Final answer:
The statement that competition and collaboration can be present at the same time is true. They coexist in biological systems and other contexts, influencing outcomes such as adaptation or exclusion among species, as well as social and economic changes, as seen in the market revolution. The correct option is:a) True
Step-by-step explanation:
The statement that competition and collaboration are often present at the same time is true. These two forces can coexist in biological systems as well as in social and economic contexts. For instance, in biological ecosystems, two species may compete for the same resources while also engaging in behaviors that are mutually beneficial, thereby displaying both competition and collaboration.
In the case of interspecific competition, two possible outcomes could be that one species outcompetes the other leading to the exclusion of the less competitive species, or the species may adapt by utilizing different resources, which allows for coexistence. In the context of symbiotic relationships, it is not necessary for two species to physically touch each other, as some symbiotic relationships, such as parasitism, can be non-physical. A relationship between humans and the protists that cause malaria is an example of parasitism, not commensalism, since the protist benefits at the expense of the human host.
In reference to the market revolution, it is true that it brought many social and economic changes to the United States, including shifts in labor structures, the rise of factories, and the expansion of domestic markets. The correct option is:a) True
