Answer:
The correct answer will be- such as poor water management and nutrient management leads to 70-90% reduction in the yield.
Explanation:
The productivity of the crops is directly influenced by both biotic factors and abiotic factors.
The factors which are living and reduces the yield of the crops creates biotic stress like pest and disease which result in 10-30% loss in the yield o crops.
The factor which is non-living and creates stress for the crops is known as abiotic stress like poor water and nutrient management which leads to the loss of 70-90% productivity.
The sympathetic nervous system is a part of the autonomic nervous system that carries stress responses or "flight or flight" responses that involves feelings of rush. The activation of sympathetic nervous system therefore increases the heart rate. The parasympathetic nervous system is another part of the autonomic nervous system which is responsible for "rest and digest" responses that involves feelings of relaxation. The activation of the parasympathetic nervous system decreases the heart rate.
While moving in between areas of land glaciers erode the land around them, this eroded land leads to weathering from the sand and rocks eroded. Example The Grand Canyon
S phase is the DNA synthesis phase. During this portion of the cell cycle, the cell replicates its entire complement of DNA. It also forms the centrosome, which is the microtubule-organizing center that will eventually help the cell pull apart the DNA that will be divided between daughter cells.
