Description: This video covers the topic of cell size. It is important for cells to stay small because they need to maintain a high surface area to volume ratio. This allows cells to diffuse or transport materials into and out of the cell most efficiently.

Biology

Learning is a true passion of mine, and I am committed to be a life-long learner.  I firmly believe that there is always more to learn.  Learning is fundamental to development, and being open to try new things is the key to building new skills and gaining more knowledge.

I personalize learning and make content relevant to everyday life so that learning experiences are memorable and engaging!

This video covers what ecology is, as well as some topics that will be covered in future videos. Topics like biogeochemical cycles, levels of organization, energy pyramids and much more were briefly introduced.

Biology Briefs with Bryan- Introduction to Ecology

This video discusses artificial selection, which is a process of selecting desired traits with human influence. It discusses the benefits and drawbacks of the process.

Biology Briefs with Bryan- Artificial Selection

This video discusses vestigial and analogous structures, and their relevance to evolution. It gives an overview and examples of each.

Biology Briefs with Bryan- Vestigial and Analogous Structures

This video discusses one of the main pieces of evidence for evolution: homologous structures. Homologous structures are structures with the same or similar structure, but different function, and they support common ancestory.

Biology Briefs with Bryan- Evidence for Evolution- Homologous Structures

This video discusses another piece of evidence for evolution: embryology. It also discusses how homologous structures can be seen during early embryo development that will not be seen in fully developed organisms of different species.

Biology Briefs with Bryan- Evidence for Evolution- Embryology

This video discusses how the genetic code provides evidence for evolution. It also references phylogenetic trees, and how they support the concept of common ancestors.

Biology Briefs with Bryan- Evidence for Evolution- Genetic Code

This video discusses one of the more referenced pieces of evidence for evolution: the fossil record. Fossil provide scientists with physical evidence of how species have changed over time.

Biology Briefs with Bryan- Evidence for Evolution- Fossil Record

This video focuses on coevolution, which is sometimes referred to as parallel evolutions. Coevolution involves simultaneous changes to two species that are in close proximity to one another.

Biology Briefs with Bryan- Coevolution

This video focuses on divergent evolution. Divergent evolution occurs when related species become increasing different, and eventually lead to the inability to bred with one another.

Biology Briefs with Bryan- Divergent Evolution

This video highlights the type of evolution known as convergent evolution. It also discusses analogous structures, and demonstrates how sharks and dolphins are a good example of convergent evolution.

Biology Briefs with Bryan- Convergent Evolution 

This video provides an overview of the concept of natural selection. It discusses how individuals with the best traits survive long and reproduce, thus passing those traits to the next generation.

Biology Briefs with Bryan- Natural Selection

This video discusses the main ideas of evolution including evidence for evolution and the different types of evolution. It sets the stage for the several other topics within the field of evolution.
