5. The following reaction between fluoroacetamide and thiol usually does not occur as an organic reaction. However, researchers have made it work when they incorporated fluoroacetamide into a protein as a side chain of an unnatural amino acid, which then reacted with a cysteine residue of another protein when these two proteins formed a complex. (a) Explain why the given organic reaction does not work. (b) Explain why fluoroacetamide reacts with cysteine in the protein complex. The direct participation of other amino acid residues in the reaction is negligible

d concave shape of wave rock

explanation:

the concave shape of wave rock is a very good evidence that supports the evolution of earth due to chemical weathering. if we talk about structure of   wave rock, studies have estimated that it is around 2.7 billion years old. it also serves as the foundation of evidence that it was the place where australian continent began to form.

how the structure of wave rock was created?

studies suggest that structure of wave rock was created when the surrounded area was started to weather due to which deposition of material started on the part of land which now contains wave rock.

the structure of wave rock is considered to be one of the best-known landforms in australia. at the height of around 15 cm, there can be found flared slopes which formulate the margins of hyden rock. it is now assumed by geologists that wave rock was created by subsurface water-induced weathering and not by glaciers, waves or wind.

due to deposition of material over the period of long time, the wave rock became tougher and tougher due to weathering from surrounding terrain. this makes it a physical evidence that supports   the evolution of earth due to chemical weathering.

hope it !

a "theory" a suggestion that is not 100 % accurate, or a figure. some people say its a theory because they of all the passed theory's about one subject. it depends sometimes theory might be accurate and sometimes they are.

examples of nucleic acids are deoxyribonucleic acid (dna) and ribonucleic acid (rna).

actually the answer is c
