Answer:
The electrical and diffusion potentials for K+ will be equal in magnitude and opposite in direction.
Explanation:
The cell potential may be defined as the potential difference between the inside of the cell and outside the cell. This difference is important for the transmission of nerve impulse.
The equilibrium condition may be defined as the condition at which the exit and the entrance of the ions will be equal. As the information in the question, Only potassium ions will move inward and outward of the cell. The potassium ions will move in opposite direction since the equilibrium has been reached.
Thus, the correct answer is option (D).

Answer:
evolution
Explanation:
adaptations are the result of evolution. Evolution is a change in a species over long periods of time.
Answer:
Sensory adaptation.
Explanation:
When the sensory receptors are exposed to a constant stimulus for a prolonged period, the receptors decrease their ability to respond and this leads to a decreased sensitivity of the stimulus. This phenomenon is referred to as sensory adaptation.
Sensory adaptation occurs in all of our five major senses. From taste to smell, touch, sight and hearing. This mechanism is used by the body to ignore trivial and unimportant stimuli and direct our attention to other stimuli around us.
Other examples of sensory adaptation are;
A) When we adapt to constant noise coming from a particular source such as a disco hall.
B) When we no longer notice the smell of our deodorants.
C)When the eyes adjust and adapt to a dark room.
