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.
Answer:
.The concentration of N2O4(g) and the concentration of NO2(g) must be constant.
Explanation:
N2O4(g)<--------> 2NO2(g)
At equilibrium, all the concentrations of species involved in the equilibrium expression remain constant. This is because, at equilibrium, the rate of forward reaction equals the rate of reverse reaction. The concentration of the system does not change with time. The relative concentration of each specie, remain steady at equilibrium.
Answer:
H+ ----- Br-
H+ ----- Cl-
O₋₋ -----2H++
CH3 ----- O- ------ H+
Explanation:
Dipole moment occurs when there is bonding between a very strong electronegative element and hydrogen atom.
Electronegative elements are the element which attract electrons towards themselves, (that is they have strong affinity for electrons).
Generally, group 7 elements (Fluorine, Chlorine, Bromine, Iodine) of the periodic table are highly electronegative
