Answer:
the endpoint not pH scale is 14
Classification systems previously were having very different goals than modern classification systems. If we look at old eras, scientists like Aristotle and Theophrastus tried to classify organisms on the basis of apparent characteristics, habitat and simple other traits.
Old classification systems had alot of errors and flaws. For example they classified fish and whale in one group because they lived in water, now we know fish is amphibian while whale is mammal.
So we can say that the goal o earlier classification system were just to make groups of organisms on the basis of External features.
Goal of modern classification system:
Modern classification approach was started by Linnaeus. It focuses more on biological delimitation and evolutionary histories than mere external characteristics. It organizes organisms in groups in such a way that grouping reflects their evolutionary relatedness. It is not just specie level but also focuses on sub-specie and population level classification.
Thus modern goal is better in many terms and is more reliable than old classification goals.
Hope it helps!
Answer:
Explanation:
Even if we stopped burning fossil fuels, the Earth would continue warming up for another few decades because of all the heat we've already produced. Global temperatures would climb – finally stabilizing at a level much higher than we've ever known.
This is evidenced by Doppler
shift effect. This is the phenomenon where waves that are coming from an object
that is accelerating towards your direction are heard at a higher frequency than that of
objects moving away from you. This is the same for light (which also has
wave-like properties). When observing distant galaxies, astronomers discovered that
they all showed to be redshift (change in the frequency of light towards red
color). This means that all galaxies are moving away from each other because
the universe is expanding.
