Coral reefs can be defined as underwater ecosystems, characterized by coral (marine invertebrates) skeletons. Coral reefs can survive only in clean and clear water. Pollutants and sediments smother the coral reefs, reduce water quality, and enhance the growth of damaging algae.
Pollution also makes coral reefs to become susceptible for disease, which impede growth and reproduction of corals, and cause damage to coral reefs.
Thus, the given statement is false as coral reefs are affected by pollution.
Ionic bonds are between metals and are permanent and very strong. They could hardly be called an attraction. This happens when one atom steals another atoms electron. Covalent bonds are strong but occurs between two different atoms they are also permanent to in this bond they share electrons and not take away. Hydrogen bonds are temporary and occur between molecules that have hydrogen and molecules that have elements like oxygen which become attracted to the hydrogen. These are weak but when they build up they can become very strong.
