The same, unknown bacteria is isolated from 20 sick individuals. their samples were grown in culture and then placed in 10 healthy mice. those mice started to show signs of a heightened immune response. to determine if the bacteria is pathogenic, what is the next step by using koch’s postulates?

Ans.

Robert Koch gave four postulates to determine whether a given microbe or bacterium is causing a disease or not. These are:

-The bacterium must be found in all organisms with that disease.

-The bacterium can be isolated from the host (infected person) and grown in pure medium.

-The bacterium must cause disease when introduced into a healthy individual.

-The bacterium can be recover from the individual that was infected experimentally and it must be identified as original disease-causing agent.

Thus, according to the Koch postulates, 'the next step would be recovery of pathogenic bacterium from host that was infected experimentally and identification of bacterium to identify it as original disease causative bacterium.'

raits that your monster will have. the dna code for each trait is given, so you will need to go through the process of transcription and translation to determine what protein is being made and then match that with the corresponding trait. you may even include a picture of your monster if you are feeling creati

answer:

the water molecules are transferred from the roots to the stem or top parts of the tall tree because of important properties of water which are adhesion, cohesion and capillary action. cohesion is the property of water molecules keeps water molecules in a combined state by sharing of bonds between them at the atomic level. adhesion allows the interaction of water molecules with other substances or substrate. adhesion will cause the attachment of water molecules to the wall of the vessel (xylem) of the plant. capillary action occurs when the adhesive force to the vessel wall is stronger than the cohesive force between water molecules. capillary action mimics the transfer of water from a tube or pipe. in this way water utilizes its property to transfer water from down to top level of the plant.
