Civil liberties are personal guarantees and freedoms that the government cannot abridge, either by law or by judicial interpretation without due process.
Ciliophora. A subphylum of the Protozoa. The ciliates are a fairly homogeneous group of highly differentiated, unicellular organisms. Over 5000 species have been described, and many more surely exist but remain to be discovered. Typically, ciliates are larger than most other protozoans, ranging from 10 to 3000 micrometers (about 1/2500 to 1/8 in.).
Single-celled eukaryotes, which are organisms with cells that have a nucleus, often use cilia to move through liquid. This type of organism is surrounded by a cytoskeleton, made of protein filaments that allow the cell to hold its shape.
