Answer:
c. number and variety of organisms vs. changing environment
Explanation:
In an ecosystem populations are in dynamic equilibrium with each other, for when a population decreases the population of its predators also decreases, because the various populations are dependent on each other for survival. What we can understand from this is that the diminishing population of a species has caused a change in the environment, making that environment unsuitable for the predator population.
In other words, dynamic equilibrium occurs when the size of a population of a species varies with changes in the environment in which they live. For this reason we can state that the number and variety of organisms vs. changing environment best indicates the dynamic balance of an ecosystem.
DNA helicase - unzips the DNA double helix
DNA Polymerase - edits genes to ensure there are no errors, a 'proofreading system'.
DNA ligase - joins all the DNA together
Yes they can Only eukaryotes form multicellular organisms consisting of many kinds of tissue made up of different cell types
