Default network
When the brain is unoccupied, an fMRI indicates that blood continues to flow via a web of brain regions called the default network.
The default network is a web of brain regions that have activity that corresponds greatly with each other and different from other networks within the brain. The default network is active when an individual's attention is not concentrated on the external environment and it is measured with the functional magnetic resonance imaging technique (fMRI).
Answer:

Because your not close enough to get the virus if you have a mask, but if you don’t wear a mask, social distance is irrelevant because the sneeze or cough travels more that 100 feet and then your caught with the virus.
Explanation:
Answer:
The visible DNA fingerprint can help extract DNA which, after analysis, can accurately identify the suspect or perpetrator of the crime.
Explanation:
DNA Fingerprinting:
- DNA fingerprinting is a molecular analysis tool that can help identify a suspect in a crime through DNA extracted from fingerprints.
- Specific patterns in the DNA, known as polymorphisms, can be identified through DNA fingerprinting.
- The DNA fingerprinting process involves:
- Extraction and purification of the DNA from the fingerprint.
- PCR amplification to obtain high yield.
- Fragmentation of the DNA by use of restriction enzymes.
- Gel electrophoresis analysis of the fragmented DNA.
- Analysis of gel to compare the size of the bands.
