Which cube had the largest surface area?
Question options:
1.0 cm Cube
2.0 cm Cube
3.0 cm Cube
All surface areas were equal
Question 2 3 / 3 points
Which cube had the largest volume?
Question options:
1.0 cm Cube
2.0 cm Cube
3.0 cm Cube
All cubes were equal in volume
Question 3 0 / 3 points
Which cube had the largest surface area/volume RATIO?
Question options:
1.0 cm Cube
2.0 cm Cube
3.0 cm Cube
all cubes had an equal surface area/volume ratio
Question 4 3 / 3 points
How do we know that vinegar has diffused into the cube?
Question options:
By measuring the amount of vinegar left in the beaker
The agar blocks contain a chemical indicator that turns colorless in the presence of acidic substances
The agar blocks contain a chemical indicator that turns colorless in the presence of basic substances
By looking at the agar cubes before the experiment
Question 5 0 / 3 points
What was the rate of diffusion?
Question options:
3 mm/min
3 cm/min
0.6 mm/min
0.6 cm/min
Question 6 0 / 3 points
Which cube had the vinegar diffused through it fastest?
Question options:
1.0 cm Cube
2.0 cm Cube
3.0 cm Cube
All red dots were the same size
Question 7 0 / 3 points
What do our results indicate about diffusion rates and surface area/volume ratios?
Question options:
There is no correlation between diffusion rates and surface area/volume ratios
the smaller the surface area/volume ratio, the higher the diffusion rate
The larger the surface area/volume ratio, the higher the diffusion rate
The surface area/volume ratio does not affect the diffusion rate.
Question 8 0 / 4 points
If the agar samples were cells, which cell would be more efficient at using diffusion to move molecule in and out of the cell?
Question options:
1.0 cm Cube
2.0 cm Cube
3.0 cm Cube
All the same efficiency
I REALLY NEED HELP IF U GUYS HAVE ALL ANSWERS RIGHT I WILL GIVE U BRAILEST OR WHATEVER ITS SUPPOSE TO BE BUT U I WILL REPORT IF U GUYS DONT HAVE THE RIGHT ANSWERS SO PLZ HELP THO.

When in solution, a molecule that moves slowly across an artificial membrane moves rapidly across a plasma membrane. this molecule rapidly enters the cell regardless of whether its concentration is higher inside or outside the cell. using this information, which transport mechanism is most likely to be responsible for the movement of the molecule across a plasma membrane? view available hint(s)when in solution, a molecule that moves slowly across an artificial membrane moves rapidly across a plasma membrane. this molecule rapidly enters the cell regardless of whether its concentration is higher inside or outside the cell. using this information, which transport mechanism is most likely to be responsible for the movement of the molecule across a plasma membrane? active transportexocytosis
