1. The advantages that flying insects have ober arthropods that cannot fly is that it’s very easy for them to move or transport theirself from a place to another. Another is that it allows them to occupy new ecological niches. Compared to these arthropods that cannot fly, it’s really easy for them to occupy them. Also, many insects are predators themselves and this gives them an advantage in predator-pray arm race. 2. The scientific name for an arthropod (insects, arachnids, and crustaceans) shedding their exoskeleton is called Ecdysis. First, the arthropod enters a state of inactivity while the exoskeleton separates from the epidermis beneath. Then the arthropod secretes a digestive fluid from the moulting glands to fill the space between the epidermis and the old cuticle (which the exoskeleton grew from). The digestive fluid remains inactive however, until the new cuticle starts to grow. In the meantime, the arthropod pushes the exoskeleton off by making small movements forward within the old exoskeleton, which splits down the back, the splitting usually caused by the arthropod increasing it's blood pressure, the split allowing the organism to emerge. The old cuticle is then digested by the fluids released earlier, leaving the new cuticle, from which the new exoskeleton will grow. 3. 4. From the given situation, that was not a good way to protect the oysters because some species of sea stars can regrow and might affect again the predation progress and let the problem aggravate. A better method to kill these sea stars is to take it away from the water and let it dry in the sun. This is really an effective way for them to die since fishes really need water to live.
