Answer;
-The bacterium would exhibit positive chemotaxis.
Explanation;
-Chemotaxis is the movement of cells or organisms in response to chemicals, whereby the cells are attracted (positive chemotaxis) or repelled (negative chemotaxis) by substances exhibiting chemical properties.
Flavonoids play a crucial role as signal molecules in promoting the formation of nodules by symbiotic bacteria commonly known as rhizobia. The roots of leguminous plants use positive chemotaxis to attract rhizobia. Flavonoids are the chemicals associated with attraction of Rhizobium bacteria.
Answer: CheA
Explanation:
Cytokines and chemokines are proteins that bind to other, cells that require specific antibodies to these proteins, making them a form of communication between the system cells immune. That process by which cells are sent to move through a chemical stimulus is called chemotaxis. The internal environment is responsible for the signal transduction part received by the receivers. CheR is a relatively slow enzyme and its main function is to methylate the receptors. It is divided into two domains: one responsible for substrate identification and the other for transferring methyl groups to the receptor.
