Q1. The answer is b) studying chemicals containing carbon.
Pure chemistry, as its name suggests, is the study of pure, basic theory of chemistry, and has no applied aspect. On the other hand, there is applied chemistry with research for some intended purpose and application. Now let's take a look at the choices: effects of drugs on human (purpose is understanding drug effects), a cure for osteoporosis (applied aspect), an antidote for a new strain of virus (applied aspect) are examples of applied chemistry because they have some purpose. On the other hand, studying chemicals containing carbon has no applied aspect, it is a study because of pure knowledge.
Q2. The answer is d) structure of a muscle cell.
Among choices, only the structure of a muscle cell is not visible to human eyes. Imagine foam insulation, X-ray of a knee joint, a shape of a plant - all of these are visible to human eyes. However, if you want to see a structure of a muscle cell, you will need a microscope. The microscopes are able to magnify specimens and are used to see structures that you cannot see with naked eye.

Q3. The answer is d) responding.
An independent (manipulated) variable is variable that is not affected during the experiment. It is what experimenter controls. A responding variable is also called a dependent variable. The dependent (responding) variable is called dependent because it depends (it responds) on the independent variables. It is what is affected and what is observed during the experiment.
1. B) Studying chemicals containing carbon
2. D) structure of a muscle cell
3. D) Responding
FURTHER EXPLANATION
QUESTION 1
Pure chemistry is studying chemistry for the sake of knowledge and for the sake of knowing. It is not focused on finding or testing any possible applications or uses for the knowledge or learning. Applied chemistry, on the other hand, involves studying how information about matter may be used for something beneficial.
A. Testing the effects of lower concentrations of a drug on humans
APPLIED CHEMISTRY: focus is on the application of chemicals (drugs) on humans
B. Studying chemicals containing carbon
PURE CHEMISTRY: goal is only to learn about the chemicals with carbon; there is no implied agenda of using what is learned for something else
C. Developing a cure for osteoporosis
APPLIED CHEMISTRY: goal is to find an application or use of chemicals (medicine) for the benefit of patients with osteoporosis
D. Finding an antidote for a new strain of virus
APPLIED CHEMISTRY: focus is on applying knowledge about chemicals to find a cure or antidote
Question 2
Microscopes are used to view very tiny things or organisms that are invisible to the naked eye.
A. Foam insulation – can be viewed by the naked eye
B. X-ray of a knee joint – can be viewed by the naked eye
C. Shape of a soybean plant – can be viewed by the naked eye
D. Structure of a muscle cell – too small to be seen by the naked eye and requires use of a microscope for enhanced magnification.
Question 3
A. Independent variable is the variable that is purposely changed during the investigation.
B. Manipulate variable is another term for independent variable.
C. Controlled variables are the variables that are held at constant values or variables that remain the same in every trial or experiment. This is done to ensure that the cause of the any changes in the observations are only due to the manipulated or independent variable.
D. Responding variable or dependent variable is what is observed or measured during an experiment. This the effect of the manipulations or changes done to the independent variable.
