Two star-connected generators are connected in a parallel and supply a balanced load of 1500kva at 11kV line voltage and 0.8lagging power factor. The Synchronous reactnces of the two machines respectively are: 35 ohms and 40 ohms. The prime mover governors  of the two machines are adjusted so as to equally share the power load The phase current in one machine is 43A at a lagging power factor Calculate

CHAPTER 19 VIRUSES

1] Would you classify viruses as living or nonliving?  Give reasons to explain your answer.

2] Draw a labeled diagram and describe the structure of a Bacteriophage T4. Explain the function of each part.

3] List the differences between the lytic and lysogenic reproductive cycle of a phage.

CHAPTER 14 MENDEL AND THE GENE IDEA

4] Based on Mendel’s model explain the following terms

a] Alleles

b] Dominant allele

c] Recessive allele

d] Homozygous

e] Heterozygous

f] Phenotype

g] Genotype

5] When Mendel crossed true breed purple flowers with true breed white flowers what did he observe in the F1 generation? Explain the result using a Punnett square.

6] When 2 plants in the F1 generation were crossed, what result did Mendel see (for flower color) in the F2 generation? Explain with a Punnett square.
