Answer:
From my side I think it is Photoreceptors cells :
A photoreceptor cell is a specialized type of neuroepithelial cell found in the retina that is capable of visual phototransduction. The great biological importance of photoreceptors is that they convert light (visible electromagnetic radiation) into signals that can stimulate biological processes. To be more specific, photoreceptor proteins in the cell absorb photons, triggering a change in the cell's membrane potential.
There are currently three known types of photoreceptor cells in mammalian eyes: rods, cones, and photosensitive retinal ganglion cells. The two classic photoreceptor cells are rods and cones, each contributing information used by the visual system to form a representation of the visual world, sight. The rods are narrower than the cones and distributed differently across the retina, but the chemical process in each that supports phototransduction is similar. A third class of mammalian photoreceptor cell was discovered during the 1990s: the photosensitive ganglion cells. These cells do not contribute to sight directly, but are thought to support circadian rhythms and pupillary reflex.
Explanation:
A. Organic catalysts are called enzymes.
Explanation:
The true statement of all is that organic catalysts are called enzymes. For example, saliva in the mouth is made up of different enzymes which are secreted in the human body.
- Catalysts reduces the activation energy and makes reaction proceed very fast. They generally increase the rate of chemical reactions.
- Catalysts like temperature affects the rate of chemical reaction. Chemical reactions increases as temperature increases.
- Catalysts in the human body are very useful because they help chemical reactions in the body to proceed at a much faster rate.

Bitter taste, high pH, and caustic Bitter are the characteristics of base.
<h3>What are the characteristics of base?</h3>
Bases have bitter taste, soapy feel, turn red litmus paper blue. Bases are substances that contain metal oxides or hydroxides. Its pH is higher than 7 up to 14.
So we can conclude that bitter taste, high pH, and caustic Bitter are the characteristics of base.
