torr‚ studies have proof that cellular oxygen uptake stay permanently autonomous of oxygen tension. When the carbon-hydrogen bonds of glucose are broken‚ electron are transferred to oxygen. The transfer of electrons during chemical reactions releases energy stored in organic molecules. This released energy is ultimately used to synthesize ATP. The medical examiner concluded that each of the victims had died of hypoxia. At this point‚ the dispersion of oxygen to the mitochondria start to restraint

COPD COPD is characterized by airflow limitation that is poorly reversible. Cumulative‚ chronic exposure to cigarette smoking is the number one cause of the disease‚ but repeated exposure to secondhand smoke‚ air pollution and occupational exposure (to coal‚ cotton‚ grain) are also important risk factors. Chronic inflammation plays a major role in COPD pathophysiology. Smoking and other airway irritants cause neutrophils‚ T-lymphocytes‚ and other inflammatory

→IMPORTANCE OF FORESTS •Forests play a role indispensable for life on earth by absorbing carbon dioxide and fixing carbon while releasing oxygen into air through Photosynthesis‚ particularly‚ tropical forests absorb almost 2-3 times as much carbon dioxide as temperate forests and have thus been called ‘the lungs of our planet’ •Conservation of water resources •Prevention of disasters •Supplying forest products •Sheltering Rich Ecosystems Wholesome influence of forest on environment:

have the chemical structures of Carbon‚ Hydrogen‚ Oxygen and Nitrogen. Proteins have various functions such as making and breaking chemical bonds‚ transport‚ movement‚ signaling‚ regulation and metabolism (cellular process). Peptide Bonds are important while discussing proteins. Peptide Bonds are covalent bonds that join 2 amino acids‚ amino acids are also proteins monomer. Next are Carbohydrates. Carbohydrates incorporate Carbon‚ Hydrogen and Oxygen in a 1:2:1 ratio. They provide short term energy

An atmosphere may be retained for a longer duration‚ if the gravity is high and the atmosphere’s temperature is low. Some planets consist mainly of various gases‚ but only their outer layer is their atmosphere.” Air is mainly composed of nitrogen‚ oxygen‚ and argon‚ which together constitute the major gases of the atmosphere. The remaining gases are often referred to as trace gases‚ among which are the greenhouse gases such as water vapor‚ carbon dioxide‚ methane‚ nitrous oxide‚ and ozone. Filtered

was done to see if abiotic factors such as temperature‚ dissolved oxygen‚ temperature and pH value could have a significant correlation with total percentage of algal cover. Initial hypothesis was dissolved oxygen and pH value are correlated to total algal cover. Each pool sample’s water chemistry were measured and tested for 2 day period. The correlation between dissolved oxygen and algal cover is weak‚ proving that dissolved oxygen is not

rate of Ceratophyllum‚ which is an aquatic and high oxygen producer plant. The alternative hypothesis was that the rate of photosynthesis increases as the distance of the light decreases. This is because light energy can excites chlorophyll molecules more clorophyll mulcoulse as the distance of the light decreases. Photosynthesis is a process in which the energy of light is used to produce organic molecules. In this process Oxygen is released; therefore the rate of photosynthesis
