Kidneys compensate for acid-base imbalances by : Reabsorbing HCO₃ from urine back to the blood and also secreting H⁺ back to the urine.
<h3>Acid-base Imbalance </h3>
When the amount of acid or base produced in the human body is greater than or less than the required amount of acid or base, and the rate of excretion by the kidneys is above or below normal, the body will experience an Acid-base imbalance situation.
To correct acid-base imbalance in the body the kidney will reabsorb HCO₃ form the urine and while secreting Hydrogen ions back to the urine.
Hence we can conclude that Kidneys compensate for acid-base imbalances by : Reabsorbing HCO₃ from urine back to the blood and also secreting H⁺ back to the urine.

Non-disjunction occurred during meiosis II in the maternal germinal line. Non-disjunction may occur during meiosis I or meiosis II.
<h3>What is non-disjunction?</h3>
Non-disjunction refers to the phenomena where homo-logous chromosomes or sister chromatids are not separated properly during cell division.
Non-disjunction during meiosis II is due to the failure of the sister chromatids to separate during Anaphase II.
In this case, the genotype of the father is 5/8, thereby transmitting alleles number 5 and 8.
Moreover, the genotype of the mother is 6/3, thereby she is able to transmit alleles number 6 and 3.

Answer:
Hi There! :P
Explanation:
A controlled experiment is simply an experiment in which all factors are held constant except for one: the independent variable. A common type of controlled experiment compares a control group against an experimental group. All variables are identical between the two groups except for the factor being tested.

I) According to FDA there are about 38 toxic contaminants of bottled water may include, Chloride, Coliform, Arsenic, Iron, Manganese, phenols, Dissolved solids, Zinc,and Flouride. It is the work of FDA to allow certain levels of these contaminants in bottled water. Higher levels than the recommended levels may be toxic and dangerous to human beings.
ii) These contaminants are from different sources, for example chloride ions or chlorine is from the disinfectant used to treat water since the compounds are chloride compounds and also other byproducts of chlorine based disinfection. The CfCs is from the plastic making the bottle if water is exposed to sunlight.
