If you want to measure a volume of 8 microliters that could be done with two different micropippetors (the 1-10 uL or 2-20 uL).

Which would you choose to use? Explain your answer

Hey There!

You should choose 1-10 uL pipette !  

Small range  measurement scales are more efficient than large range scale because they give more accurate measurement as they have visible marks on it  small for all measurement.

Answer:

Please see the pictures attached below

The first picture has the values and the second has the formulas to construct the spreadsheet.

Explanation:

To construct the spreadsheet you should do the following:

1. First name the four columns as:

Number of folds

Thickness in inches

Thickness in feet

Thickness in miles

2. In the first column "Number of folds" put the numbers from 0 to 50 in order to calculate the thickness of each fold.

3. In the second column "Thickness in inches" put the following formula to show that each fold of a sheet is equal to multiply by 2 the original fold:

Thickness in inches = (thickness in inches(number of folds-1))*2

When the number of folds is 1, the formula will be:

Thickness in inches = 0.000 * 2 = 0.000

When the number of folds is 2, the formula will be:

Thickness in inches = 0.004 * 2 = 0.008

When the number of folds is 3, the formula will be:

Thickness in inches = 0.008 * 2 = 0.016

When the number of folds is 4, the formula will be:

Thickness in inches = 0.016 * 2 = 0.032

And so on until 50.

3. In the third column you only multiply by 0.08333 the value of inches to convert it to feet.

4. And in the fourth column you should multiply the value of inches by 0.0000157828 to convert it to miles.

What type of metamorphism involves chemical reactions between oceanic lithosphere and warm fluids near mid-ocean ridges?.
Mariulka [41]

Hydrothermal metamorphism involves chemical reactions between oceanic lithosphere and warm fluids near mid-ocean ridges

Hydrothermal metamorphism is most common along mid-ocean ridge spreading centers, where warm seawater percolates through hot, cracked basalt. Metamorphism of basalt occurs as a result of chemical interactions between hot saltwater and basalt. On continents, crustal rocks can be metamorphosed by invading, hot fluids associated with igneous intrusions, resulting in hydrothermal metamorphism.

The interaction of a rock with a high-temperature fluid of changing composition results in hydrothermal metamorphism. The compositional mismatch between an existing rock and the entering fluid causes a series of metamorphic and metasomatic processes.

Hydrothermal metamorphism changes Mg-Fe-rich hydrous minerals like talc, chlorite, serpentine, actinolite, tremolite, zeolites, and clay minerals. Hydrothermal metamorphism is frequently responsible for the formation of rich ore deposits.
