1. You are an archaeologist studying prehistoric human populations in Peru. You want to determine the age of a carbonized corn cob from a site you excavated, which you hypothesize to be 3,000 yBP. Which chronometric method would be appropriate for testing your hypothesis

Radiocarbon dating (or carbon-14 dating). This is a type of chronometric techniques used to determine the age of an organic material by using radioactive isotopes of carbon. It is used by archaeologists and environmental scientists. Radiocarbon dating can span dates from a few hundred years ago right back to approximately 50 000 years ago.

Explanation:

Chronometric dating also called absolute dating is an archaeological dating technique used to give results in calendar years before present time. Chronometric techniques include:

there are mainly three domains in biological classification namely; archaea, bacteria, and eukarya.

archaea includes all the prokaryotic cells which are characterized by their lipid membranes. they have branched hydrocarbon which is attached to glycerol through an ether linkage.

bacteria includes all the prokaryotic cells, the cell membrane of which are made up of the unbranched fatty acid chain. in addition, they are attached to glycerol through an ester bond.

eukarya includes all the eukaryotic cells, that is, the cells contain a nucleus and other membrane-bound cell organelles.

they can be autotrophic as well as heterotrophic, unicellular as well as multicellular

they include kingdoms like protista, plantae, animalia, fungi et cetera.
