Intermediate-day Onions produce bulbs where the total amount of daylight is approximately 12-14 hours, which is the amount mid-section states receive in the summer. Intermediates are also known as day-neutral onions. Long-day Onions produce bulbs where the total amount of daylight is 14-16 hours.
Anaerobic Zone. The anaerobic zone is slightly more intense than the aerobic zone. Anaerobic means without oxygen, so don't be surprised if you are unable to speak except for short words at a time in this zone. The anaerobic zone is 80 to 90 percent of your maximum heart rate.erobic Zone. The aerobic target zone is 70 to 80 percent of your maximal heart rate. Multiply your maximum heart rate by this percentage to determine the intensity you must maintain to remain in this zone.
From Wikipedia, the free encyclopedia. Anaerobic respiration is a form of respiration using electron acceptors other than oxygen. Although oxygen is not used as the final electron acceptor, the process still uses a respiratory electron transport chain; it is respiration without oxygen. In aerobic organisms undergoing respiration, electrons are shuttled to an electron transport chain, and the final electron acceptor is oxygen. Molecular oxygen is a highly oxidizing agent and, therefore, is an excellent acceptor.
