Animals are heterotrophs since they feed on other living organisms for energy and organic…mes in hive-196037 • 20 days agoAnimal Form and Function: Water and Salt BalanceIn this video I discuss how animals regulate their body fluid composition. Vertebrate animals have kidneys which filter out blood plasma and expel the waste as urine through the urethra. Some…mes in hive-196037 • 21 days agoAnimal Form and Function: Principles, Thermoregulation, and Energy ConsumptionIn this video I discuss the main principles that govern an animal's form and interactions with its environment. The cells in animals are bathed in interstitial fluid, which describe the animal's…mes in hive-196037 • 22 days agoPlant Responses: Hormones, Ripening, and PhototropismIn this video I have uploaded a rare 2000 interview of John Hutchison on the Elaine Smith Show titled: Discoveries in Zero Point Energy: - Power for Nothing. John discusses his work on the Hutchison…mes in hive-196037 • last monthPlant Nutrition and Transport: Hydroponics, Osmosis, and TranslocationIn this video I explore the mechanisms by which plants transport water and nutrients. Essential nutrients for plant growth and reproduction are identified through controlled hydroponic experiments…mes in hive-196037 • last monthPlant Body: Roots, Leaves, Flowers, Reproduction, Xylem and PhloemIn this video I go over how plants are divided into root and shoot systems. The root system anchors the plant and absorbs water and nutrients, while the shoot system includes stems, leaves for…mes in hive-196037 • last monthMainstream Overview of Viruses, Virology, and VaccinesIn this video I provide an overview of mainstream virology in terms of the theory of how viruses develop immunity and the various types of vaccines currently in production as well as future ones…mes in hive-196037 • 3 months agoFungi: Chitin, Yeasts, Molds, Mushrooms, and DecompositionIn this video, I discuss fungi, a group of eukaryotic organisms known for their role as decomposers and for containing the long-chain polymer chitin in their cell walls. Fungi are a highly diverse…mes in hive-196037 • 3 months agoPlant Diversity: Flowering Plants, Gymnosperms, Bryophytes, PollinationIn this video I discuss the wide variety of plants, which are mainly eukaryotes that obtain energy from the Sun via photosynthesis. There are over 410,000 known species of land plants and about…mes in hive-196037 • 3 months agoBiological Diversity: ProtistsIn this video I discuss protists, which are eukaryotic organisms that are not animals, plants, or fungi. Since this classification excludes other eukaryotes (organisms whose cell(s) have a…mes in hive-196037 • 3 months agoBiological Diversity: Bacteria, Archaea, and EutrophicationIn this video I go over bacteria and archaea which comprise two large and separate domains of prokaryotic microorganisms. Bacteria consist of one biological cell and were among the first life forms…mes in hive-196037 • 3 months agoEvolutionary Biology: History of Life, Mass Extinction Events, and DinosaursIn this video I go over the evolutionary history of life on Earth, which evolved from an universal common ancestor that lived about 3.5 billion years ago. There have been several mass extinction…mes in hive-196037 • 3 months agoEvolutionary Biology: Speciation, Reproductive Isolation, and HybridsIn this video, I explain speciation, the process by which one lineage splits into two independent lineages that evolve separately. For speciation to occur, reproductive isolation is required, which…mes in hive-196037 • 3 months agoEvolutionary Biology: Phylogenies, Homology, and TaxonomyIn this video I go over phylogenies, which represent the evolutionary history of a group of organisms or their genes. Phylogenetic trees are used to compare and group different species. All living…mes in hive-196037 • 3 months agoEvolutionary Processes: Natural Selection, Genetic Drift, Population BottlenecksIn this video I provide a quick overview of evolutionary biology, its history, and important processes that affect the genetic characteristics passed down to populations. Evolution is the change in…mes in hive-196037 • 4 months agoGenetics: Genes, Development, and EvolutionIn this video I review the 4 key stages of development of an organism: determination, differentiation, morphogenesis, and growth. I also discuss the role genes play in development or organisms and…mes in hive-196037 • 5 months agoBiotechnology: Molecular Cloning, CRISPR Gene Editing, and Genetically Modified OrganismsIn this video, I explore different types of modern biotechnology, including techniques that modify an organism's genome or create entirely new genes and life forms. One such technique, molecular or…mes in hive-196037 • 6 months agoGenomes: DNA Sequencing, Non-coding RNA, and Genetic MutationsIn this video, I explain the concept of genomes, which refers to the complete set of DNA in an organism, encompassing all of its genes. Contrast this with the transcriptome (the full set of RNA…mes in hive-196037 • 6 months agoDNA, RNA, Gene Expression, and the Central Dogma of Molecular BiologyIn this video, I explain the central dogma of molecular biology, which states that genetic information flows from DNA to RNA, and from RNA to protein, but never in reverse—from protein back to RNA…mes in hive-196037 • 6 months agoGenetics: Mendelian Inheritance, Dominant vs Recessive Genes, Autosomal vs Allosome ChromosomesIn this video I go over genetics, which is the study of inheritance, and specifically look at Mendelian inheritance in which genes and traits are passed on from parents to offspring. Genes are…
