Manipulation of the independent variable should change the dependent variable, the value of which "depends" on the independent variable's change in value.
The given above pretty much states already that with the presence of the calcium carbonate which acts as the buffer will allow the solution to withstand changes in acidity. The greater the amount, the higher chances that it will be able to withstand the said changes. Therefore, if Lake X had greater ppm of CaCO3 then, it will be able to withstand greater amount of acid rain.
When the atmospheric pressure is equal to the vapor pressure of the liquid, boiling of liquid will begin.
<h3>What happens when atmospheric pressure is equal to the vapor pressure of liquid?</h3>
When the atmospheric pressure is equal to the vapor pressure of the liquid, boiling will begin. The bubbles formation started to the liquid molecules which have gained enough energy to change to the gaseous phase.
The vapor pressure of ethanol is 5.95 kPa at 20.0 °C, and its vapor pressure is 53.3 kPa at 63.5 °C.

Answer:
The correct answer is B. exogenous
Explanation:
Let us try to describe exogenous and endogenous variables an exogenous variable value is influenced only by factors outside a model or system and is forced onto the model, while a change in an exogenous variable is known as an exogenous change. Also an endogenous variable is one whose value is influenced only by the system or model under study.
