Explanation: Vestigial structures are an anatomical feature or behavior that no longer seem to have any purpose in the present form of an organism in the given species. Usually, they are often parts of the body that used to preform important functions in earlier forms of the organism.
The body parts which are present in reduced form in the body and have lost their function in the body because of evolution are called <u>vestigial organs</u>.
Explanation:
The vestigial or rudimentary organs are the remnants of the structures or organs which might have been large and functional in the ancestors, or the organisms from which the present-day organisms have evolved. These vestigial organs are often undersized, degenerated and non-functional.
1.Examples of vestigial organs in humans ( Figure 1)
Vermiform Appendix- the human appendix is the remnant of the caecum which is large and functional in herbivorous mammals like cows and buffaloes. In these animals, it helps in digestion.
Caudal vertebrae - Also known as coccyx or tail bone, the caudal vertebrae is prominent among our close relatives like monkeys, in which this forms a functional tail.
2. Examples of vestigial organs in other animals (Figure 2)
Hind-limbs in Python- The python has no use of limbs so these structures have been diminished in them and are present in only rudimentary form.
The physical medical record belongs to the physician who created and the facility in which the record was created. The information gathered within the original medical record is owned by the patient. That is why patients are allowed a COPY of their medical record, but not the original document.
Over time the pond accumulates nutrients. This enrichment process is called eutrophication. The addition of nutrients stimulates the growth of aquatic life. These organisms live and grow and die
