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.
They're a few ways someone could receive color blindness for one color blindness could be inherited from your parents, and two could also be caused by "abnormal photopigments" which is down in the cells/genes and if deflects will most likely cause color blindness.

The particles that make up matter are the atoms.
Atoms do not change during a chemical change. They do not either during a physical change.
During a chemical change molecules change but not the atoms. The atoms separate from the original molecules and form new molecules. Then moleculas change but atoms remain being the same before and after the chemical change.
For example, atoms of oxygen in molecules of O2 combine with atoms of hydrogen in molecules of H2 and they form the molecules of water H2O.
The atoms of O in O2 are the same atoms of O in H2O and the atoms of H in H2 are the same atoms of H in H2O. The molecules changed, from H2 and O2 to H2O, but the atoms are the same.
