Can the italicized portion of the problem be explained? I understand up until the 0.015 moles of protonated acetic acid remained and I understand the HH portion of the problem after but I would like some clarity on how this number was concluded.

2. The following question has two parts.
a) What is the final pH of a solution obtained by mixing 250 ml of 0.3 M acetic acid with 300 ml

of 0.2 M KOH? (pKb of acetate = 9.24). (Show your work!)

Moles of acetic acid = 0.25 l X 0.3 M = 0.075 moles
Adding 0.3 l X 0.2 M = 0.06 moles of OH- to this solution will convert 0.06 moles of acetic

acid to 0.06 moles of acetate, 0.015 moles of protonated acetic acid will remain. pKa = 14 - pKb = 14 - 9.24 = 4.76

pH = pKa + log [CH3CO2-][CH3CO2H]

= 4.76 + log 0.06 moles / 0.55 l 0.015 moles / 0.55 l

= 4.76 + log 0.06 moles0.015 moles

= 5.36

pH = 5.36

What direct evidence do scholars present for behavioral links between gorillas/chimpanzees and humans. Give at least four examples.  

What kinds of advantages, in terms of evolutionary fitness, do cooperative behaviors provide among different species of non human primates, and under what selective pressures would behaviors such as altruism (toward kin and nonkin) be likely to evolve?

Why has being social been selected for (called a prosocial behavioral strategy) among some primates, including humans? Come up with a reason for its adaptation.

You are at a dinner table and your uncle says, “If evolution were true, then why do we still have monkeys?” After taking this class how would you answer?

if you suspect a contaminant in one of your different media tubes (slant/deep/broth), what should you do to confirm that there is a contaminant?

Scientists recently discovered that elephants have 40 copies of the p53 gene, while humans have two copies (one from our biological mother and one from our biological father).

Use the language of biology to explain how this discovery could explain why so few elephants die from cancer.

A) Please explain the difference between negative and positive feedback loops as it applies to climate change. Give an example of each.

B) Bird migrations (to breeding areas) are often linked to day length which has changed extremely slowly for millions of years. Temperatures have change very rapidly recently and now insects are hatching up to two weeks earlier than they used to. Why is this a problem for birds that depend on those insects for food for their chicks?

What activates pyruvate kinase, what is this activation called, and why does it occur?

A common clinical manifestation of pulmonary infections is pulmonary edema. Explain what leads to the accumulation of fluid in the alveolar spaces and explain how pulmonary edema impairs lung function.

Does phosphorylation of a signaling protein by an upstream kinase represent a signaling input or output? Explain.

describe the variation that exists among protists with respect to their cell surface, motility, nutrition and cellular organization

Which type of epitope(s) are recognized by the B cell receptor?

a. Linear epitopes.

b. Conformational epitopes.

c. Embedded epitopes.

d. Both a and b.

The Omo remains and mitochondrial DNA analysis suggest that the earliest humans first evolved approximately:

Discuss in detail (not just enumerate) at least three factors that contribute to the current worldwide expansion of vector-transmitted diseases.

Explain in some detail (not just enumerate) at least FOUR factors that contribute to healthcare-associated infections and four strategies to reduce their incidence.

Define and explain the terms genotype and phenotype. Give an example of a genotype and phenotype; indicate how the genotype and phenotype are related. Define and explain what an allele is. Give an example of an allele and indicate how alleles are related to a genotype.

If a sequence of one strand of DNA is ATTGCTCG, what is the complementary sequence?

explain how the Hershey-Chase experiment conclusively proved that DNA and not protein was the genetic material?
