Autoinducer molecules are signalling molecules that need bacteria. In order for the autoinducer molecules to signal, the bacteria must find a way to initiate the signal and a way to respond to the signal it had created. Autoinducer molecules increase in production as the density of the bacteria cell increases.

Which organelle is responsible for wilting?
makkiz [27]

Vacuole is the answer.

Wilting is the loss of rigidity of non woody parts of plants and occurs when turgor pressure falls. 

The vacuole controls turgor pressure. Turgor pressure dictates the rigidity of the cell and is associated with the difference between the osmotic pressure inside and outside the cell.

When a plant receives adequate amounts of water, the central vacuoles of its cells swell as the liquid collects within them creating a high level of turgor pressure which helps maintain the structural integrity of the plant along with the support of the cell wall.

In the absence of enough water , central vacuoles shrink and turgor pressure is reduced  compromising the plant's rigidity so that wilting takes place.

Tju [1.3M]
Adding large amounts of salt into your body causes your cells to become hypoglycemic (net movement into the cell outweighs net movement out) and causes the cells to boost. Via negative feedback loops, your body feels thirsty to dilute the salt in your cells to return them back to normal concentrations.

What can you conclude is one disadvantage of the arrangement of glucose molecules that gives chitin and cellulose their strength
Lynna [10]
The correct answer is the option B) It does not allow for the accumulation of glycogen and, therefore, limits the organism's mobility.
Explanation:
In cellulose and chitin the arrangement of glycogen in in alternate arrangement that provides the support to the plants that makes it strong and the limits its mobility.
If plants lac their special arrangement of the glycogen in chitin and cellulose the water will flow in and it will not be stand upright.
Thus, the correct answer is option B) It does not allow for the accumulation of glycogen and, therefore, limits the organism's mobility.
