What would be the next step in this experiment?
A. construct a hypothesis and record data
B. make observations and draw a conclusion
C. ask questions and construct a hypothesis
D. analyze the results and make a conclusion
The answer is D
Explanation:
According to this question, a student performs an experiment where she places apple fruit on one location and places apple and banana together in another location. She follows the steps of the scientific method in performing this experiment.
The steps involved in the scientific method include:
- Making an observation
- Constructing an hypothesis
- Testing the hypothesis (experimentation)
- Analyse the result
- Draw a conclusion
The student in this question has already made the observation that when bananas are kept near other fruits, the other fruits ripen faster. She has hypothesized that bananas must have an influence on the ripening process. She tests the hypothesis via an experiment described above. Hence, the next step is to ANALYZE THE RESULTS she will get after 5 days and DRAW A CONCLUSION based on that.
Here are the four postulates of natural selection, according to Charles Darwin:
1. variability - refers to different mutations that create different species
2. heritability - refers to the genes that are passed from one organism onto its descendants
3. overproduction of offspring - refers to the fact that more "children" is born than dies
4. natural selection - refers to those organisms that survive because they adapt to their surroundings better than those who will die
