Answer:
Alec Jeffreys and the Pitchfork murder case: the origins of DNA profiling
British geneticist Alec Jeffreys began working in 1977 on a technique that could identify individuals through samples of their DNA. In 1984, he and colleagues devised a way to use a newly discovered property of DNA, isolated areas of great variability between individuals called restriction fragment length polymorphisms (RFLP), for forensic identification—the original DNA fingerprint.
In 1986, police asked Jeffreys for help in finding a man who had raped and killed two girls. DNA tests exonerated the primary suspect. Through a genetic dragnet, police found the perpetrator, Colin Pitchfork, who gave himself away when he asked a friend for a substitute blood sample.
Within a year, genetic fingerprinting was making the unique molecular structures of victims and suspects visible in criminal investigations around the world. Today, RFLP-based DNA analysis is being supplanted by newer techniques of genetic identification.

Answer:
I don't know correct answer but I think it is <em>night time</em> in b point.
Answer:
During chemosynthesis, bacteria living on the sea floor or within animals use energy stored in the chemical bonds of hydrogen sulfide and methane to make glucose from water and carbon dioxide (dissolved in sea water). Pure sulfur and sulfur compounds are produced as by-products.
Explanation:
Tendons are similar to ligaments and fasciae as they are all made of collagen, but a ligament joins one bone to another and fasciae connect muscles to other muscles.
Leaving, A as the correct answer among all the other answers above stated.
Answer:
why is reproduction considered as a life function?
Reproduction is considered as life function because it enable life continuity as a result of the new generation brought to life. Inheritable characteristics are being passed from one generation to another as a result of reproduction.
Explanation:
Without reproduction, there would not be life continuity, life would have end without it as no character would have been inheritable
