Manipulated variable is also known as the independent variable. The independent variable may determine if a seed germinates. Examples of manipulated variables for seed germination include: water, suitable temperature and air/oxygen. These basic variables are also the most important in seed germination.
Germination in a seed typically begins when the seed is planted in soil and provided with the right conditions such as water, warmth, and oxygen.
Oxygen gas is needed by the seed during germination. Aerobic respiration takes place during seed germination to release lots of energy required for this process.
A manipulated variable is also called an independent variable. It is the thing in an experiment you change or manipulate. For example, if i am doing an experiment to see how water affects the growth on plants, the amount of water is the manipulated variable.
Germination of a seed is generally considered an irreversible process, as it marks the beginning of the growth of a new plant. Once the seed has undergone germination and starts to grow, it cannot revert back to its dormant state.
The biome with the longest seed germination time is typically the arctic tundra due to the cold temperatures and short growing season that restricts seed germination and growth. Some seeds in the arctic tundra can remain in the soil for years before conditions are right for germination.
There is no answer to a manipulated variable because "a manipulated variable" is not a question!
the result
It can be. If you are looking at the germination time under different conditions of temperature and humidity etc.
operational definition of a manipulated variable
The manipulated independent variable is the variable that the researcher intentionally changes or controls in an experiment to observe its effect on the dependent variable. This variable is manipulated by the researcher to determine the impact it has on the outcome of the study.
The dependent variable may change in response to the manipulated variable.

It means that a variable is manipulated!(:
In an experiment, the manipulated variable is also known as the independent variable. An example of the term "manipulated variable" in a sentence would be, "The scientist sincerely hoped that the manipulated variable would produce a reaction in the dependent variable."
Germination.
No, a manipulated variable (also known as independent variable) is deliberately changed in an experiment to see its effect on the dependent variable. The dependent variable is what is being measured or observed in response to changes in the manipulated variable. They are not the same but are related in an experiment.
A manipulated variable is not changed on purpose.
