The most simple answer I can think of would be that improper handling can cause damage to the test subject, which would effect the results, making them unreliable.
Answer: Transformation of one thing to another follow cyclic pathway.
Explanation:
In biology the arrows are used to show the conservation of one form of energy into another form. This can be seen in the cyclic pathways in which transformation of one thing occurs into another thing. For example the concept of metamorphosis in insects involves the conversion of transitional immature stage into adult insect by egg, pupa, larva then into adult insect this growth can be represented by the series of arrows.
The level of electrons involved is equal to its valency....
Plants respire all the time, whether it is dark or light, because their cells need energy to stay alive. But they can only photosynthesize when they have light.
The oxidation of water occurs during photosynthetic electron transport during the light reactions of photosynthesis. In the absence of a source of light energy (dark reactions have no direct requirement for light energy), oxygen is not produced.
Answer:
Oxygen
Explanation:
During photosynthesis, oxygen is released. I found this from a quizlet.
