Answer:
Independent Variable - Soil, Dependent Variable - Height, Control Variable - Sun and Water
Explanation:
First we should define what the variables in the experiment are.
Independent variable is the aspect of the experiment that has a different value for each subject in order to find out how it affects the dependent variables.
Dependent variable is the variable that is kept under observation and recorded by the experimenters in order to track the changes and define its relationship with the other variables/parameters.
Control variable is the variable that is kept constant intentionally by the experimenters to be able to define the relationship between the other variables more clearly and easily.
In the example given in the question, there are one of each variable mentioned above which are, according to the definitions;
- Independent Variable - The Soil
- Dependent Variable - The Height Of The Plant
- Control Variable - The Amount of Water and Sun Exposure
I hope this answer helps.
3. Decreased variation in the shades of red because no form of the trait is advantageous.
Fruit growing have following economic and
nutritional advantages. High productivity: High
yield per unit area: From a unit area of land more
yield is realized from fruit crops than any of the
agronomic crops. The average yields of Papaya,
Banana and Grapes are 10 to 15 times more that of agronomic crops.
Topoisomerase is the enzyme that can be added to correct the untwisting that is led to strain ahead of the replication fork.
