The value of gene frequency or allele frequency always resides between 0 and 1. true or false​
Mandarinka [93]

Answer:

true

Explanation:

The value of gene frequency always exists between 0 and 1.

For example, if all of the alleles in the pea plant population were tall alleles (represented as “T”) and none of the alleles were dwarf alleles (represented as “t”), then the “T” allele frequency would be 100% or 1, and “t” allele frequency would be 0% or 0.

For each of the formulas, classify the formula as either an empirical formula, a molecular formula, or both. NaHCO3 empirical mo
shutvik [7]

Answer:

Both

Explanation:

Baking soda is the common name of  sodium bicarbonate or sodium hydrogen carbonate. Both the empirical and molecular formula of sodium bicaronate is NaHCO3 .

Baking soda is soluble in water and has a molar mass of almost Molar mass: 84.007 g/mol.

If we look at molecular formula of NaHCO3, it has molar ratio of 1:1:1:3 and we can say that every thing in this molar ratio make whole mass as : 23g +1 g +12 g+48 g= 84 grams.

Since we know that empirical formula demonstrates the simplest ratio of elements present in a compound and molecular formula demonstrates the total molar ratio of each element in a compound, hence we see that its empirical and molecular formulas both are already simple because they have simplest ratio which cannot be simplified further.

Hope it help!
