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.
<span><u>How does fossilized carbon get back into the atmosphere?</u>
</span>Fossilized carbon is coal. One major way it gets back into the atmosphere is by humans burning it in coal power plants. Carbon gets back into the atmosphere as carbon dioxide through the combustion of fossil fuels.

Every organism has a unique ecosystem within which it lives. This ecosystem is its natural habitat. This is where the basic needs of the organism to survive are met: food, water, shelter from the weather and place to breed its young. All organisms need to adapt to their habitat to be able to survive.
Answer: Bottom layer of rock
Explanation:
The bottom layer is the layer of the deposition of the sediments in which sedimentation and cementation occurs to form the rocks. These rocks are formed at the lowest horizon of the soil profile. These rocks are also called bedrocks. The layer present above the rock are younger and the layer at the top is the youngest layer. The older layer at the bottom and the younger layer at the top. This phenomena is called law of superimposition.
