I believe that you are supposed to notice that the striations in the contracted muscle fibers are much closer together than the striations in the uncontracted muscle. Therefore, it would appear that somehow the striated parts of the muscle are being pulled closer together somehow. Glycerinated muscle retains the organized structural array of myosin thick filaments and actin thin filaments, actin associated proteins like troponin and tropomyosin which regulate contraction, and the functional capacity for contraction.

Plants are autotrophs because they carry out photosynthesis and produce food for themselves.
<span>Fungi does not contain chlorophyll or carry out photosynthesis, which is why you can find a lot of fungi in dark places. Fungi takes its nutrients from dead organic matter, which is why you would find fungi on rotten fruits and dead animals.</span>
