Answer: A
Explanation: The nervous system sends electric signals from the brain to the body to make they move. The charger is similar becuase it sends energy to your devices so they can work.
Answer: all eukaryotes
Explanation: Plants and animals both preform cellular respiration. Cellular respiration is the process of sugar (glucose) being in the process of transforming into energy for the cells!
The correct answer is: (a) RNA polymerase (along with its sigma subunit) can initiate transcription on its own.
More differences between prokaryotic and eukaryotic transcription:
• In prokaryotes transcription occurs in the cytoplasm (unlike in eukaryotes in nucleus) and it is simultaneous with translation,
• In prokaryotes there is only one type of RNA polymerase (in eukaryotes there are three types of them).
• There is no sigma subunit in eukaryotes, the initiation of transcription begins thanks to initiation factors.
• Promoter region in prokaryotes contains pribnow box, while in eukaryotes it contains TATA and CAT box.
Eukaryotes are larger cells with membrane-bounded organelles.
Prokarotes are not that large and do not have a nucleus or any memberane-bound organelles.
