Arrange the following statements to create the proper order of events in the humoral immune response: 1. The helper T cell interacts with antigen presented in an MHC-II molecule.
2. The B cell divides to produce memory B cells and effector B cells.
3. Antibodies specific for the antigen are produce in large numbers.
4. The helper T cell secretes interleukin-2.
5. The B cell presents antigen fragments specific for its surface antibodies using MHC-II molecules on the cell surface.

Coat color in cats is determined by genes at several different loci. at one locus on the x chromosome, one allele (x ) encodes black fur and another allele (xo) encodes orange fur. females can be black (x x ), orange (xoxo), or a mixture of orange and black called tortoiseshell (x xo). males are either black (x y) or orange (xoy). bill has a female tortoiseshell cat named patches. one night, patches escapes from bill\'s house, spends the night out, and mates with a stray male. patches later gives birth to the following kittens: one orange male, one black male, two tortoiseshell females, and one orange female. what are the genotypes of patches, the stray male, and the kittens?
