1) Speed = distance / time
s = 60 / 2
s = 30 km/h
In short, Your Answer would be Option B
2) Speed = distance / time
s = 25/4
s = 6.25 km/h
In short, Your Answer would be Option B
[ Direction not needed as it is speed not velocity ]

Answer:
RNA Polymerase plays an important role in the process called transcription which result in the in the synthesis of RNA from DNA molecule.
Explanation:
RNA polymerase helps in the addition of ribonucleotides in the growing RNA strans that is synthesized from template DNA .
one ribonucleotide is joined to the adjacent ribonucleotide by the formation of phosphodiester bond.
RNA polymerase is named so because this enzyme helps in the polymerization of ribonucleotides leading to the formation of a Primary RNA transcript.
Answer: Y represents carbon and z is oxygen which gives CO2
Explanation: To photosynthesis to occur Carbon has to reacts with oxygen to give carbondioxide (Co2) which then combines with hydrogen (H2) and oxygen to give water (H20) the reaction gives glucose (C6H12O6).
Equation for photosynthesis = 6CO2+6H20- C6H12O6
