Explore how cells form the basic unit of life, distinguish prokaryotic and eukaryotic types, and examine cell theory, size, surface-area-to-volume ratios, and teamwork implications.
Explore exocytosis and regulated secretion, where vesicles fuse with the plasma membrane to release hormones and digestive enzymes. See how the Golgi packages substances like insulin into vesicles for secretion.
Learn how the cell cycle coordinates DNA replication and cell division through interphase (g1, s, g2) and the mitotic phase, including mitosis and cytokinesis, with variations among cell types.
Explain how internal and external signals, including growth factors and hormones, regulate the cell cycle with cyclin-dependent kinases at G1, S, G2, and M checkpoints, balancing growth and apoptosis.
Explore sexual reproduction at the cellular level, where egg and sperm fuse to restore 46 chromosomes through meiosis, revealing alleles, homologous chromosomes, and genetic variation.
Describes how meiosis reduces chromosome number from diploid to haploid through two divisions, forming gametes with recombined genomes via crossing over, increasing offspring diversity.
Meiosis stages—prophase, metaphase, anaphase, and telophase—occur across two divisions that reduce chromosome number, with crossing over and sister chromatids separating to yield haploid gametes.
Explore how meiosis and mitosis differ: meiosis creates four haploid gametes via two divisions, while mitosis yields two identical diploid cells, with meiosis reducing chromosome number and promoting genetic variation.
Welcome to Part II of The General Biology Course series here on Udemy.
Biology is the study of life. In this course you will learn the concepts of General Biology from two complementary perspectives. First, you will gain the knowledge you need for academic and or professional development. Second, you will learn how Biology relates to day to day living.
The General Biology Series will allows you to Master the principles and concepts of biology at your own pace.
Learn about the hierarchy of life on Earth.
Learn how cells grow, produce energy, communicate, and keep living systems organized
Learn how DNA is produced by cells
Learn how cancers develop and spread through the body's tissues
Learn how parents pass genes to their children from generation to generation
Learn about technologies like cloning and the production of genetically modified organisms (GMOs)
Part 2 of the General Biology Series will allow you to master the principles of Cell Biology.
Learn about Cell Structure
Learn about cellular processes such as cell division
Learn about the processes such as transport and reproduction that cells use to survive
And much, much more
Learning the fundamentals of biology equips you with a working knowledge of how living systems survive. This basic understanding can prepare you for a future in many different professions ranging from medicine, dentistry, nursing and pharmacy to public health and epidemiology.
Suitable for learners of all ages, through this course of lecture videos, PowerPoint presentations and online activities you will improve your scientific literacy in Biology. You will become knowledgeable of the major themes, concepts, and theories in biology that are regularly tested on standardized exams such as the MCAT, PCAT, and DAT. In addition, you will be able to explain how Biology relates to the foods you eat, products you use, air you breathe, and your overall health.
At the end of this course, I hope that you will have the materials you need to meet your educational goals. Equally important, I also hope that this course will enhance your appreciation for the study of life on our planet.
