Identify the difference between facilitated diffusion and regular diffusion.

a)in facilitated diffusion, substances move from areas of lower concentration to areas of higher concentration. in regular diffusion, substances move in the opposite direction.
b)facilitated diffusion is a form of active transport. regular diffusion is a form of passive transport.
c)facilitated diffusion involves special membrane proteins that transport substances across the cell membrane. regular diffusion does not involve proteins.
d)facilitated diffusion requires an input of energy to transport substances across the cell membrane. regular diffusion does not require an input of energy.

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?
