The amount of greenhouse gases that agriculture and farming produce varies around the world. This is because each livestock production system utilizes its resources differently. Agricultural systems are often categorized into two types of systems:extensive farming and intensive farming.
Extensive farming is a type of agriculture that is mainly a pasture-based and land-based system. Extensive farming uses low labor and input resources. This type of farming utilizes natural resources and results in lower yield per unit of land than intensive farming. In beef cattle production, for example, cattle in an extensive system would graze in a pasture.
Intensive systems have more concentrated operations and are often more mechanized. This system uses higher amounts of labor and resources per unit of land, but it also produces greater yield per unit of land than extensive farming systems. A feedlot is an example of an intensive system for beef cattle production.
Now, the amount of cattle we are raising is in the United States as of January 1, 2015 totaled 89.8 million. This might be a cause even of its not proven to be correct. However, this can be a correct estimate. I suggest look into other sources for information!

Explanation:
Answer:
c)peptidoglycan synthesis and cell walls
Explanation:
The main points of action of antibiotics are inhibition of bacterial cell wall peptideoglycan synthesis, cytoplasmic membrane damage and interference with nucleic acid and protein synthesis.
The bacterial cell wall is formed by peptideoglycan. Penicillin and other antibiotics prevent its complete synthesis, consequently weaken the cell wall and the cell lyses. Because human cells lack peptideoglycan, penicillin has low toxicity to the host cell. The synthesis of peptideoglycan components is affected by β-lactam antibiotics (penicillins and cephalosporins).
For this reason, we can conclude that the antibiotics described in the above question are those that target peptidoglycan and cell wall synthesis.
