- salt and sugar are used as preservatives for meat, fruits (as in preserve mango and strawberry jam) and vegetables (as in preserve radish). Explain the practice based on osmosis. plssss help me answer this, thank you.Please explain how different detergents take out proteins selectively out of membrane. (Choose one protein as an example from the figure)What effect does solute concentration have on microbes? How can cells adapt when going from a low solute to a high solute environment and vice versa? What is a compatible solute? What microbial groups have a requirement for high solute concentrations? How do microbes differ in their response to water activity?
- What would happen to chemiosmosis if the pH in the inner membrane space was decreased (lower)?Osmosis, the diffusion of water is distinct from the diffusion of oxygen because a) oxygen is a dissolved gas b) water is a solvent c) water is a large molecule d) water is non-polarIn an investigation of osmosis, apple cores were submerged in different molarity solutions to determine the unknown osmolarity of the apple. To determine the molarity five uniform apple cores were massed before submerging them in different molarity solutions. After 24 hours the apple cores were massed again. Then the percent change in mass was determined for the five uniform apple cores in each molarity solution. c) Describe the environmental conditions taking place in each of the six solutions with the apples
