Answer asa what was the result of geologists trying to disprove the idea that the continents were all once together as once land mass by testing minerals and fossils on different continents? a) mineral and fossils did not match up to dispute wegener’s theory. b) mineral and fossils matched on separate continents adding evidence in support of wegener’s theory. c) the fossils matched from separate continents but the minerals did not keeping wegener’s idea still unsupported. d) the minerals match from separate continents but the fossils did not keeping wegener’s idea still unsupported.

The Answer Is:

B.

-.-

hydroxyl -oh

alcohols, always polar, can form hydrogen bonds with h2o molecules

carboxyl -cooh  

cargoxylic acids, has acidic properties which is a source of hydrogen ions, found in cells in ionized for with a charge of oh-1

carbonyl > co

ketone if within skeleton, aldehyde if group is at the end of skeleton, k & a may be structural isomers, it determines 2 sugars (ketose & aldose)

amino -nh2

amines, acts as a base, it can pick up h+ ions from surrounding solution, ionized with charge of 1+

methyl ch2

addition to rna/dna affects and gene expression

phosphate -opo3 ²⁻

organic phosphates, contributes to negative charge to, molecule that it is a part of, and potential to react with h20

sulfhydryl -sh

thiols, cross-linking stabilize the protein, and it is structure
