The part of the human eye that acts as the detector is the

Retina.

Explanation:

The retina is the part of the eye that acts as a detector.

The retina is the innermost layer of the eye and is made up of 10 cell layers. It is in the retina that light information becomes an electrical signal to be interpreted by the brain. For an image to be perceived, it is necessary to transform the light information into an electrical signal so that the brain can interpret this information and create a perceptual representation of it.

The cells that transform light information into electrical information are called photoreceptors. There are two types of photoreceptors, the cones and the rods, whose main functional differences occur in the level of light with which they work.

In brighter environments, only cone photoreceptors work, and in low-light environments, only rod photoreceptors are active.

Once electrical information is generated in these nerve cells, the information is passed from neuron to neuron until it reaches the layer of ganglion cells that make up the optic nerve, a structure that carries information from the eye to other regions of the nervous system.

A segmented viral genome can facilitate rapid evolution of new viral strains.

Explanation:

Viruses are non-cellular entities which contain one or molecules of DNA or RNA as their genetic material enclosed inside a protein capsule.

Viruses are obligate intracellular parasites and cannot replicate outside a living cell.

The virus integrates its genome into the host genome and uses its mechanism to replicate its genome.

In other words we can say that viruses actually hijack hosts replication machinery.

The fragment of viral genome which disintegrates itself from the host genome after successful replication might carry fragments of host genome. Thus the viral genome gets modified and may evolve.
