Put the components of the visual projection pathway in order starting with the retina and ending with the brain. In order, starting from the lowest to the highest, we have:
- Bipolar and ganglion cells of the retina
- Hemidecussation in optic chiasm
- Optic tracts
- Lateral geniculate nucleus (LGN) of the thalamus
- Optics Radiation
- Primary visual cortex in the occipital lobe
The visual projection pathway is referred to as the channel through which electrical impulses created by the retina are transmitted to the brain.
When light penetrates the eye into the retina;
- The bipolar and ganglion cells carry the signals from photoreceptors (cones and rods) to ganglion cells, either actively or passively.
- The axons of the ganglion gather and unite to form the optic nerve.
- The optic nerve leads to the optical chiasm where hemidecussation of the optic nerve fiber takes place.
- In the Optic Chiasm, the optic tract contains the nasal fibers that join from the left eye and connect with temporal fibers from the right eye, vice versa.
- The lateral geniculate nucleus (LGN) which connects from the optic tracts has nerve endings that send optical radiation information from the superior visual fields to the inferior visual fields.
- The primary visual cortex region is largely located on the occipital lobe of the medial brain surface, its function is to receive and process the optical radiation information sent from the (LGN).
Therefore, we can conclude that we understood the order, mechanism, and process in the visual projection pathway.

Answer:
B. False
Explanation:
Orthologs are genes that find their origin in vertical descent,, paralogous on the other hand, are genes that are related via duplication events. <em>In the case of human hemoglobin, their genes originated by duplication from an common ancestral globin gen, therefore they are paralogous.</em>

Answer: c.The process of programmed cell death.
Explanation:
Apoptosis is a kind of programmed cell death process. This can be seen in multicellular organisms. This involves the biochemical changes in the body of the organism which lead to death of cells. The changes associated in the cell during this condition includes the cell shrinkage, blebbing, condensation of the chromatin, nuclear fragmentation, decay in mRNA, and DNA fragmentation.
