Answer:
A.Earth's early atmosphere lacked oxygen, which multicellular organisms need to break apart food
Explanation:
One important feature that led to the development of multicellular organisms was the rise of oxygen-producing photosynthetic bacteria. Prior to this development, the unicellular organisms (anaerobes) then present on Earth obtained energy from inorganic fuels.
However, with the presence of oxygen in the atmosphere, a shift was observed as organisms that could obtain energy from the reduction of energy became predominant. This unicellular aerobes later paved way for the evolution of multicellular aerobes.
Answer:
The correct option is B. An economist might use this example to <u>define resource immobility.</u>
Explanation:
Resource immobility can be described as a resource that happens to be of no competitive advantage. The resource is easy to obtain but competitors do not consider using it.
For example, in the scenario discussed in the question above, a similar plant is available in another city but the unemployed people do not want to avail that facility. The workers might compete for working in the closed plant but there is no such competition to work in the plant that is out of state.
