which of the following animals from the arctic tundra are falsely known as \suicidal rodents\?
short - tailed weasel
quoll
lemming
hare

Explanation:

First Question (Permafrost Definition)

• Analyze each option:
• First option: Defines a fjord, not permafrost.
• Second option: Matches the definition of permafrost (permanently frozen subsoil in cold areas).
• Third option: Defines tundra (has permafrost but is a different term).
• Fourth option: Defines taiga, not permafrost.

• Recall arctic tundra animals: Lemmings are falsely known as "suicidal rodents" due to myths about mass migrations. Short - tailed weasel, quoll (not arctic), and hare don't have this misnomer.

Answer:

B. Permanently frozen subsoil, occurring in perennially frigid areas. (Assuming the options are labeled A, B, C, D with the first option as A, second as B, etc.)
