1. Emergent properties of a cellular life:
2. scientific method of inquiry:
4. Hypothesis and Theory:
Hypothesis is a possible answer that can be tested. It is generally based on the little evidence where the further investigation is required to prove it.
Theory is a statement that is accepted for a hypothesis. Theory can be called 'A tested hypothesis'. After many experiments scientists come to a conclusion about a hypothesis and from then the hypothesis can be called a theory.
5. Importance of controls:
Control is an essential part of many scientific experiments. It helps to minimize the affects of variables of the experiment. It acts as a base line or reference to compare the results at the end of the experiment by minimizing the affect of unknown external and inernal factors.
6. Variables in Francesco Redi's experiment:
9. Evolution:
10. Assumptions of Biological science:
There are three basic assumptions in biological science inquiry. It basically works on the assumptions,
11. Limits of science:
science has its limits
What is science:
What is not science:
Science is not a process in which a conclusion is based on just faith and belief. Science always needs evidence. Generally it go with probabilities rather than certainities.
