What are the features of salmonella prevent it from being phagocytosed?

Salmonella are made of Flagella which prevent it from being phagocytosed.

Flagella is a long filamentous organelle responsible for bacterial motility. falgella are present exteranlly in all three dimensionally in salmonella and it helps salmonella to swim in liquid conditions and rotates the flagella on firm surfaces.

Flagella is known as PAMPs (pathogenic molecular patterns) in salmonella which is used by the host to identify bacteria and activate the immune system of the bacteria.

Hence, rotating or motility and immune function of flagella in salmonella prevent it from being phagocytosed.

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.
