Question: Research in the field of nutrition has greatly contributed in finding out the essential facts about how environmental depletion can lead to crucial nutrition-related health problems like contamination, spread of contagious diseases, malnutrition, etc. Moreover, environmental contamination due to discharge of agricultural as well as industrial chemicals like organocholrines, heavy metal, and radionucleotides may adversely affect the human and the ecosystem as a whole. As far as safety of the human health is concerned, then these environmental contaminants can reduce people's nutritional status and health. This could directly or indirectly cause drastic changes in their diet habits. Hence, food-based remedial as well as preventive strategies are essential to address global issues like hunger and malnutrition and to enable the susceptible people to adapt themselves to all these environmental as well as socio-economic alterations.

Question: Two chains of DNA twist around each other to form a DNA double helix with the phosphate-sugar backbone spiralling around the outside, and the bases pointing inwards with adenine base pairing to thymine and guanine to cytosine. The specificity of base pairing occurs because adenine and thymine align form two hydrogen bonds, whereas cytosine and guanine form three hydrogen bonds. The two strands in a double helix must therefore be complementary, with their sequence of bases matching such that the adenines of one strand are paired with the thymines of the other strand, and so on.:4.1
Is there an answer to this question: What causes the specificity of base pairing?

Answer: adenine and thymine align form two hydrogen bonds, whereas cytosine and guanine form three hydrogen bonds

Question: From its origins in the fur trade, the Hudson's Bay Company is the oldest corporation in North America and was the largest department store operator in Canada until the mid-1980s, with locations across the country. It also previously owned Zellers, another major Canadian department store which ceased to exist in March 2013 after selling its lease holdings to Target Canada. Other department stores in Canada are: Canadian Tire, Sears Canada, Ogilvy, Les Ailes de la Mode, Giant Tiger, Co-op, Costco and Holt Renfrew. Grocery giant Superstores carry many non-grocery items akin to a department store. Woolco had 160 stores in Canada when operations ceased (Walmart bought out Woolco in 1994). Today low-price Walmart is by far the most dominant department store retailer in Canada with outlets throughout the country. Historically, department stores were a significant component in Canadian economic life, and chain stores such as Eaton's, Charles Ogilvy Limited, Freiman's, Spencer's, Simpsons, Morgan's, and Woodward's were staples in their respective communities. Department stores in Canada are similar in design and style to department stores in the United States.
Is there an answer to this question: What business was the Hudson's Bay Company originally not involved in?
