Answer:
Below .
I hope the information give below is helpful .
Explanation:
In question 1 ;
The independent variable is the fertilizer
The dependent variable should be the rate of growth of the plants
The constant doesn't change so other factors that affect plant growth and health, such as soil quality and watering, would need to remain constant.
The controlled variables might be things such as the the quality of soil and the amount of water given to the plants. If these factors were not constant, and certain plants received more water or better soil than others
The experiment in question 1 is a controlled experiment
The part of the garden that didn't receive fertilizer is the control group
According to the question; She didn't hypothesize .
In question 2 '
The independent variable is the floor wax
The dependent variable was protecting the floor tiles against scratches.
It is a controlled experiment but there's no much information to determine if there is any variability and repetition )
The sections that received no wax is the control group
There is no hypothization (if that's a word :) ).The shopping mall didn't hypothesize (maybe that the tough steel would be better )
I'm not sure of any constant needed when applying floor wax.
