Answer:
Many biofilm-specific phenotypes are controlled by "quorum sensing." This system allows bacteria to regulate gene expression according to the concentration of <u>bacteria</u>.
Explanation:
Quorum sensing is basically a process which depends upon the <u>density dependent communication </u>of bacteria. Higher the number of bacteria, more will be the communication. Example of quorum sensing is biofilms which grow on various surfaces.
Some auto-inducers like peptides and N-acyl homoserine lactone are produced by bacteria during this process which in turn activate some transcription factors to cause gene expression.
In bacteria, it mainly serves the purpose of bioluminescence, sporulation and nitrogen fixation.
Answer:
False.
Explanation:
Since thermal means heat, then this statement is false.
You would need to cool the gas (or lose thermal energy) for a gas to become a liquid.
To go from a liquid to a gas, then you would apply thermal energy (or the liquid would have to gain thermal energy).
B. The reason we have the nomenclature (name) system we have is because it can reveal more about the animal. For example, it tells our genus and our species. Just the common name can apply to anything
True, industrialized areas have more man-made factories and facilities which let off pollution
