There is a significant difference between parfocal objectives and objectives that are not. Having parfocal objectives means that the sample remains in focus when the objectives are changed.
---------------------------------------------
The most significant characteristic of parfocal objectives is that the image or sample under observation remains focused even when changing objectives.
When you are focussing a sample using a low-power objective and want to change to a higher one, you do not need to refocus anymore. And if you do, the adjustment is minimal. The focus keeps being the same because the distance between the image and the lens remains the same.
This characteristic turns to be convenient because
- <em>it avoids spending time focusing, </em>
- <em>it prevents contact between the lens and the coverslip. </em>

The idea needs to be tested for it to be scientifically reliable. First, a hypothesis has to be drawn up. A simple explanation for the word "hypothesis" is an educated guess. The scientist makes an educated guess in answer to a problem. He then sets about proving or disproving the hypothesis. This is done by setting up related scientific experiments. <span>For the theory to be scientifically proved, the experiments need to be set up in such a way that the results are measurable. </span>
Answer:
Carbondioxide gas.
Explanation:
Carbondioxide gas is actually cycled in a web of organisms, The plants takes carbondioxide gas for the process of photosynthesis, this plant is eaten by herbivores for energy and carbondioxide is released in the process of respiration. After that, carnivores feed on these herbivores and oxygen is used in the breakdown of food for releasing energy and carbondioxide gas is also released from the body through breathing so the cycle of carbondioxide gas is continue.
