4.1 Ear anatomy. The ear can be seen as three parts: the outer ear, the middle ear and the inner ear - each with a dedicated function. The outer ear consists of the ear shell (pinna) and the auditory canal. Its function is to guide air pressure waves to the middle ear- with the ear shell increasing the sensitivity of the ear to the front side of the head, supporting front/rear localisation of audio signals.
Photosynthesis occurs in two stages. In the first stage, light-dependent reactions or light reactions capture the energy of light and use it to make the energy-storage molecules ATP and NADPH. During the second stage, the light-independent reactions use these products to capture and reduce carbon dioxide.
Photosynthesis consists of light-dependent and light-independent reactions... as we all know, the reactants of photosynthesis are carbon-dioxide, water and light, and the products are carbohydrates and oxygen... But which reactants and which products are the components of which of the 2 reactions.... The LIGHT-DEPENDENT reaction needs LIGHT in order to split WATER, to give OXYGEN as a byproduct, and the ENERGY (in the form of ATP and NADPH) necessary for LIGHT-INDEPENDENT reaction to take action.
