Explanation:
A chemical reaction bonding monomers together to make a polymer
If a cell membrane became impermeable, instead of selectively permeable, the cell would not remain alive, though certain organisms would be able to stay alive longer than others. This is because the cell membrane allows essential molecules and substances such as oxygen into the cell, while allowing harmful substances, like waste, out of the cell.

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.
