Answer:
Independent variable: Type of battery
Dependent variable: Time the clock stopped
Control: None for this experiment
Constants: Same type of clock
Explanation:
Independent variable in an experiment refers to the variable which the experimenter changes or manipulates in order to bring about a measurable response. In this case, the independent variable is the TYPE OF BATTERY USED.
Dependent variable is the variable that responds to changes made to the independent variable. It is the measured variable in an experiment. In this case, the dependent variable is the TIME THE CLOCK STOPPED FOR EACH BATTERY
Control is the group that does not receive the experimental treatment. In this case, NO control group is USED.
Constant is the variable that the experimenter keeps unchanged throughout the experiment for all groups. The constant in this experiment is the CLOCK USED.
If you suspect that a victim has closed abdominal injury, the best thing to do is to carefully position the victim on his or her back and loose any tight fitting clothing that the person may have on.
Positioning this victim like this will prevent the risk of causing further injury.

Bronchial/Tracheal cells are responsible for producing lubricating mucus to keep the airways functional and they are a type of epithelial cell, a term used generally to refer to cells lining the inside or outside of the body. These cells generate mucus and a number of other compounds, which play an important role in respiration.
