4. Maria wondered if different colors (red, orange, yellow, green, blue, and purple) of plastic wrap affected the time for bread to mold. She also wrapped a slices of bread in clear plastic wrap to see how they may normally mold. Before wrapping the same type of bread (Wonder Whole Wheat), she placed 5 ml of water in the center of each slice. The slices were of the same size and wrapped in the same manner and kept in a dark space at 75 degrees Fahrenheit. She measured the area of mold growth for one week after the mold first appeared. She observed 25 slices of bread for each color of wrap and the clear wrap as well. what is the constant variable the independant variable and the depentant variable

Constant variable: SAME TYPE OF BREAD (Wonder whole wheat), SAME AMOUNT OF WATER (5ml), SAME SIZE OF BREAD SLICE, SAME TEMPERATURE (75°F)

Independant variable: COLORS OF PLASTIC WRAP

Depentant variable: TIME FOR BREAD TO MOLD

Explanation:

In any experiment, the independent variable is the variable that is deliberately changed or manipulated by the experimenter. In this case, the independent variable is the DIFFERENT COLORS OF PLASTIC WRAP USED (red, orange, yellow, green, blue, and purple).

Dependent variable is the variable that the experimenter measures in an experiment. It is the variable that responds to changes made to the independent variable. In this experiment, the dependent variable is the TIME IT TAKES FOR BREAD TO MOLD.

Constant variable, also known as Controlled variable, is the variable that the experimenter keeps constant or unchanged for all groups throughout the experiment. In this experiment, the constants are: SAME TYPE OF BREAD (Wonder whole wheat), SAME AMOUNT OF WATER (5ml), SAME SIZE OF BREAD SLICE, SAME TEMPERATURE (75°F)

"i have always loved contemporary art and made it a general goal to work within the field. after a few nonprofit internships at museums and galleries, i decided to try the for-profit art world and was offered a job as the ad assistant at the magazine. i much prefer the pace of the for-profit art community and have stayed with the company for three years, with a promotion to an account manager last spring."

i just did this and got a 100.
