Do ladybugs have different numbers of spots because of gender ?

Determining whether a ladybug is male or female has nothing to do with the size or number of black spots on the insect's orange body. Both sexes have these spots. The male is generally slightly smaller than the female. The ladybug's reproductive organs share the abdomen, along with the digestive and respiratory organs.

Explanation:

i don't know people like to fight everywhere rip.

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.
