HACTEHA [7]3 years ago

A solution to be isotonic refers to b) The concentration of solute in the environment and the concentration inside the cell are at equilibrium.

  • Isotonic solution is the solution that have equal concentration of solute on both sides of the solution separated by a membrane.
  • If a cell is kept in an isotonic solution that means the concentration of the solute inside the cell is the same as that of the outside then the movement of solvent does not occur between the cell and the external environment.
  • The osmotic pressure inside the cell and outside the cell across the semipermeable membrane of the cell becomes the same due to equal concentration of the solute on each side.

0.9% normal saline is an example of isotonic solution.

Which of these actions is the best way for an individual to conserve water?
BigorU [14]

Answer: B. Take short showers instead of baths.

Explanation:

The water is the most important non-living environmental factor which is the main requirement for survival of every living being. Even though water is a renewable resource which can be replenish by the mode of water cycling in nature but with the increase in the global population the demand of freshwater has increased. Also with the increase in the causes and sources of water pollution the levels of freshwater sources are decreasing. Therefore, the issues of water conservation should be taken into consideration.

According to the given situation, if an individual needs to conserve water, take short showers instead of baths is the correct option because of the fact that short showers will prevents the wastage of large amount of water which could be wasted while taking baths.

THe hydrolysis of triglycerides on a spirit blue agar plate most closely resembles that of __________ hemolysis on a blood agar
patriot [66]

The hydrolysis of triglycerides on a spirit blue agar plate most closely resembles that of beta hemolysis on a blood agar plate.


The hydrolysis of triglycerides on a spirit blue agar plate is used for identifying bacteria based on what organic compounds they can break down, in this case lipids. Spirit blue agar is a medium that contains a supply of lipids. If bacteria have lipase, the enzyme capable of breaking down lipids spirit blue agar will be digested and it will appear as a halos around colonies of bacteria that make lipase.


The ability of bacterial colonies to induce hemolysis (the breakage of red blood cells) when grown on blood agar is used to identify microorganisms. Beta hemolysis is a complete lysis of red blood cells and in the blood agar, that area under the colonies that do the hemolysis appears lightened and transparent.

Small molecules and proteins can act as cellular communication signals by binding to cell receptors. a protein binds to its rece
mariarad [96]

The correct answer is signal transduction.

Signal transduction also called cell signaling refers to the conduction of molecular signals from the external of the cell to its internal. The signals perceived by the cells must be conducted efficiently into the cell to make sure an effective response. This step is stimulated by cell-surface receptors.

There are three phases in the procedure of communication or cell signaling, that is, reception, transduction, and response.
