How does improving food-storage facilities make farming more sustainable? a. it decreases the amount of water needed. b. it keeps food from rotting as quickly and being wasted. c. it decreases the amount of land needed. d. it keeps chemicals from entering the watershed.

I think the answer is B, it keeps food from rotting as quickly and being wasted. Food-storage facilities. Food storage allows food to be eaten after some time after the harvest rather than solely immediately. This ensures that there is food even during the time when there is no harvests and also prevents wastage of food at the time of harvest

For cyclohexane compounds drawn in a chair conformation:   -axial bonds are vertical  -equatorial bonds are parallel to two bonds within the ring.  thus, as i assume the chair conformation is drawn:   -the x group is in an axial position, as are the five other vertical bonds.  -three axial bonds are on the top face of the ring  -the other three axial bonds are on the bottom face  the position of the second substituent on each ring carbon is equatorial.  gauche groups must be on an adjacent carbon such as carbon 6 and carbon 2, and also gauche groups are rotated by 60 degrees relative to each other.  drawing the newman projections for c1–c2 and c1–c6 aids in visualizing the groups that are gauche to the y group on c1.  click this link and watch some academic videos that may you more understand the topic
