Adaptations usually occur because a gene mutates or changes by accident! Some mutations can help an animal or plant survive better than others in the species without the mutation. For example, imagine a bird species. One day a bird is born with a beak that is longer than the beak of other birds in the species.
Answer:
When the energy is absorbed in a chemical reaction, we can say that this is an endothermic reaction.
Explanation:
An endothermic reaction is a chemical reaction that absorbs energy instead of releasing energy, like exothermic reactions.
To be considered an endothermic reaction, the chemical reaction must have a low energy reagent and for that reason, they need to absorb energy so that there is a rearrangement of the reactant molecules, forming products with high energy.
The barnacles are only able to attach them selfs to surfaces in the water. Since the surface is limited, barnacles are attaching themselves to the other barnacles, crowding the rock. The muscles were not able to grow or attach themselves off the surface of the rock. Same thing with the mussels that are growing on the rock. So not only barnacles are crowding the rock, but Mussels as well are crowding the rock.
