Answer:
1. Define a Question to Investigate
As scientists conduct their research, they make observations and collect data. The observations and data often lead them to ask why something is the way it is. Scientists pursue answers to these questions in order to continue with their research. Once scientists have a good question to investigate, they begin to think of ways to answer it.
2. Make Predictions
Based on their research and observations, scientists will often come up with a hypothesis. A hypothesis is a possible answer to a question. It is based on: their own observations, existing theories, and information they gather from other sources. Scientists use their hypothesis to make a prediction, a testable statement that describes what they think the outcome of an investigation will be.
3. Gather Data
Evidence is needed to test the prediction. There are several strategies for collecting evidence, or data. Scientists can gather their data by observing the natural world, performing an experiment in a laboratory, or by running a model. Scientists decide what strategy to use, often combining strategies. Then they plan a procedure and gather their data. They make sure the procedure can be repeated, so that other scientists can evaluate their findings.
4. Analyze the Data
Scientists organize their data in tables, graphs, or diagrams. If possible, they include relevant data from other sources. They look for patterns that show connections between important variables in the hypothesis they are testing.
5. Draw Conclusions
Based on whether or not their prediction came true, scientists can then decide whether the evidence clearly supports or does not support the hypothesis. If the results are not clear, they must rethink their procedure. If the results are clear, scientists write up their fi ndings and results to share with others. The conclusions they draw usually lead to new questions to pursue.
Selective pressure could be any phenomena that would most probably alter behavior and fitness of living organisms in an environment. It is the driving force of evolution and natural selection. Thus, selective pressures influence or leads to the evolution of organisms. Some of the organisms will not survive, reproduce thus, some members of the generation will not be able to pass their genes to the next generation.
Answer:sorry if this doesn’t help but The everyday activities of human are constantly degrading the quality of the environment which ultimately results in the loss of survival condition from the earth. Solve Questions. Write a general essay in about 200 words on
