Answer:
Since sea urchins are picky, they are used as indicator organisms in public aquariums to determine if the system is functioning properly. This is because they are very "picky" about water quality. If the water is contaminated, the sea urchins will be the first to show signs of stress, spines laying down or falling off. Do use an aquarium filter and do clean up the day after feeding. Any metal exposed to the seawater will corrode and poison the tank. A dying sea urchin will often spawn out and rot out, causing the others in the tank to spawn and die as welll.
Explanation:
Answer: Muscle fibers in bundles or fascicles.
Explanation:
Skeletal striated muscle is involved in dense unshaped connective tissue, the Epimysium. From the epimysium depart fine septa of connective tissue to the muscle, separating the bundles and constituting the perimysium, carrying blood vessels and lymphatics and nerves. Every muscle cell is involved in the basal lamina, reticular fibers and a small amount of connective tissue, which form the endomysium. It anchors muscle fibers between them and contains blood capillaries and axons.
