🗑
evolution   descent with modification  
🗑
natural selection   organisms that have certain favorable traits are better able to survive in and reproduce successfully, than those without these traits

independent variable   in an experiment the factor that is deliberately manipulated  
🗑
dependent variable   in an experiment the factor that changes as a result of manipulation of one or more other factors  
🗑
theory   an explanation for some phenomenon that is based on observation experimentation or reasoning that is supported by a large quantity of evidence and doesn't conflict with any experimental results or observations  
🗑

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
 
To hide a column, click on the column name.
 
To hide the entire table, click on the "Hide All" button.
 
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
 
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
