zepelin [54]

Answer:

This question is asking to identify the following variables:

Independent variable (IV): TYPE OF SOIL

Dependent variable (DV): HEIGHT AND NUMBER OF LEAVES

Control group: None in this experiment

Constant: SAME ROSE PLANT, SAME TIME INTERVAL (1 WEEK)

Explanation:

Independent variable in an experiment is the variable that is manipulated or changed by the experimenter in order to effect a measurable outcome. In this case, the independent variable is the TYPE OF SOIL used.

Dependent variable is the measurable variable that responds to changes made to the independent variable. In this experiment, the dependent variable is the HEIGHT AND NUMBER OF LEAVES of each rose.

Constants or control variable is the variable that is kept unchanged or constant for all groups throughout the experiment. In this experiment, the constants are SAME ROSE PLANT, SAME TIME INTERVAL (1 WEEK).

Control group are the groups that does not receive the experimental treatment. In this case, all the groups received the experimental treatment (different soil types). Hence, there is no control

PLEASE HELP HONESTLY!!! 50 POINTS TO THE BRAINIEST!!! :)
krek1111 [17]
Im not gonna write for you a whole short story (I don't have time), but just describe what you observed (in a fake reality).

For the relationship between the predator-prey: you could say a snake eating a mouse. 

Commenalism: lets say...moss grows on a tree and benefits, but it doesn't hurt or effect the tree.

Mutalism: a bird on a rhino. The bird eats parasites and bugs that feed off the rhino, the bird gets food and the rhino stays clean and parasite free.

Parasitism: a dog and a flea. Only the flea benefits from the dog. The dog has to suffer from the parasites evilness. 

Now just thread it together and describe it. Comparing is easy, just use the definition of, for example, commensalism, mutalism, in one relationship, one organism benefits, in the other, both benefit.
Have fun!
