QUESTION 2
2. Identify whether the following statements are true or false.
2.1 False - A structure is a design that is created in a particular way to give shape to an object or an
organism. The statement contradicts the definition of a structure, which implies a specific,
purposeful arrangement of parts (NST1501, Study Guide. Page 5) (NST1501, 501. Page 4).
2.2 False - The skeleton is the most important frame structure for all vertebrates. The text explicitly
states that a key characteristic of chordates, which includes vertebrates, is having a brain and spinal
cord, a notochord (which supports the back), and other features, emphasizing the skeleton's crucial
role (NST1501, Study Guide. Page 43) (NST1501, 501. Page 33).
2.3 False - The key function of skeletons is to support the muscles and then protect the organs. The
text highlights that the skeleton provides a frame for the body, which supports muscles for
movement, and also protects vital internal organs (NST1501, Study Guide. Page 5) (NST1501, 501.
Page 4).
2.4 True - All vertebrates have a frame structure called a skeleton. The text confirms that a defining
characteristic of vertebrates (which are a major group within the phylum Chordata) is an internal
skeleton (NST1501, Study Guide. Page 43) (NST1501, 501. Page 33).
2.5 True - One way to strengthen materials is by changing the shape of the material. This concept is
part of the principles of structures and strengthening materials, as discussed in the context of natural
sciences and technology (NST1501, Study Guide. Page 5) (NST1501, 501. Page 4).
