The concentration of chemical auto inducers increases with increase in population density
Explanation:
There is something known as Quorum sensing which is a sort of cellular communication in bacteria established through chemical signals. A bacterium is enabled to observe/monitor the environment and thus produce a widespread change in the species with in a community. These sensing processes are effective only when large numbers of cells are doing sensing controlled process together. A bacteria releases auto-inducers whose concentration increases when the population density of cells increase.
"When autoinducers produced by one bacterium cross the membrane of another, they bind to receptors in the cytoplasm. This autoinducer/receptor complex is then able to bind to DNA promoters and activate the transcription of quorum sensing-controlled genes. In this way, individual bacteria within a group are able to benefit from the activity of the entire group."
(VEE-nuh KAY-vuh) A large vein that carries blood to the heart from other areas of the body. The vena cava has two parts: the superior vena cava and the inferior vena cava. The superior vena cava carries blood from the head, neck, arms, and chest.
When a plant cell is placed in a solution with a lower water potential it will lose water osmotically and plasmolyze.
During the process of osmosis water moves from a region of higher water potential to a region of lower water potential.
<u>Loss of water by the plant cells makes it to shrink or reduce in size and consequently, the plasma membrane pulls away from the cell wall, producing plasmolysis.</u>
