Which of the following is a group that can be measured against the experimental group?
Responding.
Manipulated.
Control.
Variable.
The Correct Answer is C
A control group is a group in an experiment that does not receive the treatment or manipulation being tested and is used as a benchmark to measure how the other tested subjects do.
The control group is used to minimize the effects of all variables except the independent variable.
This allows researchers to determine if changes in the dependent variable are due to the manipulation of the independent variable or if they are due to some other factor.
Choice A. Responding is not the correct answer because it refers to the dependent variable, which is the variable that is being measured in an experiment.
Choice B. Manipulated is not the correct answer because it refers to the independent variable, which is the variable that is being manipulated in an experiment.
Choice D. Variable is not the correct answer because it refers to any factor that can change in an experiment and can include both independent and dependent variables.

Correct Answer is D
Explanation
The pleura is a double-layered serous membrane that covers each lung and lines the thoracic cage.
The pleura is a vital part of the respiratory tract.
Its role is to cushion the lung and reduce any friction that may develop between the lung, rib cage, and chest cavity.
Each pleura (there are two) consists of a two-layered membrane that covers each lung.
The layers are separated by a small amount of viscous (thick) lubricant known as pleural fluid.
The pleura is comprised of two distinct layers: the visceral pleura and the parietal pleura.
The visceral pleura is the thin, slippery membrane that covers the surface of the lungs and dips into the areas separating the different lobes of the lungs (called the hilum).
Correct Answer is C
Explanation
The data in the table shows that as the number of filters (and therefore the mass) increases, the terminal velocity also increases.
This means that the heavier objects (with more filters) are falling faster than the lighter objects (with fewer filters).
Choice A is not supported by the data in the table.
Terminal velocity is indeed when the force of gravity is equal to air resistance, but this definition does not provide any information about the relationship between mass and terminal velocity.
Choice B is also not supported by the data in the table.
The data does not provide any information about the time it takes for an object to reach terminal velocity.
Choice D is not supported by the data in the table.
The data shows that as the number of filters increases, the terminal velocity also increases.
This means that the greater the number of filters, the greater (not smaller) the terminal velocity.
