What is the term for body parts that are reduced in size with no apparent function?
Body parts that are reduced in size with no apparent function would be vestigial limbs. Evolution could be at the root of the development of vestigial limbs. A good example would be a T-Rex with his tiny arms.
A structure in an organism that is reduced in size and function and that may have been complete and functional in the organisms ancestors?

Homologous structure that is greatly reduced in size is called?
A homologous structure that is greatly reduced in size is known as a vestigial structure. These structures are remnants of organs or body parts that had a function in ancestors but are no longer used in modern organisms. Examples include the human appendix and the hip bones in whales.
Why would a vestigial structure once it has been reduced to a certain size not disappear altogether?
With time, if an organ or structure is no longer needed, natural selection may reduce the size of the organ until it completely disappears from the species or is very reduced in size. It is suggested that some vestigial organs may remain in a reduced state because they have a minor function within the body.
A body part which is reduced in size and seems to have no function is called?
A body part that is reduced in size and seems to have no function is typically referred to as a vestigial organ or structure. These may be remnants of evolutionary adaptations that are no longer needed in current organisms. An example in humans is the appendix.
Homologous structure that is greatly reduced in size?
The pelvic bones in modern whales are an example of a homologous structure that has become greatly reduced in size. These bones are a remnant of the pelvis found in the common ancestor of whales and other mammals, but their size and function have been greatly reduced due to evolution and the adaptation of whales to an aquatic lifestyle.
A body part which is reduced in size and seems to have no function is called what?
That body part is often referred to as a vestigial structure. These are remnants of organs or structures that had a function in the organism's evolutionary past, but have reduced in size or lost their function over time. Examples include the human appendix and tailbone.
What body parts that reduce in size with no apparent function?
pineal gland
What homologous structure that is greatly reduced to size?
Vestigial Organs
What is an organelle how does its structure affect its function?
an organelle is a small cell structure that carries out a function within the cell. I believe that the function is determined by the shape and size of it because the organelle needs to be a certain size to carry out all of the functions that need to be preformed.
What is A body part which is reduced in size and seems to have no function is called?
Vestigial structures. Like the appendix in humans.
What does a vestigial structure mean?
Vestigiality describes homologous characters of organisms which have lost all or most of their original function in a species through evolution. These may take various forms such as anatomical structures, behaviors and biochemical pathways
