b. In the electron transport chain, a series of reactions moves electrons through carriers.

d. Coenzyme Q and cytochrome c are components of the electron transport chain.

Explanation:

Electron transport chain, commonly known as ETC, is the third process that occurs in aerobic (oxygen needed) cellular respiration. It is the process whereby electrons move across molecules in a series of redox (reduction & oxidation) reactions.

The aim of the ETC is to create a proton pump that will generate power for the synthesis of ATP, which alongside water, is the end product of the process. The Electron transport chain includes protein complexes and electron carrier molecules. Coenzyme Q, also known as Ubiquinone, and Cytochrome C as mentioned in the options are part of the complexes that makes up the transport chain.

many phylogenetic trees have a single lineage at the base representing a common ancestor. a lineage that evolved early from the root and remains unbranched is called basal taxon. when two lineages stem from the same branch point, they are called sister taxa.
