<u>NADP</u> ( <u>Nictoniamide Adenine </u><u>D</u><u>i</u><u>n</u><u>ucleotide Phos</u>p<u>hate</u> ) is the final electron acceptor of the photosynthetic electron transport chain.
No more than five trophic levels are present in an ecosystem, most have only 4.
Orogenic belts occur where two continental plates collide and push upwards to form large mountain ranges. These are also known as collision boundaries .. hope this helps ?
Thymine always pairs with adenine.
