What else can I help you with?
Hydrogen bonding occurs in molecules where hydrogen is bonded to what elements fluorine carbon oxygen nitrogen hydrogen boron?
the hydrogen bonding is possible in oxygen, nitrogen,and fluorine
Most of the atmospheric oxygen occurs as a result of photosynthesis From which of the following molecules is the oxygen derived?
The oxygen in photosynthesis is derived from water.
What if intrapulmonary pressure is equal to atmospheric pressure?
When intrapulmonary pressure is equal to atmospheric pressure, air flow into and out of the lungs is temporarily suspended. This occurs at the end of inhalation and exhalation when the lungs reach equilibrium with the atmosphere.
What is the chemical formula of nitrogen in the air?
Elemental nitrogen in the air occurs in diatomic molecules and therefore has the formula N2.
In boiling water water molecules move apart and escape in the form of water vapor The process is called?
evaporation
Where oxygen and CO exchange places?
Oxygen and carbon dioxide exchange places through the process of gas exchange in the lungs during respiration. Oxygen from inhaled air diffuses into the bloodstream in exchange for carbon dioxide, which is then exhaled out of the body. This exchange occurs in the alveoli, small air sacs in the lungs where the transfer of gases takes place.
Will a chemical reaction in different molecules trade positions with exchange reaction?
No, a chemical reaction involving different molecules does not involve a direct exchange of atoms or positions between the molecules. Each molecule in a reaction follows its specific reaction pathway based on the reactivity and bonding preferences of the atoms within it.
What is the elastic unit of the respiratory system where gas exchange occurs?
Alveoli is where gas exchange occurs.
What part of the lung do oxygen molecules diffuse across into the bloodstream?
Oxygen molecules diffuse across the alveolar membrane in the lungs into the bloodstream. This is where gas exchange occurs, with oxygen moving from the alveoli into capillaries surrounding the alveoli.
Which of the nucleotides occurs in DNA molecules but not in RNA molecules?
Thymine is a nucleotide that occurs in DNA molecules but not in RNA molecules. In RNA, thymine is replaced by uracil.
A basement membrane occurs between?
a basement membrane occurs between the epithelial tissue and the connective tissue
Does exchange of gases occurs in nasal cavity?
No, it occurs in the lungs.
Where does the acual exchange of gasoccur?
The actual exchange of gases occurs in the alveoli
What occurs the process of gas exchange?

What are the key differences between cation exchange chromatography and anion exchange chromatography?
Cation exchange chromatography separates molecules based on their positive charge, while anion exchange chromatography separates molecules based on their negative charge. The key difference lies in the type of charge that is used to separate the molecules.
What occurs during the process gas exchange?

Gas exchange occurs in the .?
Alveoli
