A sample from this course

One topic, as StudyPath teaches it.

The structure of the cell and nucleus, important cell processes and elementary genetics.

This topic combines three foundations of biology: how cells are built, how the nucleus controls heredity, and how key cell processes support life. For the exam, you must clearly distinguish cell parts and their functions, explain major processes such as transport and cell division, and relate genes, chromosomes, and inheritance at an elementary level.
