Solution A has 10 times more hydrogen ions than solution B.. The correct option is B.
<h3>What is a pH?</h3>
pH is the potential of hydrogen ions, or measure of hydrogen ion concentration.
It is generally used to determine the acidity and basicity of the solution based on pH scale.
The pH scale is logarithmic, which means that each pH unit contains ten times the number of hydrogen ions as the unit above it. So solution A has 10 times more hydrogen ions than solution B.
Thus, the correct option is B.

Answer:
C. Organisms are now divided into three kingdoms.
Explanation:
In the early 1860s, a German scientist named Ernst Haeckel suggested using a three kingdom system of classification. Haeckel's three kingdoms were Animalia, Plantae, and Protista.
Answer:
Stomata opens to intake carbon dioxide in the presence of light there by allowing the process of photosynthesis during the day time.
Explanation:
The gaurd cell of the stomata play an important role in regulating the photosynthesis. During the day time, the stomata is open which allows intake of carbon dioxide from atmosphere. Carbon dioxide is very essential for the process of photosynthesis. Thus, during day time when stomata is open photosynthesis takes place while during night time when stomata is closed photosynthesis do not occur. Also the stomata regulate the loss of water from the leaves thereby ensuring availability of sufficient water molecules at the time of photosynthesis.
In biotechnology, the process of introducing the foreing DNA into a cell by a virus is called transduction.Gene therapy is one of the purposes of this process.
