It was enlarged significantly in 1949, adding a wing with additional classrooms, gymnasium, and auditorium. Grades 5 and 6 were moved to the adjacent White School in 1936, and the school was converted to an elementary school after the new high school opened in 1965.

On 2021, Stephen Quake guessed that the upper limit of the number of human cell types would be around 6000, based on a reasoning that "if biologists had discovered only 5% of cell types in the human body, then the upper limit of cell types to discover is somewhere around 6000 (i.e., 300/0.05)." [10] Other different efforts have used different ...
Parts-per-million cube of relative abundance by mass of elements in an average adult human body down to 1 ppm. About 99% of the mass of the human body is made up of six elements: oxygen, carbon, hydrogen, nitrogen, calcium, and phosphorus. Only about 0.85% is composed of another five elements: potassium, sulfur, sodium, chlorine, and magnesium ...
The cells of the body's surface form the outer layer of skin. Inside the body, epithelial cells form the lining of the mouth and alimentary canal and protect these organs. Epithelial tissues help in the elimination of waste. Epithelial tissues secrete enzymes and/or hormones in the form of glands. Some epithelial tissue perform secretory functions.
