A student remarks that it is a good thing that humans discovered how to use industrial processes to fix nitrogen because this en
sures that the nitrogen cycle can remain intact if nitrogen-fixing bacteria ever go extinct. Evaluate the accuracy of this statement. A. The statement is accurate because humans are able to fix nitrogen on a large scale that rivals the rate of the process carried out by bacteria. B. The statement is inaccurate because the nitrogen cycle does not depend on nitrogen-fixing bacteria, and their loss would not cause a problem. C. The statement is inaccurate because the product of nitrogen fixation through industrial processes does not have the same biological properties as the product of nitrogen fixation by bacteria. D. The statement is inaccurate because humans would not be able to distribute the product of nitrogen fixation from industrial processes in the same way that bacteria are able to distribute it globally now.
D. The statement is inaccurate because humans would not be able to distribute the product of nitrogen fixation from industrial processes in the same way that bacteria are able to distribute it globally now.
Explanation:
Nitrogen fixing bacteria has the responsibility in nature to trap and fix atmospheric nitrogen in ecosystems. They are very important components of the nitrogen cycle and play an important role in maintaining the balance of nutrients in nature.
If humans discover industrial processes to fix nitrogen, the process will be unsustainable in the long run if nitrogen-fixing bacteria ever go extinct because humans would not be able to distribute the product of nitrogen fixation from industrial processes in the same way that bacteria are able to distribute it globally now across several ecosystems all over the world.
Alcohol play an opposite role in water reabsorption. ADH is made in supraoptic nuclues of hypothalamus and transfers fby neuron to posterior pituatry where it gets stored and secreted. Alcohol stops the release of ADH from posterior pituatry which decreases the serum level of ADH. As the ADH level lowers it wont be able to reabsorb water from the distal/collecting tubules of kidneys leading to increase in urine volume and urination.
Four conditions are needed for natural selection to occur: reproduction, heredity, variation in fitness or organisms, variation in individual characters among members of the population.
