Answer:
Concentration gradient
Explanation:
When the concentration of molecules and ions is compared to the concentration of ions and molecules in another area, the difference in the concentration will be called the concentration gradient.
The concentration gradient is the factor which determines the rate and direction of the molecules and ions in the environment which could be physical or biological.
Thus, concentration gradient is the correct answer.
Answer;
-Cochlea; rods and cones; retina
Making an analogy between hearing and vision, the auditory hair cells in the cochlea are similar to the rods and cones in the retina.
Explanation;
-There are two types of photoreceptors in the human retina, rods and cones. Rods are responsible for vision at low light levels (scotopic vision). They do not mediate color vision, and have a low spatial acuity.
-Cones are active at higher light levels (photopic vision), are capable of color vision and are responsible for high spatial acuity. The central fovea is populated exclusively by cones.
The cochlea is a portion of the inner ear that looks like a snail shell. It receives sound in the form of vibrations, which cause the stereocilia to move. The stereocilia then convert these vibrations into nerve impulses which are taken up to the brain to be interpreted.
