Was oxygen higher in the past?
Yes, The oxygen content in the atmosphere was higher in the past, particularly in the carboniferous period.
Why do you need more oxygen at lower temperatures?
You Don't. You need higher amounts of Oxygen at higher temperatures.
What happen when higher energy ultraviolet radiations act on the oxygen at the higher level of the atmosphere?
when higher energy ultraviolet radiation act on the oxygen at the higher level of the atmosphere, they destroying many molecules of atmosphere.
What is theoretical oxygen demand?
The calculated amount of oxygen required to oxidized a compound to its final oxidation products . The organic matter of sewage is mainly composed of carbohydrats , protein, fats,and products of their decomposition . If the chemical formulaeof the organic matter are called as theoretical oxygen demand can be calculatd.
Does chlorine or oxygen has higher boiling point?
Chlorine has higher boiling point.
Why is oxygen consumption lower for walking than running?
Running causes the body to produce more blood to make oxygen to obtain stamina while walking is a low energy exercise and the build up of more blood to produce oxygen is slower.
Why does running make a person breathe faster?
Your body uses oxygen make energy, and muscles need energy to relax and contract, or flex. As you run, the demand for energy in your muscles increases, and so your lungs work harder to provide the oxygen your muscles are begging for. The result of higher demand for oxygen is faster deeper breaths.
Why do an athlete breathe faster and deeper after running?
you need to breath in order for ur blood flow and ur blood has to flow to the heart wen ur running ur heart is going fast cuz it needs the blood to flow faster so u can keep going and wen ur done running ur blood is going soo fast you need to breath fast
Is more or less blood being pumped from the heart after running?
More. Your heart is responding to the body's increased demand for oxygen.
What is a biological oxygen demand?
A biological oxygen demand is another term for a biochemical oxygen demand - the amount of oxygen needed by aerobic microorganisms to decompose all the organic matter in a sample of water - used as a measure of pollution.
The aerobic refers to the usage of?
Aerobic refers to the usage of oxygen. Popular forms of exercises also known as aerobic exercise that use a large amount of oxygen include running, walking, stepping, and spinning.
What is the different between biochemical oxygen demand and biological oxygen demand?
Oxygen Demand -The amount of oxygen require to oxidize an organic materialBiochemical (Biological) Oxygen Demand (BOD) -The amount of oxygen required to oxidized any organic matter present in the water by microbes present in the water. Usually representin the easily "digestible" organics.Chemical Oxygen Demand (CO) - The amount of oxidants experessed as oxygen required to consume all organics in a water sampleTotal Oxygen Demand (TOD) the sum of COD and BODBiological Oxygen demand is the oxygen required to oxidized only organic matter by micro organisms (it is basically a prototype of actual process happening in treatment plant) while chemical oxygen demand is the oxygen consumed to oxidize all organic and inorganic matter and it employ chemicals to do this process that why it is way more fast then BOD experiment .
Why is there a demand for chemical oxygen?
There is a very large demand for chemical oxygen. Chemical oxygen is very sought after because it can be used to determine when water is contaminated with pollutants.
What is mean chemical oxygen demand-?
The mean oxygen demand is the test done to indirectly determine the amount of organic compounds present in a water sample.
What kind of exercise creates an oxygen deficit?
Aerobic exercise requires oxygen, anaerobic exercise does not. Aerobic exercises include walking, running, swimming, and jumping rope.
What is it called when you demand oxygen to muscles?
A yawn
What is Decreased by the breakdown of organic wastes?
Dissolved Oxygen
