In a cladogram (a type of phylogenetic tree), clades are groups of related organisms. In the past, phylogenetic lists built clad
es using the idea of parsimony, that the pattern that uses the fewest evolutionary changes is the most likely to be correct. Today, with the use of computers and DNA sequences, the explanation that is thought to be the best is ___________ .
one with the fewest number of genetic differences in the nucleotide sequence.
Explanation:
A cladogram is a diagram capable of showing the relationships among different species and/or group of organisms. In a cladogram, the root indicates the common ancestor, while internal nodes represent the common ancestors of each group. In consequence, this diagram can be used to establish evolutionary relationships in which the start branch points represent common ancestors shared by the organisms found in the 'branches'. Nonetheless, the length of the branches in the cladogram does not represent evolutionary distances among groups. In recent years, cladograms based on DNA sequencing data have been combined with morphological data to establish evolutionary relationships among species.
When a hostname is configured through the Cisco CLI, some naming conventions must be follows. These naming conventions are as follows: 1- The name of the host must always begin with a letter 2- The name of the host cannot contain any spaces 3- The length of the hostname should always be less than 64 letters
<span>The hypothesis was that the cause of stomach-ulcers
is Helicobacter pylori and not spicy food. Marshall and Warren were able to
prove that the main cause of peptic ulcers was the bacterium Helicobacter
pylori instead of the spicy foods and stress, which physicians believed were
the main causes of peptic ulcers at the time.</span>
Arteries are blood vessels responsible for carrying oxygen-rich blood away from the heart to the body. Veins are blood vessels that carry blood low in oxygen from the body back to the heart for reoxygenation. Arteries and veins are two of the body's main type of blood vessels.
