found on earth Archaea are single cell micro-organisms with no nucleus‚ it use anaerobic respiration (able to living in the absence of Oxygen) and live in extreme environment/condition such as high temperature‚ acid-rich‚ saline area etc. those environment are rich in minerals but hazardous to other organisms. Archaea’s population decreased after earth filled with oxygen‚ other than that‚ current archaea is very same as ancient archaea. Archaea like to live near Black Smoker (volcanoes under ocean)

through the degrade‚ reduction and loss of oxygen in the water quality.(source) why is it a problem to plants Due to the Hygrophila being quick to over grow within many creeks‚ rivers and wetlands it has caused it to dominate the entire water column. This will result in most plants below being unable to gain sunlight through photosynthesis causing them to die. Soon after‚ bacteria inhabits the area in order to decompose the submerged pants causing mass oxygen levels to be used up Therefore the vegetation

light is because of the oxygen release rate. With more light intensity‚ the rate of photosynthesis happens faster. Since the process of photosynthesis release oxygen‚ the more oxygen will be released creating the bubbles underwater. To clarify‚ photosynthesis is the process of which a plant’s chloroplasts‚ with the aid of the sun (or a flashlight in this situation)‚ break the bonds of H2O (Water) and CO2 (Carbon Dioxide) to form CH2O (Carbohydrates/ Glucose) and O (Oxygen). This means if the plant

Yoga is a vast collection of techniques and practiced all aimed at integrating mind‚ body and spirituality achieving a state of enlightenment or oneness with all living humane animals plants and our universe that we live within. This semester in Hatha Yoga we make the correlation between the two‚ body and mind spiritual aspects will bloom like a flower as our lives and bodies are continual changing. Yoga will not work for everyone at this present time we learn to apply when knowledge is at hand.

disappear. It was the first to evaporate among all tested substances. The reason for this is that this molecule is not attracted to another molecule of Acetone by hydrogen bonding because although there are hydrogen molecules they are not bonded to an Oxygen‚ Fluorine or Nitrogen. In other words it has no H’s that are bonded to F‚ O‚ N‚ or Cl - i.e. there are no slightly positive H atoms. Acetone molecules attract each other since they are both having permanent dipoles. This type of IMF‚ which is weaker

The human body requires many things to function. One of the most important requirements is oxygen. Oxygen is used by the entire body to make energy. The Respiratory System collects and filters the air we breath to get that precious oxygen. The respiratory(breathing) process begins when you inhale and air is taken in through the mouth and/or nose. The air flows into the pharynx(throat) and enters the trachea(windpipe). The air then flows into one of two bronchi‚ left bronchus and right bronchus.

The amount of caloric intake required combined with how much oxygen they use during their main activities could tell us a lot about what it takes to live in such an unyielding and unforgiving environment. But by learning how much energy they use and how they use it we could learn a lot about We measure how much energy it takes an otter to do something by measuring the oxygen consumption during surface behaviors‚ and the oxygen consumption after an otter returns from a dive. This is done using
