From Binet's work the IQ scale called the Binet Scale, (and later the Simon-Binet Scale) was developed. Sometime later, intelligence quotient, or IQ, entered our vocabulary.
Tuberculosis (TB) is an infectious disease that usually attacks the lungs, but can attack almost any part of the body. Tuberculosis is spread from person to person through the air. When a person with TB in their lungs or throat coughs, laughs, sneezes, sings, or even talks, the germs that cause TB may spread through the air.
However, beware for not everything that moves is motile! Under the microscope, motile bacteria seem to move in a purposeful way, though they may frequently change direction. However, even dead cells, such as those in this video, move.ost motile bacteria move by the use of flagella, rigid structures 20 nm in diameter and 15-20 Âµm long which protrude from the cell surface, e.g. the Chromatium cells in the video.
