. {Ans: 1. Population: multiple organisms in a single spot 2. community: is made up of populations of different organisms 3. ecosystem: is the interactions between the community and the non-living environment that surrounds it}induced-fit model {Ans: Substrate binding to an active site improves the fit between the two.}Distinguish between exocytosis and endocytosis. {Ans: endocytosis: Process by which a cell takes in a small amount of extracellular fluid (and its contents) by the ballooning inward of the plasma membrane. exocytosis: Process by which a cell expels a vesicle's contents to extracellular fluid.}activation energy {Ans: the minimum amount of energy required to get a chemical reaction started.}
