Idk the genotype but I have to answer a question so
The name of the tear collecting structure under the skin near the bridge of the nose is the lacrimal sac. The lacrimal sac is part of the lacrimal drainage system or the lacrimal apparatus. The tears are produced in the lacrimal gland and will drain through a hole near the lower palpebral conjuntiva called the puncta which serves as the entrance in the lacrimal system. The tears will now enter the canalicula which serves as the passage way from the puncta to the lacrimal sac. Lastly, the tears in the lacrimal sac will drain to the nasolacrimal duct and to the nose. This also explains why we get runny nose when we are crying.
C) The complete loss of plant life in the area occupied by the surface mine.
Hope this helped!
Answer:
Essential bonding's are developed in the amino acids leading to formation of DNA. During cellular interaction they also provide pathways for active transportation.
Explanation:
Hydrogen bonding causes the folding of protein thereby stabilizing their structure and formation of DNA and essential bio products. These H+ bonds holds the double helix DNA molecule which zips and unzips during the cell division leading to the formation of cells with new genetic material. Also during cellular interaction and transfer of material through a permeable membrane, there is a proton oriented gated channel that causes active transport.
Hence, hydrogen bonds and van der Waals interactions are necessary for cells
