Fungi are a highly diverse…mes in hive-196037 • 25 days 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 • 28 days 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 • 29 days 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 • last monthEvolutionary 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 • last monthEvolutionary 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 • last monthEvolutionary 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 • last monthEvolutionary 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 • last monthGenetics: 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 • 3 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 • 3 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 • 3 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 • 3 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…mes in hive-196037 • 3 months agoCell Cycle: Mitosis, Meiosis, and Binary FissionIn this video, I explain the cell cycle, the series of events a cell undergoes to divide into two (or four) daughter cells. In eukaryotic cells (such as animal and plant cells), there are two main…mes in hive-196037 • 3 months agoCell Communication via Autocrine, Paracrine, Juxtacrine, and Hormone SignalingIn this video I go over cell signaling which is the ability of cells to communicate with its environment, other cells, or with itself. Signals can be non-chemical such as light, electrical impulses…mes in hive-196037 • 4 months agoCell Structure and Organelles of Animal and Plant CellsIn this video I go over the typical cell structures of animal and plant cells as well as the many organelles that comprise them. Both cells contain a nucleus with most of the organism's genome…monirrohan in biology • 4 months agoBiology and Life Cycle || Detailed description of the gypsy moth's life cycle: egg, larva (caterpillar), pupa, and adult stages.There are four primary stages in the existence pattern of the wanderer moth (Lymantria dispar): the egg, hatchling (caterpillar), pupa, and grown-up.
