Answer:

mtDNA is used when other forms of DNA analysis are not possible because it does not rely on nuclear DNA.

mtDNA may also be useful in missing-person cases.

PCR analysis allows a small amount of DNA to be duplicated into a testing amount.

Y chromosome analysis examines genetic markers that are passed from father to son.

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.

Hydrogen reacts with chlorine to form hydrogen chloride (HCl (g), mc012-1.jpgHf = –92.3 kJ/mol) according to the reaction below.
Kobotan [32]

<u>Given:</u>

H2(g) + Cl2 (g) → 2HCl (g)

<u>To determine:</u>

The enthalpy of the reaction and whether it is endo or exothermic

<u>Explanation:</u>

Enthalpy of a reaction is given by the difference between the enthalpy of formation of reactants and products

ΔH = ∑nHf (products) - ∑nHf (reactants)

      = [2Hf(HCl)] - [Hf(H2) + Hf(Cl2)] = 2 (-92.3) kJ = - 184.6 kJ

Since the reaction enthalpy is negative, the reaction is exothermic

<u>Ans:</u> The enthalpy of reaction is -184. kJ and the reaction is exothermic

What factors do not affect nuclear reactions, but do affect chemical reaction
Fudgin [204]
Unlike nuclear reactions, nuclear reactions are not affected by changes in temperature,
pressure, of the presence of catalysts. Also nuclear reactions of given radioisotope cannot be slowed down, speeded up, or stopped.

You have a red ballooe that has a volume of 20 liters, a pressure of 1.5 atmospheres and a temperature of 28 C. What is the volu
ki77a [65]

Explanation:

The given data is as follows.

 P_{1} = 1.5 atm,     V_{1} = 20 L,  T_{1} = (28 + 273) K = 301 K

   P_{2} = 5 atm,     V_{2} = ?,  T_{2} = (50 + 273) K = 323 K

Formula to calculate the volume will be as follows.

         \frac{P_{1} \times V_{1}}{T_{1}} = \frac{P_{2} \times V_{2}}{T_{2}}

Putting the given values into the above formula as follows.

        \frac{P_{1} \times V_{1}}{T_{1}} = \frac{P_{2} \times V_{2}}{T_{2}}  

        \frac{1.5 atm \times 20 L}{301 K} = \frac{5 atm \times V_{2}}{323 K}  

                 V_{2} = 0.64 L

Thus, we can conclude that the change in volume of the balloon will be 0.64 L.

What causes the biggest change mass or speed?
Norma-Jean [14]

Answer:

Explanation if an object is in motion and more force is applied to it, the object will begin moving faster. If two objects have the same mass and a greater force is applied to one of the objects, the object which receives the greater force will change speeds more quickly.:
