Her conclusion is invalid because using sand instead of soil slows down plant growth. Fertilizer, on its own, does not 'greatly' increase the size of the plant.
The correct way to do this experiment would be to keep all other parameters same, except the fertilizer. This will give her accurate results.

<h3><u>Answer;</u></h3>
It combines with water to form glucose.
<h3><u>Explanation;</u></h3>
- Photosynthesis is a process by which green plants make their own food by using solar energy from the sun, together with water and carbon dioxide.
- Carbon dioxide, water and light are all needed for photosynthesis to take place. During the process solar energy from the sun is used to convert carbon dioxide and water into the simple sugar glucose.
- <em><u>Substance A is the above question represent carbon dioxide which combines with water in presence of light to form simple sugars and oxygen gas.</u></em>
- The equation for the reaction is;
6CO2 + 6H2O + light energy = C6H12O6 + 6O2.
Reactions involving fire are typically characterized as combustion reactions in which a material is oxidized, producing carbon dioxide, water, and carbon monoxide in some incomplete combustion reactions.
Carbon dioxide concentrations in soil are higher than in the atmosphere because of respiration of the plants, their roots. Also, CO2 is inhigherr concentration because of the decomposition of organic matter. Decomposition of organic matter produce more CO2 because of increased microbial activity. CO2 concentrations can change as a result of temperature change or different soil structure. Composition of air in soil and atmosphere of CO2 is

Answer:
A diploblast has no mesoderm.
A pseudocoelom has the same functions as a true coelom. In a coelomate, the tissue lining the inner side of the body cavity arises from the same germ layer as the tissue lining the outer side of the body cavity.
Explanation:
Diploblast organisms are the ones that have only two primary germ layers. These organisms have outer ectoderm and inner endoderm but no mesoderm. Example: Cnidarians
A true coelom is derived from mesoderm and is completely lined with tissue derived from mesoderm. The outer and inner linings of the coelom are made of muscle layers that are developed from the mesoderm.
A pseudocoelom is the one that is incompletely lined with mesoderm. Both pseudocoelom and a true coelom serve as shock absorber and provide space wherein the internal organs can be placed. The fluid present in them sere as medium for transport of nutrients, gases, etc.
