Which of the following best compares the structures in protists and fungi that allow these organisms to explore their environment.
Protists and fungi move using cilia, flagella, and hyphae.
Some protists move using cilia and flagella. Fungi do not move but have fast growing hyphae.
a. Protists move using hyphae. Some fungi move using cilia, and flagella.
Neither protists nor fungi have cilia, flagella, and hyphae. They obtain energy
only if the food source moves by them.

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.
