The independent variable likely influenced the rate of fermentation by altering key factors such as temperature, pH, or substrate concentration, which can impact the activity of the yeast or other organisms involved in the process. A change in the independent variable would lead to changes in these factors, thereby either promoting or inhibiting fermentation and affecting the rate at which it occurs.

In an experiment to determine the effect of different brands of fertilizer on the rate of plant growth what are the independent and dependent variables?
The independent variable in this experiment is the different brands of fertilizer being tested. The dependent variable is the rate of plant growth, which will be measured and influenced by the independent variable.
What is the dependent the independent variable and control for the candle experiment?
Independent variable: the type of candle used (e.g. beeswax, paraffin). Dependent variable: the rate of burning, duration of flame, or amount of wax melted. Control: factors kept constant across all candle trials, such as the room temperature, size of wick, and initial length of the candle.
What is the independent variable in the magnesium oxide reaction?
The independent variable in the magnesium oxide reaction could be the amount of magnesium used or the temperature at which the reaction takes place. These factors can be manipulated or controlled to observe their effect on the outcome of the reaction.
What is the depented variable of a lava lamp?
The dependent variable of a lava lamp experiment could be the rate of movement of the wax blobs in the lamp, the time it takes for the wax to melt completely, or the temperature of the liquid inside the lamp.
Does room temperature affect how much gas is created by yeast?
Yes. as temperature rises pressure rises and density rises.
Independent variable in measuring heart rate?
Time is the independent variable.
Dummy variable as an independent variable?
An independent variable is the variable you have control over, what you can choose and manipulate. It is usually what you think will affect the dependent variable. In some cases, you may not be able to manipulate the independent variable. It may be something that is already there and is fixed, something you would like to evaluate with respect to how it affects something else, the dependent variable like color, kind, time. Example: You are interested in how stress affects heart rate in humans. Your independent variable would be the stress and the dependent variable would be the heart rate. You can directly manipulate stress levels in your human subjects and measure how those stress levels change heart rate.
Identify the dependent and independent variable in this sentence Does the tempo of the music affect the human pulse rate?
dependent- human pulse rate independant- tempo of music
How would you write a dependent and independent variable for growth of crystals in a faster rate depending on temperature?
Dependent variable: growth of crystals Independent variable: temperature.
When measuring the breathing rate of fish over time the variable is independent or dependent?
independent
In an experiment to determine the effect of different brands of fertilizer on the rate of plant growth what are the independent and dependent variables?
The independent variable in this experiment is the different brands of fertilizer being tested. The dependent variable is the rate of plant growth, which will be measured and influenced by the independent variable.
What is the difference between dependent asnd independent variables?
The independent variable is the one that the person doing the experiment changes themself. The dependant variable is the one that is recorded as results. For example, if investigating the effect of water on the rate of photosynthesis, you would change the amount of water and record how the rate of photosynthesis changes. Therefore, the amount of water is the independent variable and the rate of photosynthesis is the dependant variable.
What is the ratio that compares the amount of chage in a dependent variable to the amount of change in an independent variable?
Rate of Change
What is a ratio that compares the amount of change in the dependent variable to the amount of change in the independent variable?
rate of change. :)
What is a ratio that compares the amount of change in a dependent variable to the amount of change in an independent variable?
rate of change. :)
What is the physical significance of gradient define?
The gradient of a curve is the rate of change in the dependent variable relative to the independent variable.
What is the independent variable in a rate of growth of a plant exposed to sunlight and one that is not?
Whether or not the plant is exposed to sunlight. Independent variables are manipulated by the experimentor, dependent variables react to the change in the independent variable.
