Listed below are blood groups of o, a, b, and ab of randomly selected blood donors (based on data from the greater new york blood program). o a b o o o o o ab o o o o b o b o a a a o a a b ab a b a a a a o a o o a a o o a o o o o a a a a a ab identify the frequency of the blood group o

Frequency = 22

Relative frequency = 44%

Explanation:

Hello,

To find the frequency of the blood group o, we've just got to count the amount of blood group o donors, thus, the result is 22. On the other hand, if you're required to find the relative frequency, you divide the aforesaid result by the total amount of donors as shown below:

answer is: naturally occurring solid, inorganic compound or element is mineral.

minerals usually have crystalline form, that means than crystal constituents (atoms, molecules or ions) are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions.

for example magnetite is a mineral of iron oxide (fe₂o₃).

calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (caco₃).

dolomite is an   carbonate mineral composed of calcium magnesium carbonate (camg(co₃)₂).

hydrocarbons are organic compounds that contain only hydrogens and carbons. they can be saturated (those which contain only carbon-carbon single bonds) or unsaturated (those which contain carbon-carbon double or triple bonds) in nature. hydrocarbons can undergo several reactions like substitution, elimination etc.  

on substituting one or more hydrogen atoms in hydrocarbon it results in the formation of haloalkane. as the halogen atoms are large compared to the carbon and hydrogen atoms, due to which the molecular weight increases and the bond become polar because of presence electronegative halogen atom and results in the increase in boiling point of the haloalkane.

thus, the correct option is (b) that is the boiling point of the new compound increases on substituting a hydrogen atom with a halogen in a hydrocarbon.
