Research and write an essay about the "prague Spring." What did it hope to achieve, and why was it unsuccessful? Be sure to include a bibliography of the sources you consulted.

Which phrase best defines “annotated bibliography”?

A. a bibliography that is typed on expensive paper with a specified font

B. a summary and evaluation of each potential source for a research project

C. a handwritten summary of the location of research sources

D. a day-by-day log of all bibliographic sources for a research project

Although we have labeled the second example a “final” draft, we know that our writing can always be improved. What would you suggest Stephanie do to make this essay even better?

a. What is the first step in scientific research? b. What is a hypothesis and how is it often worded? c. Explain the importance of replication in scientific research.

An annotated bibliography is a tool for tracking and giving credit to sources used for your research. Entries typically consist of two parts: a citation which follows the guidelines of a style manual-such as MLA - for the source, and an annotation (a brief summary of and commentary about the source). Examine the model entry below. Then, mark the text to identify the key elements of an annotated bibliography entry: information and details, evaluation of usefulness, and source description.

Use the following template to compile annotated entry drafts for each of your required sources. Once you have completed your annotated entries, compile a complete annotated bibliography as a group. The bibliography should be in alphabetical order. You will also need to complete a source evaluation sheet for each online resource you use.

An annotated bibliography provides both the citation information and a brief explanation or summary of the source as well. On the back (lined) side of your notecard, write an annotation. Include the following:

• A brief summary of the content of the site
• An evaluation of the site's accuracy, validity, usefulness, etc.
• How this site helped you answer your research question

To practice note-taking and generating a bibliography entry, complete the research card using information from "How the Brain Reacts." (Source Citation: How can this source help you to support your argument? What makes this source credible?)

Explain the importance of each of the following terms. Red Army, supra.

Use the Internet to explore the most recent archaeological finds of prehistoric humans not mentioned in the text. Present this information in a short essay. Be sure to use authoritative sources and be sure to cite your sources in your bibliography.

Transform each by making the change of variable i=k+1.

$$\prod _ { k = 1 } ^ { n } \frac { k } { k ^ { 2 } + 4 }$$

What is the best description of the thesis statement in graduate writing?

How did the period of detente between the United States and the Soviet Union lead to a relaxation of authoritarian rule?

In 1927 , the ophthalmologist George Waaler tested 9049 schoolboys in Oslo, Norway, for red-green color blindness and found 8324 of them to be normal and 725 to be color blind. He also tested 9072 schoolgirls and found 9032 that had normal color vision while 40 were color blind.

a. Assuming that the same sex-linked recessive allele $c$ causes all forms of red-green color blindness, calculate the allele frequencies of $c$ and $C$ (the allele for normal vision) from the data for the schoolboys. (Hint: Refer to your answer to Problem 12a.)

b. Does Waaler's sample demonstrate Hardy-Weinberg equilibrium for alleles of this gene? Explain your answer by describing observations that are either consistent or inconsistent with this hypothesis. On closer analysis of these schoolchildren, Waaler found that there was actually more than one $c$ allele causing color blindness in his sample: one kind for the prot type $\left(c^p\right)$ and one for the deuter type $\left(c^d\right)$. (Protanopia and deuteranopia are slightly different forms of red-green color blindness.) Importantly, some of the apparently normal females in Waaler's studies were probably of genotype $c^p / c^d$. Through further analysis of the 40 color-blind females, he found that 3 were prot $\left(c^p / c^p\right)$, and 37 were deuter $\left(c^d / c^d\right)$.

c. Based on this new information, what are the frequencies of the $c^p, c^d$, and $C$ alleles in the population examined by Waaler? Calculate these values as if the frequencies obey the Hardy-Weinberg equilibrium. (Note: Again, refer to your answer to Problem 12a.)

d. Calculate the frequencies of all genotypes expected among men and women if the population is at equilibrium.

e. Do these results make it more likely or less likely that the population in Oslo is indeed at equilibrium for red-green color blindness? Explain your reasoning.
