Answer:
James Watson and Francis Crick solved the structure of DNA. Rosalind Franklin and Maurice Wilkins, also contributed to this discovery.
Explanation:
Pneumatopores specialized 'breathing' root developed in some plant species that grow in waterlogged or strongly compacted soils, e.g-mangroves. The aerial part of the root contains many pores, enabling gas exchanges with the atmostphere. Internally, a well developed system of incellular spaces allows gases to diffuse throughout the submerged portion of the roots
The oxidation of organic compounds by molecular oxygen to produce CO2 and water releases free energy because electrons are being moved from atoms that have a lower affinity for electrons.
