Suppose a potential biological control agent was found to attack an indigenous Drosophila species in California, in quarantine laboratory screening work. The US Fish and Wildlife Service oppose release of the biocontrol agent because of this, suggesting that the risks are too great in terms of impacting an endemic species. What risk assessment options could you employ in further work to determine whether the biocontrol agent is safe to release? How would you explain the measurement of risk to the FWS and the public in general?

A 10-year-old girl was brought to an outpatient clinic because she complained of sore throat and a lump in her neck. On examination, she was observed to have a tonsillar abscess, swollen glands, and widespread bruising in the extremities. She also had a low-grade fever. She was treated with antibiotics and released, but she failed to progress over the next 2 days. Hematology laboratory tests revealed a WBC of 8.0 x 10^9/L, a hematocrit of 28%, and a platelet count of 10 x 10^12/L peripheral blood differential count revealed 3 band neutrophils, 25 segmented neutrophils, 8 lymphocytes, 1 monocyte, and 63 blasts.
The patient’s parents were contacted, and the girl was immediately admitted to the hospital. A bone marrow examination was performed and revealed an infiltration of blast cells in the marrow.
Immunophenotyping was performed on the bone marrow cells. The results show the cells have CD 11b, CD 13, CD 33, and CD15 markers.
1. Why are the hematocrit and platelet count decreased?
2. What is immunophenotyping and why is it an important test?
3. What is the most likely diagnosis based on these test results?
4. How would the results differ in the immunophenotying of the cells had CD 10, CD 19, CD 20 and CD 22 markers?

We are now going to count the amount of ATPs that fat, sugar, and ethanol can produce per equivalent carbons. In this case, 12 carbons. We will compare sucrose, lauric acid, and six molecules of ethanol.Sucrose is cleaved to glucose and fructose by sucrase.How many ATP is produced from the COMPLETE oxidation of sucrose in the muscle. Assume 1NADH=3 ATP, 1FADH2=2ATP and 1 GTP= 1ATP

A dominant gene, b+, is responsible for the wild-type body color of Drosophila. It’s recessive allele, b, produces black body color. A testcross of a wild-type female produced 52 black flies and 58 wild-type flies in the F1 generation.
a. What are the genotypes of the parents?
b. What are the genotypes of the F1 generation?
c. If the wild-type F1 females are crossed with their black F1 brothers, what genotypic and phenotypic ratios would be expected in their F2 offspring?
