Answer:
Mercury exposure during pregnancy can interfere with the normal embryonic nervous system development, resulting in cognitive (brain) impairment of the child.
Explanation:
Large, predatory fish such as shark, sword fish, king mackerel, tilefish, marlin, orange roughy and bigeye tuna are recommended to be avoided during pregnancy because they may have high concentrations of <em>methylmercury. </em>
Methylmercury is ingested by the mother and then crosses the placenta to reach the embryo. It acts as a neurotoxin, <em>interfering with the proper development of the nervous system</em> during gestation.
The consequences of this exposure vary and can go from attention deficit to microcephaly; <u><em>deficits in attention, cognition and motor skills</em></u> have been observed.
Because fish are part of a nutritious and balanced diet, and provide many nutrients beneficial during pregnancy, it is not recommended to stop consumption of all fish while expecting.
In the Unites States of America, the FDA (Food and Drug Administration) and the EPA (Environmental Protection Agency) have issued advice on eating fish during pregnancy. They recommend eating 8 to 12 oz of seafood low-in-mercury per week and to avoid the large fish enlisted on the first paragraph.

Life processes depend in large part on solutions. Oxygen from the lungs goes into solution in the blood plasma, unites chemically with the hemoglobin in the red blood cells, and is released to the body tissues. The products of digestion also are carried in solution to the different parts of the body. The ability of liquids to dissolve other fluids or solids has many practical applications. Chemists take advantage of differences in solubility to separate and purify materials and to carry out chemical analysis. Most chemical reactions occur in solution and are influenced by the solubilities of the reagents. Materials for chemical manufacturing equipment are selected to resist the solvent action of their contents.
