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
