sexual reproduction

- offspring has a mix of genes from two parents - results in genetic diversity

rank the following steps of the generalized scientific method in order from the 1st step at the top to the last step at the bottom - analyze your data and draw conclusions - create a hypothesis to explain your observations and make predictions - carry out experiment to test the hypothesis and collect data - observe and ask questions about something in the natural world

1. observe and ask questions about something in the natural world 2. create a hypothesis to explain your observations and make predictions 3. carry out experiment to test the hypothesis and collect data 4. analyze your data and draw conclusions

the change in genes of a population over multiple generations can also be referred to as reproduction homeostasis adjustment evolution

evolution

hypotheses are often tested with an investigation called a experiment theory variable peer review
