BIOL 121 - College Biology I
4 Credit: (3 lecture, 2 lab, 0 clinical) 5 Contact Hours: [Reading Level 3 and Writing Level 3 and Math Level 3 ]
This course (in conjunction with BIOL 122 ) provides students with an in-depth introduction to fundamental areas of biology. It is intended as the first part of a two-semester sequence designed for students planning to transfer to a four-year college or university with a major in the natural sciences. Students are not required to take BIOL 122 before enrolling in this course. This course emphasizes the scientific method, basic chemistry concepts, cellular structure, function, and metabolism, cellular reproduction and genetics, the diversity of microorganisms, and body systems. Laboratories introduce basic biological techniques and reinforce principles learned in lecture.
OFFERED: fall semesters
