Well, an endoskeleton is an internal skeleton, like humans have.
Pro: Bones do not get broke as easily, since they are inside of the body. Bones that break also heal more quickly in an endoskeleton, since they have tissue and blood surrounding it and transferring nutrients.
Con: The flesh can get easily damaged. There is no shedding with endoskeletons, so a new skeleton cannot be grown in the event of an injury.
Answer:
3 North poles and 3 South poles
Explanation:
A magnet is a piece of object that produces a magnetic field outside itself. A magnet has a north pole and a south pole. Similar poles repel each other, while opposite poles attract each other.
If a magnet of 10cm is broken into 3 pieces, we will have 3 pieces of magnet. Breaking a magnet does not destroy the properties of the magnet. Rather, each piece becomes a full magnet with both north and south poles.
Breaking a 10cm magnet will give us 3 magnets with 3 north and 3 south poles with equal pole strength.
Conservationists occasionally light forests on fire to control wild fires. By occasionally burning material (like leaves, branches, etc), those materials cannot build up and cause large and uncontrollable fires later.
A constant in an experiment is <u>B. </u><span><u>the quantity that must remain the same</u>. If it is constant, it doesn't change, so it cannot be variable. D makes no sense.
