How is oxygen made aboard a spacecraft? The electricity is generated by the station's solar panels and supplied to the oxygen generators through the station's power grid. The water gets delivered to the station from Earth by Progress supply ships and the space shuttle.

Monitoring Volcanic Gases Secondary gases are also commonly emitted from volcanoes and include hydrogen sulfide (H2S), hydrogen (H), carbon monoxide (CO), hydrogen chloride (HCl), hydrogen fluoride (HF), and helium (He). The greatest potential hazards to humans, animals and agriculture are SO2, CO2 and HF.he spectrometer is designed to measure the concentration of sulfur dioxide (SO2) in the volcanic plume that is emitted from the volcano. The device requires a standard, from which to analyze the ultraviolet light absorbed by the SO2 molecules in the plume.

Cellular respiration When oxygen is present, acetyl-CoA is produced from the pyruvate molecules created from glycolysis. When oxygen is present, the mitochondria will undergo aerobic respiration which leads to the Krebs cycle. However, if oxygen is not present, fermentation of the pyruvate molecule will occur.ermentation is less efficient at using the energy from glucose: only 2 ATP are produced per glucose, compared to the 38 ATP per glucose nominally produced by aerobic respiration. This is because the waste products of fermentation still contain chemical potential energy that can be released by oxidation.

- On the bottom of the ocean around deep-sea hydrothermal vents, there is a profusion of life that thrives on the hydrogen sulfide (H 2 S) gas released from the vents. Some of the most impressive of the creatures that live here are the giant tube-worms.eep Sea Hydrothermal Vents. Throughout the oceans of the world there exist undersea mountain ranges, which have formed as result of volcanic activity. These are formally known as rift zones – where the movement of tectonic plates is tearing the earth’s crust apart.

Insects in High Oxygen Environments When we breathe in air at sea level, the atmospheric pressure of about 14.7 pounds per square inch (1.04 kg. per cm. 2) causes oxygen to easily pass through selectively permeable lung membranes into the blood. At high altitudes, the lower air pressure makes it more difficult for oxygen to enter our vascular systems. The result is hypoxia, or oxygen deprivation. Hypoxia usually begins with the inability to do normal physical activities, such as climbing a short flight of stairs without fatigue.

Hydrothermal vent A hydrothermal vent is a fissure in a planet's surface from which geothermally heated water issues. Hydrothermal vents are commonly found near volcanically active places, areas where tectonic plates are moving apart, ocean basins, and hotspots. black smoker or sea vent is a type of hydrothermal vent found on the seabed, typically in the abyssal and hadal zones. They appear as black, chimney-like structures that emit a cloud of black material.

Geological history of oxygen In the absence of plants, the rate of oxygen production by photosynthesis was slower in the Precambrian, and the concentrations of O 2 attained were less than 10% of today's and probably fluctuated greatly; oxygen may even have disappeared from the atmosphere again around 1.9 billion years ago.

- Category: Biology Published: January 5, 2013. All of earth's oxygen does not come from trees. Rather, the atmospheric oxygen that we depend on as humans comes predominantly from the ocean. According to National Geographic, about 70% of the oxygen in the atmosphere comes from marine plants and plant-like organisms. These ocean-living plants release molecular oxygen as a waste product of photosynthesis (as do most plants).

- Answer 1: The oxygen that we currently find in the air has two main sources. The first, and major, source is that oxygen is liberated as a by-product of photosynthetic chemical reactions. The second source occurs in the atmosphere itself when water molecules are split apart after being struck with ultraviolet radiation. This process is called photolysis. The molecule is broken down into one diatomic hydrogen molecule and one free oxygen. The hydrogen molecule is light, and has a quick thermal velocity,so it can escape Earth's atmosphere leaving behind the free oxygen to form a diatomic oxygen molecule. The main source of this atmospheric water was volcanic eruptions and outgassing. Basically before photosynthesis began on large scales, free oxygen molecules in the atmosphere were drawn down in oxidation reactions with free metal ions on the Earth's surface, mainly iron.

Hydrothermal vents Hydrothermal vents-black smokers, white smokers and warm water vents-are areas on the sea floor where water heated by volcanic activity under the seabed gushes out. Unusually, the animal communities down here don't use the sun to get their energy. Instead, chemicals in the hot waters form the basis of the food chain.

What is a hydrothermal vent? Hydrothermal vents are the result of seawater percolating down through fissures in the ocean crust in the vicinity of spreading centers or subduction zones (places on Earth where two tectonic plates move away or towards one another). The cold seawater is heated by hot magma and reemerges to form the vents. Seawater in hydrothermal vents may reach temperatures of over 700° Fahrenheit. Hot seawater in hydrothermal vents does not boil because of the extreme pressure at the depths where the vents are formed.

earth science The oxygen passes into the atmosphere and the hydrogen joins with carbon dioxide to produce biomass. When living things need energy they take in oxygen for respiration. The oxygen returns to the atmosphere in the form of carbon dioxide. Oxygen gas is fairly soluble in water, which makes aerobic life in rivers, lakes and oceans possible. Natural abundance. Oxygen makes up 21% of the atmosphere by volume.

- A hydrothermal vent is a lot like an underwater geyser. Sea water seeps down into the cracks and fissures created by the spreading of the sea floor, sometimes as much as two or three miles into the earth’s crust. As the water comes into contact with the veins and channels of superheated, molten magma, the sea water is superheated.

Anaerobic respiration Anaerobic respiration is a form of respiration which does not use oxygen. Elements other than oxygen are used for electron transport. Common replacements for oxygen are nitrates, iron, manganese, sulfates, sulfur, fumaric acid and carbon dioxide. Escherichia coli uses nitrates and fumaric acid for respiration.

Ecosystem Processes That Produce Oxygen. 1  Plants - Plants create the majority of the oxygen we breathe through a process called photosynthesis. In this process plants use carbon dioxide, sunlight, and water to create energy. 2  Sunlight - Some oxygen is produced when sunlight reacts with water vapor in the atmosphere.
