What are two types of a behavioral adaptation

instinctual and learned

Explanation:

All creatures need abilities to survive in the wilderness, because of this all creatures have a base instinct, or instinctual adaptation. Some creatures may have learned adaptations from being taught. For example, an instinctual adaptation would be a cat hissing in defense, or a dog barking or growling when it feels intimidated. A learned adaptation may be a dog learning to sit or roll over in exchange for treats. Hope this helps!

2h2o2--> 2h2o + o2

this reaction is of the spontaneous decomposition of hydrogen peroxide down into water and oxygen.

add 2 molecules of hydrogen peroxide and 2 molecules of water. since oxygen is naturally diatomic, the total number of atoms of each element is now the same on both sides of the equation so it is balanced.

this may not be entirely correct but let me know.

"the periodic table is arranged in order of atomic number."
