Answer:
E) 2
Explanation:
The energy transfer through the food chain is not 100% from one consumer to another, or from the producer to the primary consumer, but instead it is around 10%. This means that if a producer has the 100% of energy, as it is the one that produces it, the primary consumer will only get 10% of its energy while consuming it, while the predator of the the primary consumer will only 10% from the primary consumer, or rather only 1% from the energy of the producer. In this case we have 200 kg of plant material. The plant material represents a producer, thus it is the one with 100% of energy. A herbivore will eat the plant material, getting 10% of its energy, thus this plant material is supporting about 20 kg of herbivore. The predator of the herbivore gets only 10% from the herbivore's energy, or only 1% of the producer's energy, thus only 2 kg of predator can be supported by the initial plant material.
B. Is characterized by four different zones.
Answer: cellular metabolism
Explanation:
Cellular metabolism is chemical reactions that takes place in living organisms so that they will be able to maintain life. Cellular metabolism is made up of thousands of genes, metabolites and proteins.
Cellular metabolism is affected by the sympathetic nervous system but is not affected by the parasympathetic nervous system.
During acclimatization over a few days to weeks, the body produces more red blood cells to counteract the lower oxygen saturation in blood in high altitudes. Full adaptation to high altitude is achieved when the increase of red blood cells reaches a plateau and stops.Heart rate is controlled by the two branches of the autonomic (involuntary) nervous system. The sympathetic nervous system (SNS) and the parasympathetic nervous system (PNS). ... At the beginning of exercise, your body removes the parasympathetic stimulation, which enables the heart rate to gradually increase.
