Explanation:

wind

water

Explanation:

There are several ways through which plants can move the seed of plants from one place to another. It isn't possible for plants to move their seeds themselves, therefore, there are other methods for their seeds to be moved.

These include fire, wind, animals, organisms, water, fire, water etc. It should be noted that rocks and clouds are not dispersion methods.

Organisms, Wind , Water

Explanation: I got it correct on Edge

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.
