Answer:speciation
Explanation: Speciation is the evolutionary process by which populations evolve to become distinct species. There are four geographic modes of speciation in nature, based on the extent to which speciating populations are isolated from one another these are allopatric, peripatric, parapatric, and sympatric. Speciation may also be induced artificially, through animal husbandry, agriculture, or laboratory experiments.
Answer: Saturn is farther from the Sun than Earth.
Explanation:
Answer:
Explanation:Following are the techniques or methods or approaches we can say that were used by the scientists to determine the geologic age:
1. Relative age dating
2. Absolute age dating.
3. Radiation measurement.
4. Stratigraphic superposition.
5. The fossil record.
The scientists used the method of relative dating to divide Earth's past in different chunks of time when alike organisms were on Earth. After that, to discover the actual number of years ago that events occurred, the scientists used the method of absolute dating.
Question options:
1. developing a hypothesis to explain collected data
2. proving a theory and writing a new scientific law
3. collecting data through observation and measurement
4. observing and experimenting to test a hypothesis
Answer:
2. proving a theory and writing a new scientific law
Explanation:
Providing a theory and write a new scientific law is not a step of scientific investigation. To prove a law a theory, its take many years of research.
There are steps of scientific investigations below,
1. Make an Observation.
2. Form a Question.
3. Form a Hypothesis.
4. Conduct an Experiment.
5. Analyze the Data and
6. Draw a Conclusion.
These step of scientific investigation does not include to write a theory and scientific law.
<span>Thymine is harder to make, but more stable. DNA needs to keep information safe for a long time, so it makes sense to use thymine. But RNA is made and used quickly, and small mistakes don’t matter as much, so the easier to make uracil does the job.</span>
