What else can I help you with?
Which was least likely to have been a component of earths atmosphere before life began?
Oxygen was least likely to have been a component of Earth's atmosphere before life began. It was initially scarce, and the atmosphere was primarily made up of gases such as methane, ammonia, water vapor, and carbon dioxide. Oxygen started to accumulate in the atmosphere following the emergence of photosynthetic organisms.
Does earth have helium?
Yes, helium is present in the Earth's atmosphere, although it is relatively scarce compared to other gases like nitrogen and oxygen. Helium is not produced on Earth and is primarily sourced from underground reserves through natural gas extraction.
Is oxygen 17 and oxygen 18 the same isotopes of oxygen?
No, oxygen-17 and oxygen-18 are different isotopes of oxygen. They differ in the number of neutrons each atom contains. Oxygen-17 has 8 protons and 9 neutrons while oxygen-18 has 8 protons and 10 neutrons.
4litre of oxygen is how much percentage of oxygen?
4 liters of oxygen is 100% oxygen because the volume is entirely filled with oxygen.
How does an oxygen conserving device conserve oxygen?
An oxygen conserving device delivers oxygen to the user only when they inhale, as opposed to continuously flowing oxygen. This helps to reduce the amount of oxygen wasted during exhalation and increases the efficiency of oxygen delivery.
When oxygen is scarce cellular pyruvic acid will be converted to?
When oxygen is scarce, cellular pyruvic acid will be converted to lactic acid through a process called lactic acid fermentation. This process helps regenerate NAD+ to keep glycolysis running in the absence of oxygen.
What is a reaction that does not use oxygen?
Anaerobic respiration is a process that does not use oxygen. It involves the breakdown of glucose to produce energy without the need for oxygen as the final electron acceptor. This process typically occurs in environments where oxygen is scarce.
How does heat affect the air around us?
It makes oxygen scarce just as it does to water. The humidity becomes higher.
Where does the anaerobic pathway occur?
The anaerobic pathway occurs in the cytoplasm of cells. It is a metabolic process that does not require oxygen and is used to produce energy, typically in situations where oxygen is scarce or during intense exercise.
What part of speech is scarce?
Scarce is an adjective.
A sentence with the word scarce?
I can give you several sentences.Money is scarce in my house.We need to conserve scarce resources.Make yourself scarce!
Why all goods and services are scarce?
All resources are scarce.
Can Venus support air?
If by "air," you mean oxygen, then no. Venus's atmosphere is made up mostly of carbon dioxide and nitrogen. Other chemical compounds are scarce.
What product can remove scarce?
Proactive scarce removing.
Why goods and services are scarce?
All resources are scarce.
Why time as a resource is scarce?
Because it is important
What does anaerbic mean?
Anaerobic refers to a type of cellular respiration that occurs in the absence of oxygen. This process typically produces lactic acid or ethanol as byproducts. It is often used by cells when oxygen is scarce or during high-intensity exercise.
