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:
The answer is MRI.
Explanation:
The method used to get the best quality images of the brain's soft tissue is MRI (Magnetic Resonance Imaging) scans. One of the most common benefits of using MRI is because it does not use x-rays therefore does not emit radiation that is harmful to the subject, which is one of the reasons that it provides high-quality images.
I hope this answer helps.
The Domain Archaea<span> wasn't recognized as a major domain of life until quite recently and,
</span>The Eukaryota Domain include the organisms that most people are most familiar with - all animals, plants, fungi, and protists and animals have hair and skeleton.
