In de driedimensionale (3D) ruimte wijzen de vier covalente bindingen van koolstofatomen naar de hoeken van een regelmatige tetraëder. Het molecuul dat hieronder wordt weergegeven, is methaan ((CH_4)). Wanneer een koolstofatoom vier verschillende structuren heeft, kunnen er twee verschillende moleculen worden gevormd. Voorbeeld 2.
I have been doing some gardening recently and I suddenly realised that all plants have superficially identical non-woody roots of the same size from gigantic trees to small fruiting plants and vege…
What you’ll learn to do: Identify the stages of meiosis by picture and by description of major milestones; explain why meiosis involves two rounds of nuclear divisionWhat is the difference between mitosis and meiosis? We know that mitosis produces the somatic cells of the body like skin and muscle cells, and meiosis produces sex cells like eggs and sperm — let’s learn just how similar and different these processes are.
I'm aware that platelets don't contain a nucleus, but do contain mitochondria (so have mtDNA) and rough endoplasmic reticulum / Golgi. Since platelets require many important cell surface proteins (…
Learning OutcomesList the different levels of the taxonomic classification systemTaxonomy (which literally means “arrangement law”) is the science of classifying organisms to construct internationally shared classification systems with each organism placed into more and more inclusive groupings. This organization from larger to smaller, more specific categories is called a hierarchical system.
Het is dus duidelijk dat virussen niet leven. Maar toen mijn leraar virussen onderwees in de video (we doen dit semester "flip" leren), zoals hij het beschreef, leek het alsof de virussen reageerden...
