I'm not sure what you mean by "the presence of a solution." If the metal is simple dissolved in water (in the form of a metal salt for instance), than no, the flame test will still work fine. If you mean that there are other things present in the solution, then each element will still make the same color in the flame, but because the mixture of elements will provide a mixture of colors, it will be quite difficult to determine what is present in the mix (especially because of the way colors can combine to give new colors).
To detect a cause-and-effect relationship between a blue sky and a blue ocean, you could conduct an experiment where you vary the brightness or color of the sky artificially and observe how it affects the color of the ocean. This would involve controlling the lighting conditions or using color filters to simulate different sky colors and noting any corresponding changes in the ocean's appearance.
Yes, Benedict's solution needs heating to test for glucose. Heating helps to facilitate the reaction between glucose and the copper ions in the Benedict's solution, resulting in a color change that indicates the presence of glucose.
The universe as a whole does not have a specific colour. However, in a science experiment, when an antacid solution is added to a universal indicator, it may change colour based on the pH level of the solution. This change in colour signifies the acidity or alkalinity of the solution.
it means what color it turns after or before the experiment
The color of the paper changes based on the acidity or alkalinity of the solution it is dipped in. By comparing the color of the paper to a pH color chart, the pH of the solution can be determined.

the color of the leaf become brown-black after the iodine solution was added.

In the dialysis tubing bag experiment, if glucose and I2KI are present inside the bag, the color of the I2KI solution will turn blue-black due to the reaction of iodine with starch present in the glucose solution. This color change indicates the presence of glucose inside the bag.

There are many different things that are measured and tested by the data collected in an experiment. Color changes are one thing that can be measured and tested for example.
The independent variable in the experiment is the treatment that is being applied to change the flower petals' color (e.g., dye, chemical solution). The dependent variable is the observed change in the color of the flower petals due to the treatment applied.
A solution can still contain color, but also be clear. Take a pool for example, the water is slightly blue but you can still see through it. A colorless solution is when there is no color, like water in a store bought water bottle.
copper sulphate solution-blue sodium chloride (salt) solution-clear sodium nitrate solution- white to clear sodium sulphate solution- white copper sulphate solution-blue sodium chloride (salt) solution-clear sodium nitrate solution- white to clear sodium sulphate solution- white
There is no relationship between hair color and mental problems.
Lugol's solution is a solution of iodine (1-5%) and potassium iodide in water. So the solution should have the pale color of iodine and the color should be pale (light) brown.
