1.  Snapdragons can be red (RR), white (WW), or pink (RW).   Cross a red snapdragon with a pink snapdragon.  Give the genotype and phenotype percentages. 

RR (hom0zygous dominant) - 50%

RW (heterozygous) - 50%

Red flower - 50 %

Pink flower - 50%

Explanation:

To solve this problem, we need to use a Punnett square. A red snapdragon has a genotype of RR and a pink snapdragon has a genotype of RW.

      R    R

R    RR  RR

W  RW  RW

50% of the offspring would have the RR genotype (hom0zygous dominant) and 50% would have the RW genotype (heterozygous). The RR genotype results in a red flower, and the RW genotype results in a pink flower, so 50% of the offspring would be red and 50% would be pink.

1. (1.2kw)x(15/60hours) = .3kwh --> a

2. (5kw)x(90/60hours)x(8cents/kwh) = $0.60 --> d

3. microwave --> 1200 watts = (1.2kw)x(6/60hours) = .12kwh

coffee-maker --> 900 watts = (.9kw)x(10/60hours) = .15kwh

therefore, it requires more energy for the coffee-maker to do the same amount of work.

so the answer is a.

it is a
