Process of Electron Transport Chain (ETC), is a series of transferring from electron donors to their acceptors.  It basically means a transfer from high energy molecule to a low-energy molecule.  This process of extracting energy by transfer is classified as a chemical reaction and we see it is the path taken of cellular respiration (NADH) and FADH2) and in photosynthesis, NADPH.  It starts with an electron, NADH and FADH2, when the electron donors release a proton gradient and it creates an imbalance.  Think of it as a see-saw with one heavy person on one end and a lighter one on the other end.  The protons actually attempt to defuse back across this see-saw of a membrane and it releases energy during the cross over which we call Chemiosmosis.

Where is air almost completely humidified? in the lungs in the trachea in the alveoli in the nose?
motikmotik
None of the provided choices provide a completely correct answer. In fact, 75% of humidification takes place in the nose and mouth, with the rest taking place in the trachea. When you breath in, mucous membranes inside the nose and mouth release moisture to air. It is estimated that the average adult evaporates 200 to 300 ml of water per day during this process. The process is very efficient: while  breathing in through nose or mouth, the mucous membranes are cooled down.  During breathing out, this cooling effect causes condensation of some of the moisture in the air coming from the lungs, thereby moisturizing the mucous membranes

lesya [120]
The code for this procedure allows for imaging a patient twice.
A pulmonary perfusion imaging or pulmonary ventilation scan is used to check that how well air and blood are able to flow through your lungs. Pulmonary embolism is a condition in which two or more arteries are blocked by the blood clot in lungs and it is the fatal complication after the trauma.

[O.05]Read the paragraph below.
liubo4ka [24]

Answer: geosphere and biosphere

Explanation:

The geosphere is the part of the earth which lies below the earth crust. The biosphere is the sphere where all living beings survive.

According to the given situation, the ocean is interacting with the geosphere and biosphere. This is because of the fact that the earthquake emerged in the undersurface of the ocean is the part of the geosphere. The waves produced due to instability of the undersurface resulted in high speed waves. These waves resulted in drastic floods. The floods caused the destruction of the property of the coast, inland areas, plants and animals which came in contact with the flood. Hence, the biosphere was affected.

How is the static from CSMR used by cosmologists?
jenyasd209 [6]

The static from CSMR is used by cosmologists for ; estimating the age of the universe ( C )

Cosmologists are scientists that study the universe ( the age , evolution and possible expansion of the universe ).

A static in cosmology is the model indicating that the universe is infinite ( spatially and temporally ), this model simply suggest that the universe is neither expanding nor contrasting ), The first cosmologists suggested that the universe was static without a spatial curvature.

Therefore the static from CSMR is used by cosmologists to estimate the age of the universe since the static cosmology model of the universe was suggested by the first cosmologists.

Hence we can conclude that The static from CSMR is used by cosmologists for ; estimating the age of the universe
