Genetic modifications to livestock would most likely suit to increase their longevity and marketability.
Explanation:
One of the bigger problems facing livestock is disease. Genes for bacterial resistance would likely increase the yield of livestock over time. Additionally, livestock raised in hot/cold climates could benefit from genes that adapt them better to these conditions. For example, cattle raised in hot conditions would benefit from genes that increase sweating or decrease passive water loss like through defecation.
Additionally, tailoring livestock to consumer desires would increase marketability, and therefore profit. For example, an ideal steak has a set fat content. Genetically modifying cows to maintain this fat content would increase the value of its meat.
The answer is true. It is because the activated sludge
process made use of the aeration in which air being mixed with a substance
together with a bacteria and protozoa that is in a biological floc that will
help treat the wastewater.
