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.
Answer The formula for photosynthesis (abv. photos.) is: Light Energy + Co2 + H20 -----> Carbohydrate + Oxygen As a whole, photos. takes place in the â¦ chloroplasts of a plant cell. There are two main reactions that occur during photos. The light-dependent reaction and the light-independent reaction.
