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.
These are some of the things that may cause denaturation:
external stress or compound such as a strong acid<span> or </span>base<span>, a concentrated </span>inorganic<span> salt, an </span>organic<span> solvent (e.g., </span>alcohol<span> or</span>chloroform<span>), radiation or </span>heat<span>.
</span>If this happens, cell activity may be disrupted and it can die.
Answer:
The nervous system takes in information through our senses, processes the information and triggers reactions, such as making your muscles move or causing you to feel pain. For example, if you touch a hot plate, you reflexively pull back your hand and your nerves simultaneously send pain signals to your brain.
