Answer:
See the answer below
Explanation:
<em>Zara should keep the clownfish and the goldfish in separate tanks - the goldfish in a freshwater tank and the clownfish in a salt water tank.</em>
<u>If the goldfish is kept in a salt water tank instead of freshwater, it may die due to dehydration</u> because the salt water would be hypertonic to the cells of the fish. Water would move osmotically from the cells of the fish into the surrounding water and the fish may eventually die due to dehydration.
<u>If the clownfish is kept in freshwater instead of salt water, it may die due to excessive water</u>. The freshwater would be hypotonic to the cells of the fish and water would move osmotically from the surrounding water into the cells of the fish. Eventually, the cells would become turgid and may start lysing, leading to the death of the fish.

The best answer is D.
Facilitated diffusion is a transport mechanism in which carrier proteins shuttle molecules across a plasma membrane without using the cell's energy . The energy is provided by the concentration gradient i.e. molecules are transported from higher to lower concentrations, into or out of the cell.
Glucose binds to carrier proteins of the GLUT family. Once bound, the change shape so as to fit in the membrane channels and thus they translocate the glucose molecule from one side of the plasma membrane to the other.
