Joe is breeding cockroaches in his dorm room. he finds that the average wing length in his population of cockroaches is 4 cm. he chooses the six cockroaches that have the largest wings; the average wing length among these selected cockroaches is 10 cm. joe interbreeds these selected cockroaches. from earlier studies, he knows that the narrow-sense heritability for wing length in his population of cockroaches is 0.6. a. calculate the selection differential and expected response to selection for wing length in these cockroaches. b. what should be the average wing length of the progeny of the selected cockroaches?

Protein and polypeptide sequences can be determined by first partially hydrolyzing the protein or polypeptide followed by amino acid sequencing of the fragment pieces using the chemical degradation process known as edman degradation. determine the sequence of the initial (18-amino acid) polypeptide that produces the following five partial sequences after hydrolysis and edman degradation.

Based on the observations provided, what is the relationship of current diabetes medication use and the use of extract from ginko biloba? a) the anti-inflammatory properties of ginko biloba extract are beneficial in treating t2d separate from the benefits of other therapies. b) the overall abundance of ginko biloba makes this extract an attractive joint therapy for existing medications that are used to treat t2d. c) the side effects of t2d medications have resulted in the need for different therapies to treat t2d like the use of ginko biloba extract. d) clinical outcomes from the use of current t2d medications may be improved through the use of cost-effective ginko biloba extract treatment. e) previous studies with ginko biloba and current t2d medications do not support the use of these treatments as effective against t2d in patients.
