There can be several hundred types of ion channels within a single cell. mutations within these channels are known to cause many different diseases, collectively known as channelopathies. with this in mind, discuss whether the many channels provide redundancy within the cell or if they cater to specific, independent functions.

the cold front replaces the warmer air at the ground level changing the wind to be breezy and denser.there is also an immediate drop in the temperature.

substituting a hydrogen atom with a halogen in a hydrocarbon:

- the single bond remains single. a is wrong.

- the bond with hydrogen is as strong as with a halogen. c is wrong

- a hydrocarbon is saturated if there is no double bond. we do not know that so d is wrong.

- carbon will always have four valence electrons. e is wrong.

by elimination, the correct answer is b. the boiling point of the new compound increases.
