Answer:
Due to less steps and requires less energy.
Explanation:
The bacterial cell is able to use glucose first as an energy source then switch to lactose because glucose requires less steps and less amount of energy for the break down as compared to lactose. If lactose is the only sugar available to the bacterial cells, then bacterial cells will use it as energy source for the production of energy. In order to use lactose, the bacteria must express the lac operon genes, which encode the main enzymes for lactose uptake and metabolism.

Caisson disease is an acute neurological condition that only occurs in deep sea divers, caused by a gas embolism that blocks a vessel and transportation of oxygen.
Answer:
Gap Junctions.
Explanation:
Gap junctions are intercellular channels that allows the cell transfer of molecules, ions and electric impulses.
They are connected through the protein channel and are found in many parts of vertebrate and invertebrate nervous systems.
Its most important function is to control the activities of adjacent cells.
Unlike ionic bonds, covalent bonds involve the sharing of electrons between atoms.
