A female is heterozygous for an X-linked gene. If nondisjunction happens for the sex chromosome during Meiosis II, one aneuploid gamete would contain: A) 2 copies of the X chromosome that are identical and a Y chromosome
B) 2 copies of the X chromosomes that are identical
C) an X chromosome and a Y chromosome
D) 2 copies of the X chromosome that are not identical

Cells a and b are the same size and shape, but cell a is metabolically quiet and cell b is actively consuming oxygen. oxygen will diffuse more quickly into cell because . b the oxygen molecules inside cell b have a higher kinetic energy b. a its membrane transport proteins will not be saturated c. a the diffusion gradient there is shallowerd. b the diffusion gradient there is steeper
