The role of 3tc in inhibiting hiv reproduction is to interfere with enzyme trancriptase since it has a similar shape to the c nucleotide of DNA.Reverse trancriptase pick up 3tc molecule which led to termination of DNa further thus block reproduction of HIV.
D. ATP (Adenosine TRIphosphate) has one more phosphate group and is higher in energy than ADP (Adenosine DIphosphate). TRI means three, DI means two, so the names of the molecules tell you there's one more phosphate in ATP than in ADP.
That extra phosphate makes ATP higher in energy (when the cell uses that energy to do something - contract a muscle fiber, for instance - the ATP's extra energy is used and it gets converted to ADP).
A) Stone
They used materials they were available to them which was majorly limestone which is a type of stone.
These groupings are called domains.
<span>A domain is the highest taxonomic rank of organisms. Carl Woese, an American microbiologist, and biophysicist designed the three-domain system which describes that the tree of life consists of three domains: Archaea, Bacteria, and Eukarya. Each of these three domains of life is characterized by rRNA which is unique to them.</span>
