Answer: Cardboard containers are best for protecting the riboflavin content of milk.
Riboflavin or vitamin B2 acts as a coenzyme in the metabolism of flavin mononucleotide and flavin adenine dinucleotide. The riboflavin is destroyed by irradiations and ultraviolet rays and therefore the milk is sold in opaque containers which are stable to heat. The tetra pack used now days is made up of cardboard and best suitable for using as a container to protect the riboflavin content of the milk.

Answer:
B) Nitrogen-fixing bacteria and lightning
Explanation:
Nitrogen cycle is the natural process in which atmospheric nitrogen is converted into nitrite and nitrate with the help of bacteria.
Nitrogen cycle is directly dependent on nitrogen-fixing bacteria and lightning.
As bacteria are responsible for most of the chemical conversion in the nitrogen cycle such as nitrogen fixation (first step) is done by soil bacteria (Cyanobacteria) that form ammonia, which is toxic to plants; nitrification in which ammonia is converted into nitrites and nitrates with the help of Nitrobacter and denitrification bacteria involve Pseudomonas, and Achromobacter which convert nitrite and nitrate into nitrogen.
The lightning breaks nitrogen molecules and allow it to combine with oxygen in atmosphere which further dissolve in rain and form nitrates.
Hence, the nitrogen cycle is most directly dependent upon nitrogen-fixing bacteria and lightning and the correct option is B.
