Oxygen is a chemical element with the symbol O and atomic number 8. It is a colorless, odorless, and tasteless gas that is essential for life on Earth, as it is used in cellular respiration to produce energy. In its diatomic form (O2), oxygen makes up about 21% of Earth's atmosphere.

Which term describes the loss of consciousness that occurs when the body cannot get the oxygen it needs?
The term that describes the loss of consciousness due to lack of oxygen is "hypoxia." This condition happens when there is inadequate oxygen in the body to sustain normal bodily functions. Symptoms can range from lightheadedness and confusion to loss of consciousness and potential long-term brain damage.
Which describes oxygen content as Earth evolved over time?
As Earth evolved over time, oxygen content gradually increased due to the process of photosynthesis by early microorganisms. This led to the rise of oxygen levels in the atmosphere, eventually creating the oxygen-rich environment we have today.
Which of the options below best describes the following series of statements John Smith is a person. All people need to breathe oxygen. John Smith needs to breathe oxygen.?
causation
Is oxygen malleable or not?
Oxygen is a gas at room temperature and pressure, so it is not malleable. Malleability is a property that describes a material's ability to be hammered or rolled into thin sheets without breaking. Oxygen does not exhibit this property.
What best describes the difference between the formulas for nitrogen monoxide and nitrogen dioxide?
The formula for nitrogen monoxide is NO, where nitrogen and oxygen are bonded with a single bond. In contrast, the formula for nitrogen dioxide is NO2, where nitrogen and one oxygen atom are bonded with a double bond and another oxygen atom is bonded with a single bond.
What term best describes oxygen in photosynthesis?
Reactant
Describes a process that requires oxygen?
Aerobic
What word describes the absence of oxygen?
It is referred to as a vaccum, when there are no oxygen particles in a space, namely, outer space. Technology also exists to create an artificial vaccum by allowing the oxygen to escape from a bag, or jar, or whatever it is. dying
What describes the earths atmosphere?
mostly nitrogen with 21% oxygen
What o word describes the movement of oxygen with molecules?
ozone
What best describes the atmosphere?
mostly nitrogen with 21% oxygen
What describes blood flowing in an artery?
It is oxygen rich. Apex
What describes air you breathe?
When you breath air it is mostly nitogen and oxygen.
What best describes an asphyxiant?
chemicals that block the supply of oxygen to the body
Is the biogeochemical cycle that describes the movement of oxygen within and between it's three main reservoirs?
Yes, the oxygen cycle describes the movement of oxygen between its three main reservoirs: the atmosphere, biosphere, and lithosphere. Oxygen is produced primarily through photosynthesis in plants and algae, and consumed by living organisms during respiration and decomposition processes.
The basic unit that describes energy costs in terms of oxygen consumption is the?
Met.
What is a chemical property hardness ability to react with oxygen color or freezing point?
Hardness is a physical property that describes the ability of a substance to resist deformation. Ability to react with oxygen is a chemical property that describes how a substance interacts with oxygen. Color is a physical property that describes the visual appearance of a substance. Freezing point is a physical property that indicates the temperature at which a substance changes from a liquid to a solid.
