to be certain that it is a spider
to compare it to similar spiders
to be able to study how other organisms are affected by the species
Let me know of this is wrong??
Natural selection or survival of the fittest can cause a major evolution as the species at risk need to stay alive and therefore need to become more adapted to the situation at hand. The species can evolve through generations to become more crafted to the predatorial habits of their predators. If the females are less at risk than the males then the males might evolve to become more protected or if some of the species live in a different situation maybe not even that far away, that can have a big impact on the evolutionary habits of the species at hand.
I hope I'm right
The
changeable nature of models is considered a limitation because when the model alters,
the answers that were achieved from the model may also transform.<span> <span>What this
means is that outcomes that’s been extracted from changeable models can be true
at a certain moment, place or situation, but the conclusions may not be
objectively true.</span></span>
The atomic number of an isotope is the number of protons it contains, whereas the mass number is the total mass of the nucleus, which is the combined number of protons and neutrons in the nucleus. To find the number of neutrons, you must therefore subtract the atomic number of the isotope from the mass number of the isotope.
<span>In the above example, the atomic number is 8 and the mass number is 18. This isotope is known as O18. The number of neutrons in the isotope is: Mass number - Atomic number = Number of neutrons
