Independent variable: FERTILIZER.
This is the variable that you think affect your dependent variable and so you change it and use different types of it to confirm your prediction.
Dependent variable: COLOR.
That is the variable you are interested in.
Hypothesis: THE TYPE OF FERTILIZER USED IN CULTIVATING HYDRANGEA FLOWER AFFECT THEIR COLOR.
An hypothesis is a generalized statement which predicts the relationship between the variables you are examining.
Control group: THE GROUP THAT DID NOT GET ANY FERTILIZER
The control group is the group that does not receive any treatment.
Experimental groups: THE GROUPS THAT RECEIVED FERTILIZERS.
The experimental group is the group that receives treatment.
Constants: TYPES OF SOIL USED, MORNING SUNLIGHT, WATER AND THE NO OF DAY THE EXPERIMENT LAST.
The constants are the inputs into your experiment which you give to all the groups.
Answer:
a series of pools built like steps to enable fish to bypass a dam or waterfall.
Explanation:
A fish ladder, also known as a fishway, fish pass or fish steps, is a structure on or around artificial and natural barriers to facilitate diadromous fishes' natural migration.
Answer:
Yes, there would be no sugars present in any of the solutions as no colour change was depicted.
Explanation:
Benedict's solutions can be described as a solution comprising of copper(II) sulphate, sodium carbonate and sodium citrate. This reagent is used for testing the presence of carbohydrates or reducing sugars in a solution.
A series of colour changes is seen in the Benedict's test if a solution has sugars present in it. Initially, the colour is changed from blue to green, then orange/yellow. And in the end, the solution acquires a brick red colour.
In the scenario discussed in the question, no colour change is depicted in any of the test tubes. Hence, there would be no sugar present any of the solutions.
