The changing quantities in an experiment are called variables. A variable refers to any trait, factor, or a condition, which can prevail in distinct amounts or kinds. An experiment generally exhibits three kinds of variables: independent, dependent, and controlled.
The independent variable refers to the one, which is modified. On the other hand, the dependent variable is implied to observe that how it reacts with the change made to the independent variable. The controlled variables refer to the quantities, which one wants to remain constant.
In the given case, that is, heating a cup of water to witness that whether the sugar will get more easily dissolve. In this, the independent variable refers to the temperature of the water determined in degrees Centigrade. The dependent variable refers to the amount of sugar, which dissolves completely measured in grams.
In this, the controlled variables are stirring and type of sugar. As more stirring might elevate the amount of sugar that dissolves, and different kind of sugars might dissolve in distinct concentrations. So, in order to make sure a fair test, there is a need to keep these variables similar for each cup of water.
Increasing the temperature might cause proteins within an enzyme to denature. This will cause the enzyme to stop working properly.

Photosynthesis produces glucose and O2 from inorganic CO2, light energy and water. This occurs in distinct steps: 1) light fixation, 2) electron transport and NADPH production 3) ATP generation, then 4) carbon fixation and carbohydrate production.
6CO2 + 6H20 + (energy) → C6H12O6 + 6O2
Further Explanation:
Photosynthesis is a chemical process, essential to plant and other primary producers producing energy. As oxygen is emitted, energy in the form of glucose molecules is created from light, water, and carbon dioxide. It happens in several complicated stages, photosynthesis is a speed-limited process, depending on several factors including concentration of carbon dioxide, ambient temperature and light intensity; energy is extracted from photons, i.e. light particles, and water is used as a reduction agent. It occurs in the thykaloids, where pigment molecules live like chlorophyll.
Photosynthesis occurs in several complex steps and is a reaction of a small duration, depending on several fa factors including carbon dioxide concentration, ambient temperature and light intensity; the energy is retrieved from photons, I.e. particles of light, and water is used as a reducing agent. Water supplies the chlorophyll in plant cell with replacement electrons for the ones removed from photosystem II.
Additionally,
- Water (H2O) divided into H+ and OH-by light during photolysis serves as a source of oxygen along with acting as a reduction agent; it reduces the NADP molecule to NADPH by supplying H+ ions and generates molecules of the energy storage molecule ATP through an electron transport chain.
- This happens in the thykaloids, where pigment molecules reside like chlorophyll.
- Later, NADP and NADPH are used in dark reactions during the Calvin cycle, where monosaccharides or sugars such as glucose are produced after several molecules have been modified. These store energy in their bonds which in the mitochondria can be released in respiration.
