It'll be much cleaner for the environment.
Answer:
The correct answer is - Archaea or archaebacteria.
Explanation:
Archaea is the domain and the kingdom of the single-cell prokaryotic organisms as they lack a nucleus. These organisms are present in extreme habitats such as hot springs, high saline water. These organisms can live in extremely aggressive environments which makes it a uniqe characteristic of this organism.
In the given condition the organism that lives in hypersaline water is most likely a member of the Archaea domain or Archaebacteria kingdom as it is found in the hypersaline waters of Southeastern Australia and unicellular organisms.
The greater the amount of active transport carried out by a cell, the greater the amount of mitochondria would be found in the cell.
Active transport uses energy. Mitochondria undergoes aerobic respiration to release large amounts of energy. If the cell is found to be lacking in energy needed for active transport, the cell would adapt by synthesizing more mitochondrion to ensure that it's demand of energy is met.
