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.
No, producers produce their own food like plants that use photosynthesis to produce sugar whilst aphids cannot produce their own food and have to feed of other plants.
To determine whether a cell is a eukaryotic or
prokaryotic cell, one can observe certain features.
If the cell in the question possesses a well-defined
or definite nucleus and have membrane-bound
organelles such as mitochondria, chloroplasts,
Golgi apparatus, endoplasmic reticulum, the cell is
eukaryotic. If the cell has nucleoid or indefinite
nucleus and without membrane-bound cell
organelles, the cell is prokaryotic. If ribosomes in
a cell are the 80S (S=Svedberg units) type, the cell
is eukaryotic and if ribosomes are 70S type then it
is prokaryotic.
