Why do scientists use scientific names for organisms?

Scientists need to use scientific names for multiple reasons. Here are three of these reasons. First, it is to avoid confusion. You see, many organisms share a common name and differs from place to place. If scientists used the common names, it could lead to incorrect data. Another reason is that it describes an organism. It brings out the organisms certain characteristics. Lastly, Latin will not change over the years. As you most likely know, Latin is a dead language, or not spoken anymore. These are three reasons why Scientists use the scientific names instead of the common names.


Why are variations in a species needed for natural selection to occur?

What would be selected if organisms did not have differences that lead to better survival and reproduction, or the opposite. That is all natural selection is.


Did controlled experiments or multiple observations lead to the generalization that all organisms are composed of cells?

controlled experiments!


Sexual reproduction in complex organisms?

Although sexual reproduction involves more time and energy, higher organisms have resorted to sexual reproduction in spite of its complexity. This is because this mode of reproduction helps introduce new variations in progenies through the combination of the DNA from two (usually) different individuals. These variations allow the individual to cope with various environmental conditions and thus, make the organism better suited for the environment. Variations also lead to the evolution of better organisms and therefore, provide better chances of survival. On the other hand, asexual reproduction does not provide genetic differences in the individuals produced.princer66.webgarden.com


Why must there be variations in the population in order for natural selection to occur?

Natural selection works via a simple mechanism: certain organisms, though mutation, will be better-equipped for survival than others of their species. Over time, the better-adapted organisms will have a higher survival rate and, through interbreeding and simply outliving the competition, will eventually replace them. If there was no variation (mutation) in the population, there would be no better-adapted individuals, and no change. This has been the case with some species. Alligators, for example, have been around virtually unchanged (except for size) for nearly 100 million years. They are well-adapted adapted for survival in their environment as it is, and thus there is really no need for improvements that would lead to major evolutionary change.

What can you learn about objects by classifying them?

you can trace the evolution of organisms backwards. this enables scientists to understand the species better as well as the living and climatic conditions on the early earth.

Why do scientists use scientific names for organisms when they report on their research?

Many orgnisms have several common names. Using those could lead to confusion.


The rise of photosynthetic organisms did not?

The rise of photosynthetic organisms will not ever lead to a decrease in oxygen. The use of these organisms will always lead to an increase.

Why you have a consciousness?

Consciousness serves an evolutionary purpose. Conscious beings can make conscious decisions, which can be superior to automatic or instinctual decisions made by organisms that are not conscious. Better decisions lead to better survival.
