Answer:
lateral inhibition in the retina
Explanation:
Horizontal cells are in contact with photoreceptor cells through the synapse. One photoreceptor forms an excitatory synapse with horizontal cell in the adjacent regions of the retina while the horizontal cell forms an inhibitory synapse with another photoreceptor.
Hence, as one photoreceptor activates the horizontal cell, the horizontal cell, in turn, inhibits the other photoreceptor cell and thereby reduces the quantity of neurotransmitter released at the bipolar cell. In this way, horizontal cells transmit lateral inhibitory stimulus to the photoreceptor which in turn improves the contrast at the edges of the object.

Answer:
Type of nucleic acid.
Explanation:
Virus may be defined as the organism that can contains both DNA and RNA as their genetic material. Virus acts as non-living outside the host environment and later acts as living organism inside the host.
Some virus that particularly contain DNA as genetic material. Some virus has the ability to transform RNA into the DNA molecule. Some virus contains only RNA as their genetic material and DNA is not involved in their life cycle.
Thus, the correct answer is option (a).
