Veins carry deoxygenated blood from the body to the heart so it can be sent to the lungs, pulmonary veins takes oxygenated blood from the lungs to the heart.
Sympatric speciation is the evolution of a new species from a surviving ancestral species while both continue to inhabit the same geographic region. In evolutionary biology and biogeography, sympatric and sympatry are terms referring to organisms whose ranges overlap so that they occur together at least in some places.
Answer: The species are poorly related to each other.
Darwin gave information for evolution as "descent with modifications" it involves a process in which species change and gives rise to a new species over generations. He proposed that the evolutionary history of life forms a branching tree with many level as a new species evolve. All species can be traced back to a common ancestor. Each newly evolved species will have one or more characteristics in common as that of the old species.
In species with no common ancestor will not have any similar characteristic in common such species cannot be evolutionary linked and cannot be placed and linked in an phylogenetic tree.
Well predation is the act of being similar and parasitism is when one thing takes advantage of something and harms it
I believe using gel electrophoresis to separate and identify plasmids and short linear pieces of DNA would be important if one is making a recombinant plasmid and has to verify that he/she has been successful. Gel electrophoresis is a technique that is used to separate mixtures of DNA, RNA, or proteins according to molecular size. The molecules being separated are pushed by an electrical field through a gel that contains small pores.
