D. proteins is the right answer
The first to the left is the Optic Nerve, The second to the left is the Optic Tract while the one to the right is Optic Chiasm of the labeled cranial nerves.
<h3>What are cranial nerves?</h3>
The cranial nerves are of 12 pairs and can be found at the back of the human brain. These nerves specialize in sending electrical signals to the brain, face, neck and torso.
Optic nerve comprises of nerve fibers in millions and sends visual messages to the brain for sight and is located at the top left of the labelling. The optic tract serves also for visual information to the lateral geniculate bodies and located at the bottom left while the optic chiasm at the right side of the diagram sends signal to the optic tract.

Answer:
Here, we have a composition passage and we are required to fill in the with missing words. The missing words are highlighted in bold format and underlined.
Lecithins and cephalins are both <u>glycerophospholipids;</u> they consist of <u>glycerol</u> with fatty acids forming <u>ester</u> bonds with the first and second <u>hydroxyl </u>groups. The third <u>hydroxyl</u> group of the <u>glycerol </u>forms a<u> phosphate bond </u>with phosphoric acid, which forms another<u> phosphate </u>bond with an amino alcohol. In lecithins, the amino alcohol is <u>choline;</u> in cephalins, the amino alcohol is usually <u>ethanolamine. </u>
Explanation:
Lecithin is a chemical complex composed primarily of fatty acids, glycerol, phosphoric acid, and choline. It can be present in egg yolks, soybeans, sunflower seeds, and plant seed cells and is completely normal. Soybean and sunflower lecithins contain much more important fatty acids than rapeseed lecithin, making them nutritionally more useful.
Phosphatidylethanolamine, also known as cephalin, is a phosphoglyceride that, like phosphatidylcholines and lecithins, is a component of biological membranes. A glycerol residue esterified by two fatty acids and a phosphoethanolamine residue gives rise to phosphatidylethanolamines. They're made by combining CDP-ethanolamine with diglycerides and releasing a CMP molecule. Phosphatidylcholines are formed when S-adenosylmethionine methylates the amine in ethanolamines. They're mostly found in the inner layer of plasma membranes' lipid bilayers.

Answer:
Svalbard is a kind of insurance policy for other gene banks. Plant breeders and researchers depend on seed banks around the world to obtain varieties with useful traits that they need. If those seed banks later lose their own resources, because of natural or man-made disaster, the collections could be restored by getting the copies back from svalbard.
