Bacteria that form biofilms secrete molecules that they use to communicate with each other. These locally-produced molecules all
ow the individual cells to sense each other, a phenomenon called quorum sensing and, in this manner, coordinate their behaviors to perform activities that are required for biofilm formation. To form a biofilm, the bacteria adhere to a surface and aggregate, forming spore-like structures. This makes them very resistant to antibiotic treatments. This phenomenon illustrates the ability of the cells to:
Communicate with one another by means of solvent variables.
Explanation:
Numerous microbes are known to coordinate their pleasant activities and physiological techniques through a framework called majority detecting in which bacterial cells talk with each other by releasing, detecting and responding to minimal diffuse-able banner particles. The limit of microscopic organisms to give and carry on as a get-together for social correspondences like a multi-cell animal has given basic favorable circumstances to microbes in have colonization, plan of bio-films, guard against contenders, and acclimation to developing circumstances. Basically, various QS-controlled activities have been related with the hurtfulness and pathogenic capacity of microscopic organisms
This phenomenon illustrates the ability of the cells to share information and adjust gene expression accordingly.
Explanation:
As bacterial population density increases, the bacteria monitor this information to track changes in their cell numbers and collectively alter gene expression.
The processes that lead to most genetic variation in sexually reproducing organisms are as follows; - cross over - independent orientation of chromosomes in meiosis - random fertilization The behavior of chromosomes during fertilization and meiosis is what brings most of the variation that arises each generation during sexual reproduction.
