Question
Answer
show organism whose cells contain nuclei  
🗑
show a single celled organism lacking a nucleus  
🗑
show process in which a virus enters a cell, makes a copy of itself, and causes the cell to burst  
🗑
show process by which a virus embeds its DNA into the DNA of the host cell and is replicated along with the host cell's DNA  
🗑
lytic cycle (5 steps)   show
🗑
lysogenic cycle (5 steps)   show

show virus that infects bacteria  
🗑
independent variable   show
🗑
dependent variable   show
🗑
show virus's protein coat  
🗑

🗑
show cell organelle filled with enzymes needed to break down certain materials in the cell  
🗑
vacuole   show
🗑
mitochondrion   show
🗑
chloroplast   show
🗑
show network of protein filaments within some cells that helps the cell maintain its shape and is involved in many forms of cell movement  
🗑
show one of two tiny structures located in the cytoplasm of animal cells near the nuclear envelope  
🗑


   

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.
