The function of cilia is to move water relative to the cell in a regular movement of the cilia. This process can either result in the cell moving through the water, typical for many single-celled organisms, or in moving water and its contents across the surface of the cell.

Neural impulses are transmitted to bipolar cells when light energy enters the eye and triggers CHEMICAL CHANGES in the rods and cones. This process is known as phototransduction.

Phototransduction refers to the process by which photoreceptors convert light into electrical signals.

Photoreceptors (i.e., rod and cone cells) are specialized cells in the retina of the eye which are capable of converting light into electrical signals and thus trigger different physiological processes.

Phototransduction is triggered by the activation of signaling proteins, that open or close ion membrane channels in photoreceptor cells.

Objects are brought into focus on the retina by changes in the curvature and thickness of the lens.

The lens basically directs light rays onto the retina. The lens is clear and replaceable if necessary. As we age, our lenses deteriorate, necessitating the use of reading glasses.

The lens is normally clear and is located behind the iris. The pupil directs light to the lens.

Small muscles attached to the lens can cause the lens to change shape, allowing the eyes to focus on objects that are close or far away.

Light bends (refracts) and focuses on the retina at the back of the eye as it passes through the lens.

The lens's thickness and curvature can be adjusted to focus on objects at various distances and ensure that the image is as clear as possible (this process is known as accommodation).

Thus, eye lens helps to focus the object.

Answer:  The Cathode

Explanation:

Reduction always occurs at the cathode, and oxidation always occurs at the anode. Since reduction is the addition of electrons, electrons must travel toward the site of reduction. In an electrolytic cell the negative charge is on the cathode, while the positive charge is on the anode.

Rocks from the Ordovician Period contain evidence that plants began colonizing dry land at this time. Most experts agree that the ancestors of land plants first evolved in a marine environment, then moved into a freshwater environment and finally onto land.

Ordovician Period, in geologic time, the second period of the Paleozoic Era. It began 485.4 million years ago, following the Cambrian Period, and ended 443.8 million years ago, when the Silurian Period began. Ordovician rocks have the distinction of occurring at the highest elevation on Earth—the top of Mount Everest.
