Answer:

high less & low more

Explanation:

pH measures the quantity of hydrogen ions in a solution of a given volume, if pH is a low number, the amount of hydrogen atoms will increase, and if the pH is high, the amount of hydrogen atoms will decrease. So both high & less, and low & more are correct answers.

Answer:

When a substance has a high less pH, it has low more hydrogen ions for a given volume.

Explanation:

The pH, or Hydrogen Potential, is the scale that measures the degree of acidity or alkalinity of a substance, which can vary from 0 to 14.

PH is a characteristic of all substances, determined by the concentration of Hydrogen ions (H +). The lower the pH of a substance, the higher the concentration of H + ions and the lower the concentration of OH- ions. For this reason, we can affirm that when a substance has a high less pH, it has low more hydrogen ions for a given volume.

Knowing the pH of substances is a process that requires the help of a pH meter. Through this device it is possible to accurately measure the acidity of liquids.

irga5000 [103]

Answer:

The correct option is C. A virus contains RNA or DNA in a protein coat.

Explanation:

Viruses can be described as tiny particles which are able to incorporate their genetic material into a host. Many viruses can be destructive to the host cells.

The structure of a virus includes DNA or RNA which is enclosed in a structure known as an envelope or capsid. The envelope or capsid is made up of proteins. Some viruses also have a tail.

The capsid of a virus usually remains outside the host cell and it injects its viral genome into the host cell. The DNA or RNA o the virus then incorporates in the host cell.

Why does ethanol becomes cloudy/white when testing fat
ki77a [65]

Answer:

Ethanol is known as a fat solvent, and the cloudy or white color that it acquires when testing fat is due to the fact that this test includes the addition of water, forming an emulsion.

Explanation:

<u>The emulsion test for fats</u> is a test used to show the presence of these in some substances or foods.

Under normal conditions, fats are miscible - they can be dissolved - in ethanol, an alcohol, but not in water.

This test consists of dissolving the substance to be tested in ethanol, and then adding water. The principle by which the emulsion test is governed is that ethanol allows a certain amount of fat to dissolve in water, forming a cloudy or whitish emulsion.
