1. Criteria to be 'alive': organization (at different levels, from simple to complex levels), metabolism (ability to break down food, generate energy and make new biomass), reproduction (ability to create new beings that are alike the parents), responsiveness (to changes in environment and other conditions), growth (changes in body size, rates and other physical characteristics), maintenance of homeostatis (maintenance of internal environment at almost uniform conditions), etc. you can think of all these characteristics and compare say, a dog and a plastic ball. A dog will display all these, while a ball will not reproduce, metabolize, grow or respond to changes in environment; and hence is not alive.
2. For this, you will need pictures and images of the listed entities.
3. There are seven taxonomic ranks:(from smallest to largest) species, genus, family, order, class, phylum, kingdom and domain.
4. Binomial name: genus followed by species, such as Homo sapiens and Escherichia coli. The names are always italicized, with genus name capitalized.
5. Observations that lead to natural selection: were made during Charles Darwin's voyage. He observed overpopulation, constancy in numbers, variations in individuals within same population and like produces like. Only the species that are naturally selected or favored by nature (through natural selection) will carry on and others will die out. Evolution of such species will take place over time in order to survive and adaptation will be their only option.
6. A scientific hypothesis must be testable (one can test it), parsimonious, fruitful (has future applications for other works as well), has scope and is falsifiable (is open to testing and can be nullified by a single result).
7.Steps of scientific method: ask a question, do background research, formulate a hypothesis, test the hypothesis, data analysis, conclusion and communication of results.
8. Experimental controls help to compare the data of a situation with or without change and serves as base case.
9. Hypothesis is a suggestion that is up for testing, theory is already tested (substantiated) and is an explanation for a set of verified hypothesis.
