Answer:
the correct answer is CO2 (the last one)
So visualize soil mixed with water. To separate it, you can use a sieve to filter the water.
Answer:
The fractional saturation for hemoglobin is 0.86
Explanation:
The fractional saturation for hemoglobin can be calculated using the formula

Where
is the fractional oxygen saturation
is the partial pressure of oxygen
is the partial pressure when 50% hemoglobin is saturated with oxygen
and h is the Hill coefficient
From the question,
= 40 mm Hg
= 22 mm Hg
h = 3
Putting these values into the equation, we get





Hence, the fractional saturation for hemoglobin is 0.86.
Answer:
They have the same number of atoms
Explanation:
The mole (symbol: mol) is the base unit of amount of substance.
Think of mole meaning like inch. An inch of grass is the same as an inch of a flower. Mole is the standard measuring unit of atoms.
