In the case of Henry vs Milwaulkee county

True or false

Even thou they are full-time employees of Milwaukee County and presumably meet the 12 month employment requirement Henry and Louis are not entitled to at least 12 weeks of leave to care for a newborn or adopt a child, or spouse, child or parent with a serious health condition, and their own serious health condition

A local pesticide-producing plant has been leaking high concentrations of 2,4-dichlorophenoxyacetic acid (2,4-D) into a cellulose-rich soil for years. In an attempt to reduce the 2,4-D concentrations in the soil, scientists found that 2,4-D degrading microorganisms were already present in the soil.

(a) Explain how the presence of 2,4-D degrading microorganisms was determined. Individual steps do not need to be provided but explain the method/approach and why this would provide the needed information.

(b) Taking into consideration the nutrients required for microbial growth in general, provide two reasons why the cell yield on 2,4-D might be low?

(c) Of the metabolisms we discussed (aerobic/anaerobic respiration, fermentation, aerobic/anaerobic chemolithotrophy, oxygenic/anoxygenic photosynthesis), predict the dominant metabolism and explain why you expect this metabolism to be most abundant.

(d) Could other metabolisms be present? If yes, explain what other metabolisms are present and why they are present. If no, explain why other metabolisms are not present.

Sandra and Steven are expecting their first child. Each have one female sibling who is affected with PKU (Phenylketonurea) and no other family history of the disorder is known on either side. They ask what their risk is of having an affected child. What do you tell them? A) They must both be heterozygotes so their risk of having an affected child is 25%.

B) There is a 50% chance they are heterozygous carriers so they should get genetic testing.

C) Since neither one of them is affected, they are not at risk of having an affected child.

D) You can't give them any firm answers because you don't know their genotypes.

E) Since this disorder is an autosomal recessive no one in the next generation will have the disease.
