Answer:
D
Explanation:
Everything in there pollutes the environment.
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.

The answer is genetic drift (bottleneck effect)
<span>There are 4 basic mechanisms of evolution - mutation, genetic drift, natural selection, and gene flow (migration). Genetic drift is a change in the frequency of alleles in a population as a result of random sampling of organisms. One of the examples of genetic drift is the bottleneck event. </span>The bottleneck event means drastic reduction of the population size because of environment changes. The consequence of this is the reduction of genetic variation. This is what happened to the population of worms after tree falling.
Answer: Cells are the basic building blocks of all living things. Cells form structures to create tissue that makes up our bodies, plants, and animals.
