Answer:
The rate of photosynthesis was more than the rate of respiration
Explanation:
Photosynthesis has to do with the synthesis of sugar molecules from inorganic products such as water and carbon dioxide. Respiration on the other hand has to do with breaking down of the sugar molecule from photosynthesis to release the energy locked up in the sugar for various metabolic processes in the plant's body.
<em>If both processes are balanced, there will be no net sugar production. Hence, if an excess of sugar produced fossil fuels, it thus means that there was net production of sugar in the past. The rate of photosynthesis was more than the rate of respiration in the past.</em>
Answer:
The answer is D
Explanation:
Since the structure uses light energy, we can only assume that it's a chloroplast, since only chloroplasts contain chlorophyll and can absorb light energy.
Chloroplasts use carbon dioxide and water to make glucose, with oxygen as a byproduct.
The glucose produced is then used in metabolic reactions in the organism.
The endocrine system releases hormones into the bloodstream, most of which are released by the pituitary gland
