emmasim [6.3K]

Answer:

The correct answer is the last option, that is, multigene families are similar or identical genes, whose evolution took place by gene duplication.

Explanation:

A member of a family of the associated proteins encrypted by an array of identical genes is known as a multigene family. It is considered that the origination of the multigene families has resulted due to the variation and duplication of a single ancestral gene.  

The multigene families make the assembly of the proteins comparatively quickly, as it assists in the simultaneous transcription of various genes at distinct locations.

Ph, Acids and Bases Quick Check
RoseWind [281]

The statement that best describes the difference is ; The substance with the lower pH has 1000 times as many hydrogen ions per volume of water. ( D )

Given that the substance have pH ; 3 and 6

To prove the statement above we will make use of the pH formula

pH =  -log(H⁺)

<u>for substance with </u><u>pH = 3</u><u> </u>

3 = - log(H⁺)

H⁺ ( hydrogen ions ) = 10⁻³

<u>for substance with </u><u>pH = 6</u>

6 = - log(H⁺)

H⁺ ( hydrogen ions ) = 10⁻⁶

Hence we can state that the substance with the lower pH has 1000 times as many hydrogen ions per volume of water
