The answer to this question is 1.DNA because RNA is single stranded.
A physical factor that influences an ecosystem is called an "abiotic factor."
Water,Nitrogen, phosphorus and carbon are items that are cycled through the biosphere in biogeochemical cycles.
Explanation:
- Biogeochemical cycles maintain the balance of elements and compound in nature.
- These help the chemical substances to circulate through different spheres of the earth.
- They are, water cycle, sulphur cycle Nitrogen cycle, Carbon cycle ,Phosphorus cycle etc.
- If the biogeochemical cycles were not present then elements such as nitrogen , phosphorus carbon should have got completely used up instesad of getting replenished. Thus, making several metabolism stagnant.
The term apomorphy means a specialized or derived character state; plesiomorphy refers to a primitive or ancestral trait. An same as autapomorphy is a derived trait that is unique to one group, while a same as synapomorphy is a derived trait shared by two or more groups.
The bond between CH2 and P of phosphate through O is called phosphoester bond. Only one such bond is present in both AMP and ADP.Link of phosphate groups through O by elimination of water molecule is called phosphoanhydride bond.In AMP, only single phosphate group present so no phosphoanhydride bond is present. But inADP, two phosphate groups are linked by one phospoanhydride bond.AMP 1 0ADP 1 1
