Independent variable: Temperature
Levels: Room temperature
Freezing point 0C
Boiling point 100C
Dependent variable: breaking point of rubber bands measured in certain amount of temperature
When a scientific experiment is carried out in a controlled setting, all variables are kept the same except for the C. experimental. Experimental variables are the things you are studying in the experiment and it is the only variable you can change.
Answer:
Elements that are metals tend to lose electrons and become positively charged ions called cations. Elements that are nonmetals tend to gain electrons and become negatively charged ions called anions

Vibrissae, more commonly known as whiskers, are sensory hair
that generally have a tactile sense, which is equivalent to skin. They grow on
most mammals except monotremes (duck-billed platypus and echidnas) and humans,
though humans still have remnants of the muscles once associated with vibrissae
in their upper lips. Vibrissae serve a number of purposes: such as sense of
touch; detection of danger, air and water currents, and movements of other
animals; and the locating of food.
