While performing an experiment at home, Emma adds lemon juice to a soap solution. How will this affect the pH of the soap soluti

on?

B.) The pH will increase
C.) The pH will decrease

Vinvika [58]3 years ago
6 0
The pH scale goes from 0-14 (0-6.9 = acids and 7.1-8.0 = base and 7.0 = neutral)

Soap is a base and lemon juice is an acid.

If you add a number below 7 (an acid - lemon juice) to a number above 7 (a base - soap) then the pH will begin high and decrease.

MArishka [77]

An isolated colony on a selective medium is not considered a pure culture because inhibited organisms might be masked by the colonies. This statement is true.

On the basis of their constitution or usage, culture media can be classified into various groups; these include defined, complex, selective, as well as enrichment medium.

A selective medium consists of dyes or noxious substances/chemicals which inhibit the growth of specific microorganisms but promote the growth of other microbes.

A pure culture is a laboratory culture which contains a single species of microorganism. It is free from other microorganisms.

Since selective media affects the growth of distinct organisms differently, therefore, an isolated colony formed in such type of medium is not considered a pure culture.

Alina [70]

Answer: Option B) phosphate; hydroxyl; 3'

We identify nucleic acid strand orientation on the basis of important chemical functional groups. These are the phosphate group attached to the 5' carbon atom of the sugar portion of a nucleotide and the hydroxyl group attached to the 3'

carbon atom

Explanation:

For both RNA and DNA, chemical groups such as phosphate (PO3-) attaches to the 5' carbon of the pentose sugar (deoxyribose in DNA, ribose in RNA).

While hydroxyl group (OH) attaches to the 3' carbon atom of the pentose sugar.

Thus, a nucleic acid structure structure reveals a several repeating units of nucleotides where nitrogenous base links to a pentose sugar, who in turns is linked to phosphate group
