Explanation:
Denaturation. Protein denatures in certain conditions like high temperature and changes in pH
Answer:
INDEPENDENT VARIABLE: COCONUT JUICE
DEPENDENT VARIABLE: APPEARANCE OF GREEN SLIME
CONTROL GROUP: THE SIDE OF THE SHOWER HE SPRAYED WITH WATER
CONSTANT: SAME TIME OF MEASUREMENT, SAME SHOWER
Explanation:
- Independent variable is the variable that is changed or manipulated by an experimenter. In this experiment, Homer sprays a side of his shower with COCONUT JUICE and the other side with water. This means that the independent variable is the COCONUT JUICE.
- Dependent variable is the variable that responds to the independent variable. It is the variable that is measured by the experimenter. In this experiment, the dependent variable is the APPEARANCE OF GREEN SLIME on the shower.
- Control group is the group in an experiment that does not receive the experimental treatment (coconut juice). This means that the control group of this experiment is the SIDE OF THE SHOWER HE SPRAYED WITH WATER.
- Constants or controlled variable are the variables in an experiment that are kept unchanged throughout the experiment. In this case, the constant is SAME TIME OF MEASUREMENT, SAME SHOWER.
Answer:
- Determine what information is required to collect
- Determine the methodology used for data collection
- Determine the methodology used for analyzing data
Explanation:
Data collection is the process of obtaining and measuring information on a variable of interest, which is used to answer questions about a particular issue and to obtain conclusions by the evaluation of the outcomes. Data collection represents an important issue from a broad spectrum ranging from social sciences to physical/natural sciences, as well as in business structures. For example, in an international company, such data collection enables to save money by building customer's databases that help to reduce marketing efforts. Methodologies for data collection include observational procedures, interviews, questionnaires and group discussions.
