Answer:
As the variables are not given, let us help with general explanation on manipulated variable.
Explanation:
A manipulated variable is an independent variable. In a scientific experiment, an independent variable can be described as a variable which can change naturally or which is changed by the researcher to check its effect on the dependent variable. The dependent variable is the variable which is under study and being tested.
For example, to check the difference in photosynthesis rate by light, the amount of light will be the independent variable and the rate of photosynthesis will be the dependent variable.
Tomatoes are commonly grown from seedlings started indoors that are later transplanted into the garden. Tomato seeds are commonly planted indoors as early as 8 to 6 weeks before the average date of the last spring frost. Tomato seedlings are usually transplanted into the garden 1 to 3 weeks after the last frost. Wash tomatoes under cool running water.
Slice an "X" on the bottom of each tomato with a small utility knife. In a large saucepan bring water to a rolling boil. Fill a large mixing bowl with ice cold water. With a large spoon, place tomatoes in boiling water for 30 seconds to loosen skin. Remove tomatoes after 30 seconds, place directly into cold water to stop the cooking process. Core the tomatoes by removing the stem with a paring knife. Peel away the skin, being careful not to injure the flesh of the tomatoes.
