Answer the following question given this paragraph: Each muscle in the body is made up of cells called muscle fibers. Muscle fibers are long, thin cells that can do something that other cells cannot dothey are able to get shorter. Shortening of muscle fibers is called contraction . Muscle fibers can contract because they are made of proteins, called actin and myosin, that form long filaments (or fibers). When muscles contract, these protein filaments slide or glide past one another, shortening the length of the cell. When your muscles relax, the length extends back to the previous position. Nearly all movement in the body is the result of muscle contraction. Q: Shortening of muscle fibers is called what?' Choices: - diffusion - diffusion - shrinking - contraction A:
contraction

*Question*
Answer the following question given this paragraph: Living chordates are mainly vertebrates. In vertebrates, the notochord develops into a backbone, or vertebral column, after the embryonic stage. A small percentage of chordates are invertebrates. Their notochord never develops into a backbone. Invertebrate chordates include tunicates and lancelets. Both groups of animals are small and relatively primitive. They are probably similar to the earliest chordates that evolved more than 500 million years ago. Q: During the embryonic stage of vertebrates, the notochord develops into what? Choices: - rib cage - umbilical cord - brain stem - backbone A:
**Answer**
backbone

A: quantum numbers
