• Less sediment flowed into the river because the fire heated up the soil and made it drier. 
• The amount of vegetation increased and less sediment flowed into the river because the fire produced ash that mixed with the soil. 
• More sediment flowed into the river because the fire destroyed most of the vegetation holding the sediment in place. 
• More sediment flowed into the river because the fire disrupted animal habitats and caused animals to leave the area. 

• The functions of living things occur in cells. 
• Cells exist only in multicellular organisms.
