write a lab report for this lesson’s lab. be sure that your report:

 includes all major elements of a lab report.

 meets your teacher’s content and format expectations.

 is clearly organized and formatted.

 demonstrates strong scientific reasoning and writing.

while writing, you can revisit previous parts of the lesson by returning to the course map. be sure to refer to the

lab’s student guide, which you can find on the first page of the lab experiment activity. you may also find it

to refer to the remaining pages of this guide, which provide general guidelines for writing lab reports.

To answer this question, researchers studied populations of the dusky salamander (desmognathus ochrophaeus) living on different mountain ranges in the southern appalachian mountains. the researchers tested the reproductive isolation of pairs of salamander populations by leaving one male and one female together and later checking the females for the presence of sperm. four mating combinations were tested for each pair of populations (a and b)—two within the same population (female a with male a and female b with male b) and two between populations (female a with male b and female b with male a). the proportion of successful matings for each mating combination was measured. for example, when all the matings of a particular combination were successful, the researchers gave it a value of 1; when none of the matings were successful, they gave it a value of 0. then the researchers calculated an index of reproductive isolation that ranged from 0 (no isolation) to 2 (full isolation). the reproductive isolation value for two populations is the sum of the proportion of successful matings of each type within populations (aa + bb) minus the sum of the proportion of successful matings of each type between populations (ab + ba). the table provides data for the geographic distances and reproductive isolation values for 27 pairs of dusky salamander populations.

Asea turtle has washed up on a remote section of a beach. this known as a stranding occurs when a dead,sick or injured sea turtle washed up on the shoreline. which statment best explain why stranding should be reported immediately to local authorities
