According to the concept of solubility, carbonic acid is a mixture of water and carbon dioxide.
Solubility is defined as the ability of a substance which is basically solute to form a solution with another substance. There is an extent to which a substance is soluble in a particular solvent. This is generally measured as the concentration of a solute present in a saturated solution.
The solubility mainly depends on the composition of solute and solvent ,its pH and presence of other dissolved substance. It is also dependent on temperature and pressure which is maintained.Concept of solubility is not valid for chemical reactions which are irreversible. The dependency of solubility on various factors is due to interactions between the particles, molecule or ions.
A mixture of water and carbon dioxide under high temperature and pressure forms carbonic acid as it is highly soluble,thus carbonic acid is a mixture of water and carbon dioxide.

Which is one characteristic that temperate marine and temperate continental climates have in common?
mild winters
hot summers
many tall trees
moderate amounts of precipitation
Answer: D : moderate amounts of precipitation
Explanation:
The one characteristic that temperate marine and temperate continental climates have in common is moderate amounts of precipitation. Thus, the correct option for this question is D.
What is Climate?Climate may be characterized as the long-term pattern of weather in a particular area. It is different from the weather in a way that can change from hour to hour, day-to-day, month-to-month, or even year-to-year.
According to the context of this question, A maritime climate is influenced by a nearby ocean. A continental climate is influenced by nearby land. The temperature of offshore currents affects nearby land areas.
A maritime climate is less extreme than a continental climate because the ocean moderates temperatures. Due to this, both temperate marine and temperate continental climates have moderate amounts of precipitation.
Therefore, the correct option for this question is D.

Think of the Responding Variable as the result of the variable only can change when Manipulated is changed. (This is the Dependent Variable)
Hope This Helps :)
Manipulated variable in each case are watering of plants, number of chocolates, trees having leaves,water in acid rain, amount of calcium respectively and responding variables are growth height, amount of homework,number of bird nests,fish population,bone strength.
What are variables?Variables are defined as any characteristics, number or quantity which can be measured . It can also be called as a data item . It is called as variable because they can vary and can have variety of values.
There are three types of variables 1) manipulated variable where in a condition is specified, 2) responding variable which is dependent on manipulated variable 3)controlled variable which do not change
Example of manipulated variables are number of hours spent by a student studying , that of responding variable is result of a student and temperature is an example of controlled variable.
