Answer:
The correct answer to the question: When the pH of the extracellular fluid drops, the kidneys:____, would be: C: excrete fewer bicarbonate ions.
Explanation:
The pH of the human body, given by the extracellular fluid that flows and is contained in it, holds a narrow margin between 7.35 and 7.45. When hydrogens ions increase, and bicarbonate ions decrease, in any of these fluids, be it blood, CSF, or any other, then we known that a person´s body is going into acidosis because the pH level is dropping. However, when the scenario is the opposite, with more bicarbonate ions, than hydrogen ions, then we are talking of an alkalosis. In order for the body to restore its normal levels, it has a series of mechanisms that will ensure the reestablishment of balance. One such mechanism is the excretion of elements through the urine, by the kidneys. In a case of acidosis then, the correct procedure is that kidneys produce urine charged with the excess hydrogen atoms and re-uptakes bicarbonate ions that might have escaped while producing urine. The urine will become acidic then. This is why the answer is C.
The non-Hispanic black-white discrepancy has plateaued in recent years, and this is mostly because the prevalence of asthma among non-Hispanic black children has stopped rising.
From 2001 to 2009, there was an overall rise in the prevalence of childhood asthma; this was followed by a plateau and a drop in 2013. From 2001 to 2013, multivariate logistic regression revealed no change in prevalence among non-Hispanic white, Puerto Rican, and children living in the Northeast and West; increasing prevalence among children aged 10 to 17 who are poor and reside in the South; increasing then plateauing prevalence among non-Hispanic black children aged 5 to 9, and increasing then decreasing prevalence among Mexican children aged 0 to 4 years. Black-white gaps between non-Hispanic races ceased widening, while Puerto Rican children continued to have the highest incidence.
