Acomatose infant is brought to the er. in the course of the examination, plasma ammonia was found to be elevated 20-fold over normal values. urine orotic acid and uracil, that require carbamoyl phosphate for their formation, were both greater than normal. a defect of which of the following enzymes is the most likely diagnosis? a. arginaseb. argininosuccinate lyasec. carbamoyl phosphate synthetase 1 (ammonia substrate)d. carbamoyl phosphate synthetase 2 (glutamine substrate)e. ornithine transcarbamoylase

the number of protons in the nucleus of a given element. has slight luster and conducts electricity at high temperatures like metal.but like a nonmetal,boron is brittle and does not conduct electricity well at low temperatures. in graphite, carbon is a soft,brittle solid.it is reflective,ductile,or malleable.

b. is the answer hoped i        

nacl or sodium chloride is an ionic compound. this is because an ionic compound pertains to a compound that consists of positively and negatively charged ions. in this case, na (sodium) has a tendency to lose one electron when it reacts with with other atoms, so the resulting sodium ion contains 11 protons and 10 electrons, thus making it positively charged (na+), when chlorine reacts, it usually gains one electron to form an ion called chloride, thus making it negatively charged ( since the ions are oppositely charged, they attract.
