Answer/Explanation:
STR analysis
Short tandem repeats (STRs) are the genetic information present in the FBI's database. These are repetitive regions of the genome, and used for DNA profiling in a variety of applications. They can be used to discriminate between non-related individuals, as people have different numbers of repeating units. A combination of approximately 13 regions are analysed, giving a unique genetic fingerprint
mtDNA analysis
mt DNA is mitochondrial DNA. This type of analysis can trace the maternal lineage of a person, as mitochondrial DNA is inherited from the mother, and is largely unchanged throughout a maternal line. This is often useful when DNA is too degraded to obtain accurate STRs, as there are many more copies of mtDNA in the cell than nuclear DNA. It is also useful for linking missing relatives.
formed from the electrostatic attraction between oppositely charged ions in a chemical compound.
Metals contain free electrons
Rubber has bound electrons
The time taken to the nearest tenth of a minute, would it take the element to decay to 98 grams is 9.897.
<h3>What is half-life?</h3>
Half-life is the time half-time of the total decay of any element.
Given that, Initial amount = 970 grams
Final amount = 98 grams
Half life = 13 minutes
To find the half life
Thus, the time taken to the nearest tenth of a minute, would it take the element to decay to 98 grams is 9.897.
