Answer:
2. Such regions play a significant role in gene regulation. That is why they remain conservative under the influence of natural selection.
Explanation:
Within the genome there are many non-coding regions that control the expression of master developmental genes such as, for example, Hox major transcription factors (TFs) in animals and MADS-box TFs in plants. These gene regulatory regions (e.g., promoters and enhancers) are generally evolutionarily conserved within certain taxonomic groups. In consequence, such non-coding regions are well known to be conserved and interact in a sequence-specific manner with major transcription factors in order to regulate developmental pathways.
Answer:

Your bronchioles are some of the smallest airways in your lungs. Inhaled air passes through tiny ducts from the bronchioles into elastic air sacs (alveoli). The alveoli are surrounded by the alveolar-capillary membrane, which normally prevents liquid in the capillaries from entering the air sacs.

Answer:
patented products
Explanation:
A patented product is one that has gone through a public concession process that has ruled that a particular company or manufacturer has exclusivity in the manufacture and distribution of that product on the market.
There is a concern about the existence of patented products in relation to genetically modified organisms, because this may prohibit the manufacture of similar products. In the case of agricultural crops, this concern becomes even greater, because the controversy of genetically modified and authenticated crops may end up being invaded and contaminating the plantation that has not been genetically modified, causing the producer to lose production rights for the contaminated crop.
