Answer:
See explanation!
Explanation:
To answer this, it would be helpful to first determine what natural selection is. Natural selection is a biological process in which species evolve and adapt over time, in order to better fit their environment.
In any ecosystem, there are going to be limited resources. This simply means that species that are most suitable for the environment will survive and have the chance to reproduce.
This means that the environment determines when natural selection happens, but also what it looks like.
This might be better understood with an example:
For example, after several volcano eruptions in a stretch of the desert, the field mice population, over the next generations, gradually became black, rather than their original tan color.
This is because the vast desert sands were replaced with large patches of black volcano rock, so the mice that were previously able to camouflage and avoid detection by predators now weren't able to.
On the other hand, genetically mutated black field mice now had a far greater chance of surviving, and hence the population of field mice gradually became black.
This example illustrates how a change in the environment, caused the process of natural selection and ultimately the characteristic of having black fur to be more advantageous.
Over time, the process of natural selection made it so that the field mice population was black.

B) the hypothesis is tested extensively and competing hypothesis are eliminated
C) there are no other competing hypothesis
D) the hypothesis can be tested at least once
2) A preliminary untested explanation that tries to explain how or why things happen in the manner observed is a scientific ________.
A) law
B) theory
C) fact
D) hypothesis
1) The answer is: B) the hypothesis is tested extensively and competing hypothesis are eliminated.
Theory is a tested, unifying explanation for a set of verified facts.
Theory is a system of explanations that ties together a lot of facts.
Steps of the scientific method:
1) ask a question about something that is observed.
2) do background research.
3) construct a hypothesis, an attempt to answer questions with an explanation that can be tested.
4) test of hypothesis.
5) analyze collected data and draw a conclusion.
2) The answer is: D) hypothesis.
Hypothesis is a suggested explanation for an observable phenomenon.
Experimenters may test and reject several hypotheses before solving the problem.
A working hypothesis is provisionally accepted as a basis for further research.
A law in science is a generalized rule to explain a body of observations in the form of a verbal or mathematical statement.

Why are dichotomous keys useful in classifying a new species?
Answer:
By comparing the traits of other species to that of an undefined species. Even if it is a new species, it can be classified under a specific species type through dichotomous keys.
