Answer: Temperature of the air and water affect animals, plants and humans in ecosystems. A rise in temperature has the potential to change the way a living thing develops, because it changes the metabolic rate of the organism. <em>All living organisms have a tolerance level for temperature range.</em>
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>

Inorganic nitrogen compounds are a vital part for the biosynthesis or organic compounds such as amino acids, proteins, nucleic acids etc. Thus, nitrogen fixation is essential for all life to exist, grow and thrive.
The nitrogen fixing bateria that exist withing the roots, stems and leaves of sugar cane give these plants an extraordinarily evolutionary advantage. Due to this mutualistic relationship, the plants are no longer dependent on solely the soil nitrogen content, which in some areas may be low. This increases the plants' survival chances by allowing them to grow in areas where other plants may not survive.

No, the ionosphere is found in parts of the thermosphere and the mesosphere. The ionsphere is where high-energy radiation from the sun has knocked electrons loose from atoms/ molecules, creating ions.
