Explain whether nuclear or mitochondrial DNA is better for identifying a specific person
hodyreva [135]

Answer:-

Nuclear DNA is inherited from all ancestors. But mitochondrial DNA is inherited from a single lineage. The DNA inside of mitochondria (called mtDNA) unlike DNA inside the nucleus, comes from only mothers.

It is not a mixture of our parent’s DNA, and each person’s mtDNA is nearly identical to his or her mother’s mtDNA.

Thus only nDNA being more unique is more useful for identifying in forensics. In cases where nDNA is not sufficient, mtDNA is used.

The pressure on 150 mL of a gas is increased from 500 mm Hg to 700 mm Hg at constant temperature. What is the new volume of the
Ivanshal [37]

Answer:

Option A. 107 mL

Explanation:

From the question given above, the following data were obtained:

Initial volume (V₁) = 150 mL

Initial pressure (P₁) = 500 mmHg

Final pressure (P₂) = 700 mmHg

Temperature = constant

Final volume (V₂) =?

The final volume of the gas can be obtained by using the Boyle's law equation as shown below:

P₁V₁ = P₂V₂

500 × 150 = 700 × V₂

75000 = 700 × V₂

Divide both side by 700

V₂ = 75000 / 700

V₂ = 107 mL

Therefore, the final volume of the gas is 107 mL.
