e. The seaweed can potentially provide more food for humans than the seal meat can.
Explanation:
The correct statement from the given option is that the seaweed can potentially provide more food for humans than the seal meat.
The seaweed in the arctic ecosystem is the produce. It takes solar through photosynthesis and converts into chemical energy.
- In the food chain, the amount of energy and biomass diminishes as we ascend.
- The most abundant energy is in the producers which are the seals.
- Humans have least available energy.
- The seal is a consumer but at a lower level.
- Since energy transfer among the trophic level is not 100% efficient, we expect that the seaweed is potentially able to provide more food of humans than the seal meat can.

Answer:
Option B, Transcription that originates at the core promoter and +1 site
Explanation:
In basal transcription process a special class of transcription factors which are nothing but the protein that binds to specific sites on DNA (which are also known as promoter sites) with an objective of activating transcription of genetic information from DNA to RNA , specifically messenger RNA. The transcription initiation requires association at promoter site(or regions of DNA that are found in the upstream of the coding region of a gene) along with a σ sub unit
Hence, option B is correct
1. turn off the water when brushing your teeth
2. turn of the lights when leaving a room
3. turn off the lights in the morning and use sunlight coming through the windows to light the rooms
