Just as stated and also explained, the correct answer is <span>a long chain of adenine nucleotides is added to the 3' end of mRNA during terminationof transcription. That is the only statement that is true about the polyadenylation mechanism. Hope this is helpful</span>
I think it’s A it’s probably wrong or not
I believe it is the 'negative feedback mechanism'
Hope this answers your question.
Answer: Solar panels are made up of silicon cells. This because silicon has high ability for conduction and this make it to be able to convert sunlight into electricity. It is in solar cells has impurities and great chemical properties which make it to be to convert sunlight to electricity.
Silicon
Explanation:
Silicon is an element with atomic number 14, it is a non metal and crystalline solid. It has blue grey metallic lustre. Silicon is made with impurities in solar cells and has special chemical properties to convert sunlight into electricity. It is a semiconductor, a material that can act as a conductor and insulator.
When light interact with silicon cells, it make electrons to be in motion and initiate the flow of electricity, it is called photovoltaic effect.
Silicon alone is not used, it used with metal casing and wiring to ensure proper electric flow.
