AA DD individuals were crossed to aa dd individuals. The F1 generation was then testcrossed to aa dd individuals. The resulting individuals had the following genotypes: 903 individuals with the genotype Aa Dd, 897 individuals with the genotype aa dd, 98 individuals with the genotype Aa dd, 102 individuals with the genotype aa Dd.

1. Are the genes (A and D) on the same chromosome or different chromosomes? (Calculate the expected number of progeny if they were on different chromosomes and compare.)

A. Same chromosomes

B. Different chromosomes

C. Can't be determined

2. If A and D are on the same chromosome, how far apart are they in Map Units. (Answer in a number - without units, if they are not on the same chromosome, answer 0).

7. You have a hash function that takes the binary bits of a number, divides it up into blocks of 4 bits and then XORs the blocks together. So for example, if we have 4 blocks, block X0, X1, X2 and X3, the result of the 4-bit block hash would be X0 XOR X1 XOR X2 XOR X3. For example, the hash of "011011001010" would be "0110" XOR "1100" XOR "1010". Demonstrate that this is a poor hash function by showing me a hash collision using this function and two different input strings of at least 8 bits.

1) When 0.119 g of Zn(s) is combined with enough HCl to make 51.6 mL of solution in a coffee-cup calorimeter, all of the zinc reacts, raising the temperature of the solution from 22.4 ∘C to 23.9 ∘C. Find ΔHrxn for this reaction as written. (Use 1.0 g/mL for the density of the solution and 4.18 J/g⋅∘C as the specific heat capacity.)

2)Calculate ΔHrxn for the following reaction:

CaO(s)+CO2(g)→CaCO3(s)

Use the following reactions and given ΔH values:

Ca(s)+CO2(g)+12O2(g)→CaCO3(s), ΔH= -812.8 kJ
2Ca(s)+O2(g)→2CaO(s), ΔH= -1269.8 kJ

Please give explanation.

Consider the titration of 100.0 mL of 0.200 M CH3NH2 by 0.100 M HCl.
For each volume of HCl added, decide which of the components is a major species after the HCl has reacted completely.
Kb for CH3NH2 = 4.4 x 10-4.

200.00 mL HCL added   


yes no  H+
yes no  H2O
yes no  Cl-
yes no  CH3NH2
yes no  CH3NH3+

300.00 mL HCL added:

yes no  H+
yes no  H2O
yes no  Cl-
yes no  CH3NH2
yes no  CH3NH3+

Calculate the pH at the equivalence point for this titration?

At what volume of HCl added in this titration does the pH = 10.64? Express your answer in mL and include the units in your answer?

1. A 70 kg adult male is exposed to 0.001 ppmv of vinyl chloride (C2H3Cl) in the air at his workplace. Note: this is far below the permissible exposure limit set by OSHA (1 ppmv).

a) Calculate this man’s lifetime cancer risk from this inhalation exposure. Assume temperature and pressure conditions of 20°C and 1 atm. Use exposure factors given in Table 6.14, and the slope factor = 0.295 (mg/kg ・ day)^-1.

b) If this man wants to limit his lifetime cancer risk from inhalation exposure to vinyl chloride to 10^-6, how many years could you work at this job?
