Is the basal taxon in a phylogenetic tree the same as the outgroup? What is cladistics? Identify the normal structure and function of the gastroenterology. Describe the structure and function of nucleic acids in living organisms. Can you explain how 6! is the answer to this question: Which ex...
Is the basal taxon in a phylogenetic tree the same as the outgroup? Why do human sex cells only contain a total of 23 chromosomes each versus 46 like other human cells? What would happen if they contained a total of 46 chromosomes each?
They are characterized by the presence of three to five anterior flagella, hydrogenosomes –hydrogen-producing organelles corresponding to anaerobic versions of mitochondria [2], a parabasal body (a large Golgi), and a complex cytoskeleton. A few species have been isolated from environmental samples...
Sarcopterygii (; from Greek: σάρξ sarx 'flesh' and πτέρυξ pteryx 'fin') — sometimes considered synonymous with Crossopterygii ("fringe-finned fish", from Greek κροσσός krossos 'fringe') — is a taxon (traditionally a class or subclass) of the bony fishes ...
The other papers in this special issue deal with fungal speciation in Ascomycota, Dothideomycetes, Basidiomycota, basal fungi, lichen-forming fungi, plant pathogenic fungi, and yeasts. This is a preview of subscription content, log in via an institution to check access. Similar content being ...
The basal body is characterized by microtubule triplets, a pair of centrioles near the rostrum, as well as parabasal fibers linking the basal body to the Golgi complexes. Compared to Trichomonas species, Trichonympha species have a pointed anterior and broad, rounded posterior (there are no ...
Our 3D computer models of a basal dinosaur and bird, showing methods and key differences in body shape. The numbers at the bottom are museum specimen numbers. At about the moment I’m posting this, our Nature paper (our more formal page here, and theactual article here) embargo is ending...
Taxonomy: Belonging to the Order Heteroptera, True Bugs showcase two pairs of wings with an outer pair divided into a leathery basal part and a membranous apical part. Tarsi: Their legs consist of three segments, called tarsi, suited for various functions such as swimming, jumping, or holding...
mobile, do not feed, have a thicker basal layer, and have an external cortical layer with large lipid droplets. They also do not have stylet, esophagus, and esophageal glands. The tail is sub-cylindrical, with a digitate terminus and are well adapted to be carried by the insect vector ...
Basal Angiosperms The basal angiosperms, magnoliids and their relatives, were once classified as dicots, due to the presence of two seed leaves and apparent similarities with dicots. However, genetic analysis shows that monocots are more closely related to the group now ...
