A lab technician took a fecal sample and carried out the following dilutions: 1. Transferred 0.1 mL from the fecal sample to 9.9 mL saline in tube B 2. Transferred 0.1mL from A to 9.9 mL saline in tube B 3. Transferred 0.1 mL from B to 9.9 mL saline in tube C 4. Transferred 0.1 mL from tube C to an agar plate 5. Counted 47 colonies on plate Questions: 1. What is the serial dilution in A? 2. What is the serial dilution in B? 3. What is the serial dilution in C? 4. What is the Concentration of Fecal Cells in Tube C? 5. What is the concentration of the original, undiluted Fecal sample?

The following experiment is carried out in a physiology lab. Red blood cells are placed in different solutions: distilled water, 0.45% saline, 0.9% saline, 5% urea, and 5% glucose. The molecular mass for each molecule is given: NaCl = 58.44 gm/mole; urea = 60.06 gm/mole; glucose = 180.16 gm/mole. For each of the solutions used, calculate the osmolarity. To do this, you will need to convert solutions given in percents to osmolarity. A 0.45% saline solution has 0.45 gm/100 mL...

Dihybrid crosses of (virtual) fruit flies (Drosophila melanogaster) were carried out at the computer lab at this course. The mutant alleles studied were “vestigial wing” (vg) and “ebony body” (eb). The mutant P‐generation flies were homozygous recessive at both studied loci. The wild type alleles were homozygous dominant at both loci. The loci for vestigial wing and ebony body are located at separate chromosomes. Show the Punnett crosses from the P‐generation to the F1‐generation of mutant and wild type flies,...

1. To identify a diatomic gas (X2 ), a researcher carried out the following experiment: She weighed an empty 4.8-L bulb, then filled it with the gas at 1.60 atm and 29.0 ∘C and weighed it again. The difference in mass was 8.7 g . Identify the gas. 2.Aerosol cans carry clear warnings against incineration because of the high pressures that can develop upon heating. Suppose that a can contains a residual amount of gas at a pressure of 745...
