Which of the following is not true regarding the denaturation and reannealing of double-stranded DNA molecules? Which of the fol
aleksley [76]

Answer: "Decreasing the salt concentration of the solution lowers DNA's melting point (Tm)" is not a true statement

Explanation:

Increasing salt concentration would lower the DNA's melting point (Tm), not otherwise.

For instance:

- In 8M urea (8M means 8 Moles per dm3), Tm is decreased by nearly 20°C.

- 95% formamide at room temperature would completely denature the double stranded DNA.

Thus, higher concentration of salts like urea or formamide lowers Tm, not otherwise

Bacteria and archaea differ in (1 point)
Step2247 [10]
<span>Apart from their habitats, Bacteria and Archaea differ in cell wall structure and membrane lipid composition. All bacteria have peptidoglycans in the cell wall whereas the archaea do not. Both also are different in RNA polymerases and thus in their protein synthesis. </span>

Gene testing is foolproof since it scans the building blocks of humans. Please select the best answer from the choices provided.
Harrizon [31]

False

reason -

Gene testing is not full proof as there are  possibilities of discrepancies in it based on the testing procedures used and the condition of sample. Since we human beings have the same genomic structure there are chances that our DNA may match with other people who do not share a heredity with our family. Basically statistical probability is used to determine probability of paternity, relationship of any kind etc. among two individuals . usually A 99% or higher percentage of probability is considered conclusive. and thus it gene testing can not be considered as full proof

The pH scale measures the acidity of a substance. It is a negative logarithmic scale. A pH of 3 has a hydrogen ion concentration
Hitman42 [59]

Answer:

The correct answer is: a pH 2 solution has a <u>10000 times</u> greater hydrogen ion concentration than a pH 6 solution.

Explanation:

The pH scale is a measurement used to describe the acidity of a solution, and this acidity is given by the concentration of H+ (hydrogen ion) in said substance. A solution with a greater concentration of H+, is more acid than a solution with a smaller concentration of H+ and, therefore, has a lower pH. Given that the pH scale is a negative logarithmic scale, a solution with a pH of 3 has a ten times greater H+ concentration than a solution with a pH of 4.

A pH 2 solution has 10 times more H+ ion concentration than a pH 3 solution, 100 times more H+ ion concentration than a pH 4 solution, 1000 times more H+ ion concentration than a pH 5 solution, and 10000 times more H+ ion concentration than a pH 6 solution.
