Lunar maria (plural form of the Latin word mare, which means sea) are
dark surfaces that can be found all over the moon (17% of the Moon is
covered in them) that have been created as a result of volcanic
eruptions. These areas are made up of basalt, and given that they seemed
almost waterlike, the astronomers in the distant past mistook them for
seas, whence their name comes.
When it comes to craters, their origin
is quite similar - volcanic eruptions created them. When lava starts
erupting from a volcano, it has to get out from somewhere - and thus
craters are created. If you are referring to lunar craters, however,
there are many speculations as to how they were created: due to volcanic
eruptions, meteoric impact, or glacier activity.

Explanation:
Protein becomes denatured and cease to perform the work if structural changes occur because protein is highly specific in its function. It is stated that the function of the protein is determined by its structure. The proteins are the product of the continuous process of replication, transcription, translation and post-translational modifications. The information stored in it highly specific.
Protein binds with other molecules and perform various physiological functions as it has specific complementary attachment sites, the alteration in the structure would not let it bind to the target and hence desired result will not come out.
This is true, both prokaryotes and eukaryotes have cell membranes.
