Cochlear Inner hair cells (IHC) transmit sound stimuli by releasing the neurotransmitter glutamate onto the afferent nerve fibers (type 1 Spiral Ganglion neurons (SGN)). SGNs have α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid receptors (AMPARs) on their post synaptic surface, which is the major receptor involved in Ca2+ influx during sound perception. During excess sound (noise) the IHCs release excess glutamate and this leads to increased influx of Ca2+ in the SGN leading to excitotoxic trauma

Plants and other living organisms use the sunlight to produce oxygen (O2) and glucose (C6H12O6)
INTRODUCTION Photosynthesis is a chemical process in which plants, algae and certain bacteria produce oxygen and glucose using the energy from the sunlight. This process is important for life because of the oxygen and glucose released; these products are used in many life processes. Photosynthesis takes places in a wide variety of organisms and also comes in different forms; these include a form of photosynthesis that does not produce oxygen which is called anoxygenic and the other form which does

Mesocosm Design Lab (Practical #5) Anshul Krishnan : 11M Task: Design, set up, monitor and evaluate a sealed mesocosm, with a view to achieving a sustainable model. ———————————————————————————————————————— Defining The Problem: A Mesocosm is a designed natural environment which can be manipulated and can be controlled. The Main purpose of building a mesocosm is to be able to observe nature’s balance without human intervention; something that has been destroying our planet’s environment since
