| microevolution |
Microevolution is the occurrence of small-scale changes in gene frequencies in a population over a few generations, also known as change at or below the species level. These changes may be due to several processes: mutation, gene flow, genetic drift, as well as natural selection. Population genetics is the branch of biology that provides the mathematical structure for the study of the process of microevolution. ...

The Nissan Micra is a car produced by Nissan. Its name in Japan is Nissan March. The original Micra, which carried the official Nissan codename "K10-series", was introduced in 1982 was intended to replace the Cherry as the company's competitor in the "supermini" segment, as the Cherry model itself had progressively become larger with each successive generation. ...

| micrographia |
Published September, 1664, Micrographia was an immediate best-seller. The book details the then twenty-eight year-old Robert Hooke's observations through various lenses. Hooke most famously describes a fly's eye and a plant cell (where he coined that term). Known for its spectacular copperplate engravings of the miniature world, particularly its fold-out plates of insects, the text itself reinforces the tremendous power of the new microscope. ...

| microgravity |
Weightlessness is the experience (by people and objects) during freefall, of having no apparent weight. This condition is also known as microgravity (see below). Weightlessness in common spacecrafts is not due to an increased distance to the earth; the acceleration due to gravity at an altitude of, say, 100 km is only 3% less than at the surface of the earth. ...

| microfilament |
Actin is a globular protein that polymerize helicaly forming actin filaments (or microfilaments), which like the other two components of the cellular cytoskeleton form a three-dimensional network inside an eukariotic cell. Actin filaments provide mechanical support for the cell, determine the cell shape, enable cell movements (through pseudopods); and participate in certain cell junctions, in cytoplasmic streaming and in contraction of the cell during cytokinesis. ...
