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: There are two possible effective choices
A. Start contour plowing on the slopes where landslides happen.
E. Reduce the slopes where landslides occur.
Explanation:
Plowing can help flow water through the slopes instead of it all building up in one area all at once. But reducing the slopes can slow landslides due to the smaller incline, but will not completely get rid of them.
Because your memory of physical pain and your reaction to pain is what you remember. not the pain itself, but your reaction to the pain. hope this is helpful..
