Answer:
The correct answer is :
Independent Variable: side of the shower with lemon juice
Dependent Variable: cleanliness of shower
Control: spray of water
Conclusion: lemonade juice have no effect on slime
Explanation:
Independent variable in any experiment is the variable that is changed or manipulated as here side of the shower that is sprayed with lemonade juice is manipulated to see if there is any effect on the cleanliness of shower.
Dependent variable is the variable that is observed or measured to check if manipulated variable or independent variable have any effect on it, like the cleanliness is measured to check if lemonade juice clean the slime of the side or not.
The control is something that remains the same to check the condition or effect that is not changed or can be compared to it. Water spray is control in this case.
The conclusion of this experiment is that there is no effect of lemonade juice on the cleanliness of slime present in the shower

- There are around seventy meteorites recognised to have come from the planet Mars till up to the present date.
- There are three types of meteorites such as Martian meteorites and a sample of two lunar meteorites.
- To identify the origin of the meteorite, the scientist tries to identify the type of rock followed by analysing the chemical composition and then try to identify its age.
