Answer:
True
Explanation:
The bacterial cultivation refers to growing the bacterial species for exploitation or use. But the humans are not able to cultivate the majority of the bacterial species present which could be accounted for many reasons.
The bacteria can mutate very easily through the exchange of genetic material. Some bacterial species cannot be isolated. New bacterial species are discovered in less period of time and some species fail to grow on the growth medium due to lack of information. Till now only one percent of bacterial species have been cultivated.
Thus, true is correct.
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:
Changes in the composition of the atmosphere
Explanation:
Although this answer is very vague and generalized, it is the correct answer.
The increase in greenhouse gas emissions in the atmosphere from modern manufacturing and engineering has increase carbon dioxide and methane concentrations in the upper atmosphere. These gasses have a chemical composition that allows the absorption and release of longwave radiation back to the Earth's surface slowly increasing the global average temperature.
Kinetic is movement and potential is stored energy
