The Five Types Of Species Interactions Competition Competition is a common interaction among many organisms.1. Competition is described as a relationship in which different individuals or populations attempt to use the same limited resource.s time passes, species may also coevolve, where a species may evolve certain adaptations that reduce the harm of or can benefit the relationship, such as chameleons which have evolved the ability to change color and blend into their environment, which they also use as a source of communication.
Jan 3, 2015. DNA replicates by the semiconservative model of replication. This model states that during replication of double stranded DNA, the two strands separate and each separate strand is then used as a template to make a new strand.
DNA is like the instruction manual for building and operating a cell. DNA replication needs to occur because existing cells divide to produce new cells. Each cell needs a full instruction manual to operate properly. So the DNA needs to be copied before cell division so that each new cell receives a full set of instructions! Here is a video which uses an animated tutorial to explain the process of DNA replication.
