Answer:
The number of red blood cells is approximately 660 times greater than white blood cells (option A).
Explanation:
In adult humans the blood has about 4,5 to 6 million red blood cells per cubic millimeter (mm3), while the normal value of white blood cells is between 5,000 and 10,000 per mm3.
In this exercise, the given values are
To know how many times there are more red blood cells than white blood cells in this sample, only have to divide the amount of the former between the second:
2.600.000 / 3.920 = 663,27 ≈ 660
For given cell values, the number of red blood cells is about 600 times greater than white blood cells.

Answer:
The velocity of the sound waves across the plains of Sneedville is 500 m/s.
Step-by-Step Explanation:
Distance travel by the screech of Sneetches = d = 250 m
Time taken to cove 250 meters = t = 0.50 s
Let the velocity of the sound waves be v, such that:
v = d/t
⇒ v = 250/0.5
⇒ v = 500 m/s
Explanation:
In liquids, force of attraction between the molecules is less as compared to solids but force of attraction between the molecules is more strong as compared to gases.
Also, liquids do not have any definite shape and they acquire the shape or container or vessel in which they are placed.
Therefore, when a liquid is simply transferred from one container to another container then its volume remains the same.

c. radiation that comes from the earth
d. radiation that is absorbed by the earth
Answer:
the answer to the question is calcium
Calcium chloride is the most soluble salt in ice water due to its ability to lower the freezing point of water more than other salts.
When it comes to solubility in ice water, the most soluble salt would be the one that can lower the freezing point of water the most. Sodium chloride (NaCl) and its analogs calcium chloride (CaCl₂) and magnesium chloride (MgCl₂) are often used to melt ice on roads and sidewalks because they have lower freezing points than pure water. Among these salts, calcium chloride would be the most soluble in ice water. The group 2 metal salts, such as calcium chloride, dissociate to yield three particles per formula unit and provide a larger depression of the freezing point compared to sodium chloride, which dissociates to yield only two particles per formula unit.
