Answer:
selective and differential medium
Explanation:
Based on chemical composition, there are different type of media for the cultivation of bacteria:
- Basal media: culture media that needs no enrichment before being used for bacteria cultivation.
- Enriched media: culture media that are enriched with the addition of blood, serum or egg before being used for culturing.
- Selective media: These are media that selectively favour the growth of a bacterium or group of bacteria over others.
- Differential media: Also known as indicator media. They contain a special substance that changes colour to indicate the presence of a bacterium or group of bacteria.
- Transport media: Media that are used in transporting bacteria from point of collection to where they will be cultured.
- Storage media: These are media that are used to store organisms for future use.
<em>Mannitol salt agar selectively favours the growth of the genus Staphylococcus and inhibits the growth of other organisms. It also contains mannitol which gets fermented and change colour to indicate a particular species of the genus. </em><em>Hence, mannitol salt agar could be classified as a selective and differential medium</em>
I believe the reason as for why experimental procedures are carefully defined is because of D. The clearly defined steps allow other scientists to perform the same experiment.
Kinetic energy is absorbed and converted to potential energy in an endothermic reaction.
Answer:
Innate or natural immunity
Explanation:
Innate immunity is a defense system that we are born with and that protects us against antigens. It is the sum of all defense mechanisms that occur naturally to protect an individual from infectious diseases. They are physiological mechanisms that are present throughout the entire animal kingdom and it is an inherent quality of each species.
They are not specific to a given pathogen, nor do they generate memory
Answer:
C. There are more solvent molecules than solute molecules in the solution.
Explanation:
An equilibrium exist when there is equal distribution of solute and solvent present in a solution otherwise it will be not.
The undistributed solvent and solute concentration undergoes the process of osmosis through which solvent molecules moves from lower to higher concentration through a semipermeable membrane and redistribute the concentration.
The redistribution of molecules reaches the equilibrium, so, until there is more solvent molecules than solute molecules in the solution, there will be no equilibrium.
Hence, the correct option is C.
