Procedure
1. your teacher will prepare the warm yoost carbohydrate solutions for you,
do not get them until you are ready
2. label the 4 flasks clistilled water, monosaccharido, disaccharide, and
polysaccharide respectively.
3. measure 50 ml of each yeast carbohydrate solution with the graduated
cylinder provide and pour into the corresponding flask.
4. quickly stretch a balloon around the opening of each flask,
3. give the solution a swirl to mix the ingredients and got the reaction going
6. measure the circumference (in centimeters) of each balloon using a sining
overy 2 minutes for a total of 20 minutes.
7. be very careful when removing the balloon! pressure has been building up
inside and can cause the contents to explode if not cautious, in the sink,
very slowly lift the lip of the balloon and gently release pressure,
8. make a line graph showing the change in balloon circumference in
centimeters) for each flask over time. provide a color coded key for each,

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?
