(Arrange from largest to smallest) 1. 2- Which is the unit of measurement used for liquids? 3 Name the piece of lab equipment used to measure liquids. 4- How would you measure the volume of an irregularly shaped objeet? 5- What are the advantages of using micropipettes? 6- If you are using the 4x objective, what would be the total magnification of the 7- What stain did you used to make the cell visible under the microscope? - What three structures could you see in the cells and what are their functions? microscope you used in the lab? four biological macromolecules are: hydrates provide to the body while fats and oils provide for life activities.Explanation / Answer
1.
Centimeter is larger than millimeter and micrometer.
And largest to smallest is
Centimeter>millimeter>micrometer.
2.
Liter is unit of measurement for liquid.
3.
Name of the piece of lab equipment which used to measure liquid are..
Beaker, flasks, graduated cylinder,burets,pipets and volumetric flasks etc.
4.
Method...
(1).Find a container that can comfortably fit the object you are measuring.
(2).fill it with the water and Mark the water level then drop the object into the water and see if If the object floats, attach a dense, heavy item to it and continue on to measure the volume of both combined. After you write down that result, repeat this method with the heavy item alone to find its volume. Take the combined volume of both items (your first result), then subtract the heavy item's volume. The answer is the volume of the original object.
(3).make the second mark where the new water level is
Now finally
Since you know the water rose from one level to a higher level when the object was submerged, the volume of space between those two levels is the volume of the object. This is called the displacement method, and works because an object submerged in water always "displaces" an amount of water exactly equal to its volume. Depending on what type of container you used, there are different ways to calculate the volume of this displaced water, which is the same as your object's volume. Finish the problem by continuing on to the step that matches your container's description.
