- 1. Most land animals with exoskeletons are smaller than the volume of a mouse, and most vertebrates are larger than a mouse (marine invertebrates can be somewhat bigger). What keeps an insect with an exoskeleton from being as big as a horse. 2. Bone gains its rigidity from brick‑hard deposits amidst living cells. Yet we cannot build a large stone skyscraper from a small stone house without breaking the house apart. Yet our bones grow from small hard bones to large hard bones without ever breaking apart into soft vulnerable tissue. How is that accomplished? 3. Why will an increase in the strength of a stimulus cause an increase in the force of contraction in a whole muscle but not in a single muscle fiber?arrow_forward13 of 20 Which statement about the endoskeletons of vertebrates is true? Only one bone is required to form a joint. The muscles are attached to a nonliving support structure. The rib bones are part of the appendicular skeleton. They allow the animal to expand without molting. They consist of bone, only.arrow_forwardWhich of the following are aspects of the structure of skeletal muscle? Select all that apply. The muscle fibers are parallel to one another and have a striated appearance. They have more mitochondria than other types of muscle cells. Each fiber contains many units of contraction and protein filaments. Cells are branched or unbranched with single nuclei. It consists of cylindrical cells called muscle fibers that have multiple nuclei.arrow_forward
