Answer:
b. Frank received the mutant chromosome from his father. Nondisjunction occurred in his father during the first meiotic division.
Explanation:
As you can see in the question above, Frank has Klinefelter syndrome which causes him to have normal skin patches and skin patches without sweat glands. Her mother has completely normal hair, which may indicate that the defective gene was not supplied by her. In addition, Frank's father has anhydrotic ectodermal dysplasia, an X-linked condition where the skin does not contain sweat glands.
Although Frank's father's defective gene is linked to the X chromosome, it is likely that Frank inherited the defective gene from his country. This may have occurred because during meiosis I, his father's genes did not show disjunction. As a result, Frank presents a mosaic of his phenotype, because an inactivation of the X chromosome occurred.

Below:
Explanation:
Saturated fatty acids lack double bonds between the individual carbon atoms, while in unsaturated fatty acids there is at least one double bond in the fatty acid chain. Saturated fats tend to be solid at room temperature and from animal sources, while unsaturated fats are usually liquid and from plant sources.

choices are:
Mike is right because the atomic mass of lithium is 6. There are 3 protons and 3 electrons in the atom. 3+3=6
Joan is right because the atomic number of carbon is 6. There are 3 protons and 3 electrons in the atom. The atomic number shows the number of protons plus the number of electrons. 3+3=6
Joan is correct because carbon is a neutral atom. There are the same number of protons and electrons in the atom pictured.
Mike is correct because the atomic number shows the number of protons in all atoms. There are 3 protons and the atomic number of lithium is 3.
Li has atomic no. 3 and mass 7. so the correct ans is Mike is correct because the atomic number shows the number of protons in all atoms. There are 3 protons and the atomic number of lithium is 3.
