This gateway biology course provides a strong foundation in the principles of biology for students majoring in Natural Science, medical and healthcare fields. It is the second of a two-course sequence. Primary topics such as the history of life, body systems, and ecology are covered in this course.
This course was developed by Lumen Learning, with contributing work from Shelli Carter. The course is based on the OpenStax textbook Biology, supplemented with relevant materials from Khan Academy and videos from multiple sources. Original practice activities were authored by Shelli Carter and Lumen Learning in the development of this course.

Includes the study of the gross and microscopic structure of the systems of the human body with special emphasis on the relationship between structure and function. Integrates anatomy and physiology of cells, tissues, organs, the systems of the human body, and mechanisms responsible for homeostasis.

Paul Andersen differentiates between biotic and abiotic factors. He explains how both abiotic and biotic factors can affect organisms at the level of the cell, the population and even the ecosystem. The complexities of biofilms, predator-prey relationships, and food webs are given as illustrative examples.

Students investigate the bone structure of a turkey femur and then create their own prototype versions as if they are biomedical engineers designing bone transplants for a bird. The challenge is to mimic the size, shape, structure, mass and density of the real bone. Students begin by watching a TED Talk about printing a human kidney and reading a news article about 3D printing a replacement bone for an eagle. Then teams gather data—using calipers to get the exact turkey femur measurements—and determine the bone’s mass and density. They make to-scale sketches of the bone and then use modeling clay, plastic drinking straws and pipe cleaners to create 3D prototypes of the bone. Next, groups each cut and measure a turkey femur cross-section, which they draw in CAD software and then print on a 3D printer. Students reflect on the design/build process and the challenges encountered when making realistic bone replacements. A pre/post-quiz, worksheet and rubric are included. If no 3D printer, shorten the activity by just making the hand-generated replicate bones.

Paul Andersen explains how the cell cycle is used to create new cells. The creation of identical diploid daughter cells, through mitosis, is described. The creation of unique haploid daughter cells, through meiosis is also described.

Paul Andersen explains how cells duplicate through the process of cell division. Prokaryotic cells (like bacteria) duplicate through a process of binary fission. Eukaryotic cells (like you) duplicate body cells through mitosis and create sex cells through meiosis.
Students color-code a schematic of a cell and its cell membrane structures. …
Students color-code a schematic of a cell and its cell membrane structures. Then they complete the "Build-a-Membrane" activity found at http://learn.genetics.utah.edu. This reinforces their understanding of the structure and function of animal cells, and shows them the importance of being able to construct a tangible model of something that is otherwise difficult to see.

Students learn about the different structures that comprise cell membranes, fulfilling part of the Research and Revise stages of the legacy cycle. They view online animations of cell membrane dynamics (links provided). Then they observe three teacher demonstrations that illustrate diffusion and osmosis concepts, as well as the effect of movement through a semi-permeable membrane using Lugol's solution.

Paul Andersen explains how cells are selectively permeable with the help of their cell membrane. The main constituents of the cell membrane, including cholesterol, glycolipids, glycoproteins, phospholipids, and proteins are included. The fluid mosaic model is also illustrated. The cell wall in plants, bacteria, and fungi is also discussed.
