Explanation:
The Ames test is a bacteriological technique commonly used to determine if a particular chemical or substance can cause mutations. To achieve this, researchers use bacteria (commonly <em>Salmonella typhimurium</em>) as this bacteria strain is unable to grow in a medium that does not contain histidine (a very important amino acid in the biosynthesis of proteins). If the studied substance is able to cause mutations, bacteria will mutate, and they will be able to grow on that particular media even if they don’t have histidine for their metabolism. Therefore, if there are colonies growing, the chemical being tested is mutagenic.
I hope this clarify your inquiry.

Explanation:
The population of squirrel is decreasing and this can be traced to the environment not being favorable for their growth and development.
Looking at the data generated,
Died from predation =2
Born=4
Immigration=10
Left to find food =3
Died from disease=8
Left to find mate=3
If all the squirrel did not abandon their habitat and they all live there a total of 2+4+10+3+8+3= 30 squirrel would have been present, but given that only 4 were born and that others left for another place the population is reduced to 4 and 26 squirrel gone this has lead to a reduced population.
