At what levels do biologists study life?
andriy [413]

This is to protect and inhibit other biologist in killing thousands of these living organisms and prevent them from becoming extinct. Remember that biologists or any other scientists study because of knowledge and to contribute to the scientific world of making the ecosystem including us into a much better and cultured place and not the opposite.

Hence, there are non-experimental and experimental approaches which are all subject to ethics. In exploring life forms, it is quite unlimited but studying life forms in experimental sense, it is somehow depends on the number of species that the biologists’ study.

On the other hand, the proportion of female sufferers will be definitely less than 8%, for 92% of the remaining male population are neither carriers nor sufferers; and the 8% male sufferers are strictly needed to give the disease X-chromosome for a female to have the trait XX.
