Answer:
The correct answer is :
Independent variable: study music.
Dependent variable: test performance.
Explanation:
Independent variable in a experiment is a variable or a factor that is manipulated or changed in a particular experiment to see its the effect on dependent variable of this change. In this case classical music is variable as it is manipulated to see if it has any effect on studying.
Dependent variable is a variable which is measured in experiment to find the result and affected by the independent variable. In this case testing the performance of subject is dependent variable as it is being measured and affected by classical music.
Thus, the correct answer is: Independent variable: study music.
Dependent variable: test performance.
Answer:
Estrogen.
Explanation:
Plasma membrane is made of lipids and proteins. The lipids are arranged in bilayers and proteins are embedded or may span the lipid bilayer. The carbohydrates are attached on the surface of the membrane.
The molecules that are lipophillic in nature can easily diffuse through the plasma membrane. Among the molecules listed in the question, estrogen is highly lipophillic in nature and can easily cross the lipid bilayer of the plasma membrane.
Thus, the correct answer is option (d).
Answer:
Pentanol, glucose and fatty acid.
Explanation:
Pentanol, glucose and fatty acid are the three molecules which are present in the given model number 1. In the model, there are three different molecular diagrams for each molecule. The first one is ball and stick model, the second one is Lewis structure and the third one is line drawing method. All diagrams for a same molecule is totally different from another.
