After collecting specimens from many ares of the world Darwin noticed some similarities in them.
Dna is double stranded
rna is single stranded
sugar in dna is deoxyribose
sugar in rna is ribose
nitrogenous bases in dna are adenine thymine guanine and cytosine whereas rna has uracil instead of cytosine
dna stays in the nucleus
rna leaves the nucleus
Criteria pollutants are simply a list of pollutants created by the EPA, designed to include the 6 most common air pollutants.
B) Carbon dioxide
CO2 is not on the EPA list.

The alkalinity as CaCO3 in mg/L is 108,23
<h3>What is alkalinity?</h3>
Alkalinity is the total measure of substances present in water, capable of neutralizing acids. In other words, it is the amount of substances present in the water that act as a buffer.
With that being said;
Equivalent weight = {molar mass}*{ion charge/oxidation number}
- Molar mass of HCO3- = 61g/mol
- Molar mass of CO3 = 60g/mol
- Molar mass of CaCO3 = 100g/mol
- Eq. cot. of HCO3- = 61g/Eq
- Eq. cot. of CO3 = 30g/Eq
- Eq. cot. of CaCO3 = 50g/Eq
Alkalinity due to CO3 = {32x50}{30} = 53.33mg/L
Alkalinity due to HCO3- = {56x50}{61} = 54,90mg/L
Total Alkalinity = 53,33 + 54,90 = 108,23 mg/L
In this case, we have to The alkalinity as CaCO3 in mg/L is 108,23 mg/L
