Answer:

The last one, to swim

Explanation:

The function of cilia and flagella move liquid past the surface of the cell. For single cells, such as sperm, this enables them to swim. For cells anchored in a tissue, like the epithelial cells lining our air passages, this moves liquid over the surface of the cell (e.g., driving particle-laden mucus toward the throat).

what is a molarity of a solution in 9.8 moles of sodium chloride NaCL is dissolved in water to a final volume 3.2 l
Anika [276]
Answer:
molarity = 3.0625 M

Explanation:
Molarity can be calculated using the following rule:
molarity = number of moles of solute / volume of solution

We are given that:
number of moles of solute = 9.8 moles
volume of solution = 3.2 liters

Substitute with the givens in the above equation to get the molarity as follows:
molarity = 9.8 / 3.2
molarity = 3.0625 M

Hope this helps :)

Answer:

0.028578 km

Explanation:

The following data were obtained from the question:

Length of whale (in mm) = 28578 mm

Length of whale (in km) =?

We can convert 28578 mm to km by doing the following:

Recall:

1 mm = 1×10¯⁶ Km

Therefore,

28578 mm = 28578 mm × 1×10¯⁶ Km / 1 mm

28578 mm = 0.028578 km

Thus, 28578 mm is equivalent to 0.028578 km

The length of whale (in km) = 0.028578 km

DochEvi [55]
3% = 0.3
.03*540 = 16.2
540-16.2 = 523.8

Meaning 16.2 milliliters alcohol and 523.8 milliliters water. If my math is correct.
