Protective custody. Protective custody is a type of imprisonment (or care) to protect a person from harm, either from outside sources or other prisoners. Many administrators believe the level of violence, or the underlying threat of violence within prisons, is a chief factor causing the need for PC units.
What are the two defining features of an experiment. for a good experiment, you need good manipulation skills (don't always ask the teacher what to do). each experiment must have a dependent, an independent and control variables. your lab report must have background info, aim, hypothesis, list of appar... view the full answer.
These changing quantities are called variables, and an experiment usually has three kinds: independent, dependent, and controlled. The independent variable is the one that is changed by the scientist. In an experiment there is only one independent variable. As the scientist changes the independent variable, he or she observes what happens. The dependent variable changes in response to the change the scientist makes to the independent variable. The new value of the dependent variable is caused by and depends on the value of the independent variable. (the independent variable), the quantity of water flowing (dependent variable) changes in response--the water flow increases. The number of dependent variables in an experiment varies, but there is often more than one.
