You infect E. coli cells with two strains of phage λ. One strain has a mutant host range, produces larger-than-normal plaques, and is temperature sensitive (genotype: h r t ). The other strain expresses the wild-type phenotype for these characters. Progeny phages from the lysed E. coli cells are collected and plated on a lawn of bacteria. You observe the following number of plaques for each progeny phage phenotype (which directly corresponds to its genotype):

Progeny phage genotype Number of plaques
h+ r+ t+

562
h r t 578
h+ r t 41
h r+ t+ 35
h+ r t+ 88
h r+ t 75
h+ r+ t 6
h r t+ 5
Which gene is located between the other two on the λ phage chromosome?

r
h
t

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.

in a chemical reaction, the atoms and molecules produced by the reaction are called products. no new atoms are created, and no atoms are destroyed. in a chemical reaction, reactants contact each other, bonds between atoms in the reactants are broken, and atoms rearrange and form new bonds to make the products.

its probably to later but whats the question
