According to Baird et al. (2012), engaging in simple external tasks that allow one’s mind to wander may hinder creative problem solving.

Two genes are 22 map units apart on the same chromosome. A true-breeding GGhh individual is crossed to a true-breeding ggHH individual. The F1 offspring are mated to gghh individuals. If this testcross produces 1000 offspring, how many of them would you expect to be GgHh? 

In eukaryotes, a site within the cell nucleus that is occupied by a single chromosome is a

A researcher conducted crosses between two different strains of Drosophila. When true-breeding flies with singed bristles (s) and normal wings (L) were crossed to true-breeding flies with normal bristles (S) and vestigial wings (l), all F1 offspring had normal wings and normal bristles. The F1 offspring were crossed to flies with singed bristles and vestigial wings. Which F2 offspring is/are nonrecombinant? 

Radial symmetry is seen in a ________.  

Smart Home Designs Inc. is a company that produces high-end “smart home products”. One afternoon, a fire breaks out in their production facility, destroying a critical piece of machinery that produces most of the “smart product’s” circuit boards. Smart Home Designs contacts the manufacturer of the machine, and arranges for expedited shipping of a replacement machine which costs a whopping $10,000. Despite this, the earliest the machine can arrive is in seven days. As a result, Smart Home Designs is unable to manufacture or sell any smart home products for at least one week. The underlined portion of the above scenario is example of what? 

Chargaff’s studies of the base composition revealed that the amount of A equals T and the amount of G equals C. These results were important determining which structural aspect of DNA?

Carl works for FEDEX as a delivery driver. Over the weekend on his days off from work, Carl was playing in an intermural soccer league with his friends. Unfortunately, during the game he tripped and tore his ACL. He was sent to the hospital and treated for his injuries, which cost a total of $10,000. Additionally, Carl will not be able to work his FEDEX job for at least 6 months while he recovers from his knee injury.  The above scenario presents which of the following types of risk for Carl?   I. Personal Risk, specifically Loss of Income II. Personal Risk, specifically Medical Expenses III. Hazard Risk, specifically Personnel Exposure
