Prophase :)
The phrase "the spindles disappear" typically refers to a stage in cell division, particularly during mitosis or meiosis, when the spindle fibers that help separate chromosomes break down. This usually occurs during telophase, the final stage of cell division, when the chromosomes reach opposite poles of the cell, and the nuclear envelope begins to reform. The disappearance of the spindles signifies the end of the chromosome separation process.

The phrase nuclear power means one or both of two things. It can be a type of electricity that is generated by nuclear energy or it can be a nation that possesses nuclear weapons.
The phrase "melt into thin air" means to disappear completely and suddenly, as if evaporating or vanishing without a trace. It is often used to describe something that is intangible or fleeting.
The phrase "membranes are bifacial" refers to the structure of cellular membranes, which have two distinct faces or sides. These faces, the inner and outer layers of the membrane, have different compositions and functions, allowing the membrane to regulate the passage of molecules in and out of the cell.
Cowboys loved a colorful phrase! This was another made-up word. It meant to leave or disappear.
The phrase comes from Prospero's famous speech in The Tempest, as follows: "These our actors, as I foretold you, were all spirits and are melted into air, into thin air". It means to disappear without a trace.
The phrase, "fall out," is a military term; an order from a superior, to troops in formation at attention. It is also a term in nuclear warfare referring to the radioactive dust created by a nuclear explosion.
That is not an idiom. It means just what it says. You need a medical dictionary to look up medical conditions, not an idiom dictionary. I think by idiom, you may be asking what type of language is represented by the phrase "inflammation of nictitating membrane." That phrase is typical of medical or scientific terminology rather than common or lay language.
The pleura is a membrane that surrounds the lungs of mammals. Presumably, the phrase means that the surface of the pleura was found to be normal in an examination.
I believe the 'lipid-bilayer' refers to the membrane of a cell. A globular protein is something that takes on a roughly spherical shape. In cells proteins span the outside of a cell to the inside to help with the diffusion of molecules or especially ions that do not diffuse directly through the membrane.
It comes from the Cold War when it was said to remind people if a nuclear attack takes place to get under something ( duck) and cover.
