cladogram
A cladogram will show the genus and family of organisms and the offshoots of these said organisms including those that no longer exist in the present day.
A blood clot, also called a thrombus, in the anterior interventricular branch causes sudden death. This branch supplies the majority of blood to the walls of both ventricles. The presence of a thrombus can block the bloodflow to heart muscle cells, causing instant death.
Is it what? Is it interesting? Is it useful? Is it purple? Is it... oh, never mind. Your "question" isn't actually a question - you need to add the word "What" at the beginning. Like this:"What is the branch of biology that deals with the grouping and naming of living things?"...But the answer to your non-question is "taxonomy".
Ethics is a branch of philosophy, not a branch of science (although scientists can still strive to be ethical).
A different derived trait
Cladogram-In a cladogram a, clade is an evolutionary branch that includes a common ancestor together with all its descendant species.
A phylogram is a whiole tree of organisms.The bottom has the first organism and each branch is another organism. A cladogram is like one line and a few other lines come up from that main line. Not as many organisms in a cladogram than a phlogram.
a Cladogram
A cladogram shows hypothesized phylogeny.
A cladogram is a diagram used in cladistics which shows relations among organisms. A cladogram is not however an evolutionary tree because it does not show how ancestors are related to descendants or how much they have changed; many evolutionary trees can be inferred from a single cladogram. A cladogram uses lines that branch off in different directions ending at groups of organisms. There are many shapes of cladograms but they all have lines that branch off from other lines. The lines can be traced back to where they branch off. These branching off points represent a hypothetical ancestor (not an actual entity) which would have the combined traits of the lines above it. This hypothetical ancestor might then provide clues about what to look for in an actual evolutionary ancestor. Although traditionally such cladograms were generated largely on the basis of morphological characters, DNA and RNA sequencing data and computational phylogenetics are now very commonly used in the generation of cladograms.
