For each description, write whether it is diffusion, osmosis or active transport 1. If an animal cell is placed in distilled water, water will move into the cell, causing the cell to swell and burst.

2. A cell has a 50% sugar solution. It is in a beaker that has 10% sugar solution. Sugar moves from the cell to the beaker.

3. A cell is observed to have no sugar inside when it is placed into a concentrated sugar solution. After 10 minutes, there is sugar inside the cell. How did the sugar get into the cell?

Interpret the model. a three-part model with black right-arrows between the parts. left part: a large green apple-shaped component with a w-shaped indentation centered on top. a small blue apple-slice shape sits above the left indentation and an arrow points from the shape to the indentation. a small purple apple-slice shape and arrow sit above the right indentation and an arrow points from the shape to the indentation. middle part: a large green apple-shaped component with a square indentation centered on top. sitting in the left side of the indentation is a blue apple-slice shape with a flat bottom, fused to a purple apple-slice shape with a flat bottom on the right side of the indentation. right part: a large green apple-shaped component with a w-shaped indentation centered on top. an up-arrow is centered above the indentation pointing to a fused blue and purple apple-slice-shaped flat-bottom component sitting above the indentation. assigne "true" or "false" to the end of each statement. the model shows a shape change occurring in the enzyme after the substrate is bound in the active site. t/fthere are two products in this model. t? f there are three substrates in this model. t/f the model shows two different enzymes. t/f
