Because a single human can analyse several generations of the species - which can lead to evolutionary traits forming.
circadian rhythms
Provide an explanation for the complex life cycles exhibited by parasitic helminths.
Faster breeding cycles equate to faster rates of evolution and speciation.Additionally their small size means there are more ecological niches for them to fill.
Bouin's is generally used for testicular fixation because it preserves nuclei and chromosomes especially well, such as those you would want to observe during meiosis. Formalin is a more general fixative, used widely for other tissues when mitotic or meiotic cycles are not necessary to observe.
It may be difficult to tell which cycle manufacturer is better between Hero cycles and Atlas cycles. This is mainly due to the fact that they both manufacture quality cycles. However, Hero Cycles has the largest output in India.

Because while we can trace the APPARENT path of evolution yielding the species we see around us, in most instances the transition via evolution is implied, not observed. No one was around to observe when most of the evolutionary splits are believed to have occurred so no one documented them to establish as a known fact that that was how the split occurred. In fact there are quite a few instances where scientists have changed their views on which ancestor a particular species branched off from (usually based on further discoveries). Also - theories remain theories until proven via experiments. It's rather difficult to craft an experiment to test natural evolution over any human time scale, although a limited number of experiments have been conducted via forced evolution of some species with very short life cycles.
The two biogeochemical cycles that depend directly on photosynthesis are the oxygen cycle and the carbon cycle. Photosynthesis is the driving force between these two cycles.

You should observe your cycles for around six months before using the calendar method. It is important to recognize that the calendar method isn't very reliable, it is much better to use the symptothermal method to observe and track your cycles - especially if using these methods as birth control. You can read more about symptothermal methods via taking charge of your fertility.

There are about 500 known species of leeches. most live annual life cycles, however some of the larger species will live longer.
