Hello I know the answer to your question the answer is true
Answer:
Explanation:
Species can have multiple adaptations such as either structural or reproductive adaptation.
Example of structure adaptation for animals would be for giraffe. Their long neck allow them to reach for food high up in the trees. They have adapted to their environment.
Example of reproductive adaptation would be for flowers. The reasons plants have bright colored flowers is so that they can attract insects, birds or even bats which can inadvertently transfer pollen from one plant to another.
Redbeds indicate the presence o iron in the environment. Red beds are red sedimentary rocks and the color is due to the presence of the ferric oxides. Ferric oxides occur as a coating on the sedimentary grains. In between the shale and cherts, iron-rich sediments can be found.
Answer:
The correct answer is -
the independent variable - if fertilizer added or not,
the dependant variable - the height of the plant and
the standardized variable - 200ml water
Explanation:
In this study, the student wanted to see the effect of the fertilizer on the growth of the plant so the independent variable is the treatment of the fertilizer as manipulated or the independent variable is the factor which is affected or changed purposely during an experiment while other variables remain constant.
The dependent variable is the factor that is based or depends on the independent variable and measured to see the effect which is the height of the plants in this case.
The standardized or the control variable is the variable that remains constant throughout the experiment, 200 ml water treatment is the control variable in this experiment.
