question 99

Short Answer

TABLE 8-10
A university wanted to find out the percentage of students who felt comfortable reporting cheating by their fellow students. A survey of 2,800 students was conducted and the students were asked if they felt comfortable reporting cheating by their fellow students. The results were 1,344 answered "yes" and 1,456 answered "no".
-Referring to Table 8-10, a 99% confidence interval for the proportion of the student population who feel comfortable reporting cheating by their fellow students is from ________ to ________.

Identify various reproductive isolating mechanisms and their significance in evolution.

Explain the significance of Darwin's finches in studying evolution and adaptive radiation.

Distinguish between prezygotic and postzygotic reproductive barriers.

Understand the role of polyploidy in speciation, especially in plants.

Definitions:

Nonsense Mutation

A base-pair substitution mutation that results in an amino acid–specifying codon being changed to a termination (stop) codon; when the abnormal mRNA is translated, the resulting protein is usually shortened and nonfunctional. Compare with missense mutation.

Codon

A sequence of three nucleotides that together form a unit of genetic code in a DNA or RNA molecule, representing a specific amino acid.

Termination Codon

A nucleotide triplet within messenger RNA that signals the end of translation, resulting in the release of the newly synthesized protein.

Anticodon

Three nucleotides in a row create a genetic code unit within a transfer RNA molecule, matching a corresponding codon in messenger RNA.
