Lupe is conducting an experiment to find out what type of antibacterial soap kills the most bacteria. in her experiment, lupe grows e. coli bacteria in ten different petri dishes. lupe then sprays 10 milliliters of an antibacterial soap on nine of the petri dishes. each of the nine petri dishes is sprayed with a different brand of soap. lupe doesn't spray any soap on the tenth petri dish. in lupe's experiment, what is the independent variable? a. the brand of antibacterial soap b. the type of bacteria grown c. the tenth petri dish

The correct answer is "The brand of antibacterial soap "

Explanation:

An independent variable in an experiment is the variable that is changed by the scientist. Independent variables are also known as manipulated variables.

In Lupe's experiment, the independent variable is the brand of soap.

In controlled scientific experiments, only one variable should be changed at a time (i.e., there should only be one independent variable per experiment). If only one variable is changed, then it is possible to clearly relate experimental results to a particular variable.

homeostasis is the tendency towards a relatively stable equilibrium between interdependent elements, especially as maintained by physiological processes. and this is how it applies to the integumentary system. back to top. skin functions in homeostasis include protection, regulation of body temperature, sensory reception, water balance, synthesis of vitamins and hormones, and absorption of materials. when body temperature falls, the sweat glands constrict and sweat production decreases.
