The theory behind narrow row corn production is that yields of any crop will be maximized when plants are uniformly distributed across the field. To achieve this, the spacing between all plants between and within the rows must be equal. For an equidistant plant spacing with 30,000 plants per acre, both the row spacing and distance between plants within the row would be 17.4 inches. In a 15-inch row system, plants would be 13.9 inches apart in the rows.
Swallowed air. Aerophagia, or air swallowing, is a common cause of gas in the stomach. Everyone swallows small amounts of air when eating and drinking. However, eating or drinking rapidly, chewing gum, smoking, or wearing loose dentures can cause some people to take in more air. Burping, or belching, is the way most swallowed air - which contains nitrogen, oxygen, and carbon dioxide - leaves the stomach.
Share to: In the breathing system, the air enters at the nostrils (nares) , passes through the nasal cavity (where some smell detectors are located) , and enters the trachea.Sid â¦ e branches of this system the Eustachian tubes communicate with the middle ear to allow for the balancing or air pressure across the eardrum.he air we breath in normally enters through our nose. This is  because The hairs inside our nostrils catch pathogens(germs) and  particles. Also when the air enters our nas â¦ al cavity small hairs  called cillia further help to catch pathogens, as well as  moistening and warming the air.
