Find out about the genetic blood disorder, sickle cell anemia, in this short narration. [0:59]
Biology 2e is designed to cover the scope and sequence requirements of a typical two-semester biology course for science majors. The text provides comprehensive coverage of foundational research and core biology concepts through an evolutionary lens. Biology includes rich features that engage students in scientific inquiry, highlight careers in the biological sciences, and offer everyday applications. The book also includes various types of practice and homework questions that help students understand—and apply—key concepts. The 2nd edition has been revised to incorporate clearer, more current, and more dynamic explanations, while maintaining the same organization as the first edition. Art and illustrations have been substantially improved, and the textbook features additional assessments and related resources.
By the end of this section, you will be able to do the following:
Describe how oxygen is bound to hemoglobin and transported to body tissues
Explain how carbon dioxide is transported from body tissues to the lungs
Describes how natural selection changes allele frequency.
A free CK-12 account is required to view all materials.
This lesson will identify the cause and effects of various blood disorders. [5:21]
A brief overview of Sickle cell anemia, a genetic disease that affects hemoglobin in the blood. [1:30]
This pathway provides an introduction to heredity and how the biological process of meiosis leads to genetic diversity. The foundational concepts of Mendelian genetics are also reviewed. For a deeper look at this topic, we recommend the pathways Meiosis and Sexual Reproduction, Mendel's Experiments and Heredity and Modern Understandings of Inheritance from the OpenStax textbook Biology for AP® Courses.
This pathway outlines the process of genetic engineering with a focus on gene cloning. This pathway also provides an introduction for the ABE lab series.
Psychology is designed to meet scope and sequence requirements for the single-semester introduction to psychology course. The book offers a comprehensive treatment of core concepts, grounded in both classic studies and current and emerging research. The text also includes coverage of the DSM-5 in examinations of psychological disorders. Psychology incorporates discussions that reflect the diversity within the discipline, as well as the diversity of cultures and communities across the globe.Senior Contributing AuthorsRose M.

By the end of this section, you will be able to:
Explain the basic principles of the theory of evolution by natural selection
Describe the differences between genotype and phenotype
Discuss how gene-environment interactions are critical for expression of physical and psychological characteristics
This scrollable interactive explores the different roles that proteins can play in the cell. Categories of proteins covered include transmembrane proteins, proteins that make up molecular machines like cilia and ribosomes, and enzymes. The four levels of protein structure are also discussed.
WebMD Health offers a detailed overview of sickle cell disease, a severe blood disorder. Content includes a focus on this disease's causes, symptoms, and treatments, as well as information on how the disease progresses and when to call a doctor.
Sickle cell disease is an inherited blood disorder. Learn what it is and how it is passed on, what sickle cell crisis is and its cause, the signs and symptoms of sickle cell disease, how it is treated, tips for traveling if you have it, and how to manage the disease and care for oneself.
