Answer:
Different liquid
Explanation:
<em>The independent variable in the investigation is the different liquid given to the plants.</em>
<u>The independent variable in an experimental investigation is the variable that is supplied by the researcher which directly affects the main variable being measured during the investigation. In other words, the independent variable is a variable that directly affects the dependent variable.</u>
In this case, the dependent variable would be growth determining factors in plants such as height, biomass, number of leaves, etc. while the independent variable would be the different types of liquid given to the plants.
The orange pigment carotene absorbs the orange wavelength of light very poorly, which makes the leaves appear orange.
The compounds that can be formed by using only the cations and anions found in the item above are as follows: (1) Ca3(CO2)2, Na3CO2, NaOH, Ca(OH)2
The last two in the given are in aqueous phase. We are then left with the first two choices. Ca3(CO2)2 is exhibits a phase that is in solid form.
Hence, the answer to the question is Ca3(CO2)2
