can someone help me on this question please:
27. The tundra is most suitable to a vertebrate that
a. requires nesting sites in tall trees
b. is cold blooded
c. has a green outer skin for camouflage
d. can migrate hundreds of kilometers each summer
i've eliminated A and C from my choices...i'm leaning towards D..?
D. is definitely the answer.
Check these sites about cold-blooded creatures.

I'd choose D, too.
ok, finally a correct answer :)

To determine the correct answer, let's break down the question and consider the characteristics of the tundra. The tundra is a biome characterized by extremely cold temperatures, low vegetation, and a short growing season.
a. The tundra does not have tall trees suitable for nesting sites, so option A can be eliminated.
b. Being cold-blooded means an organism's body temperature is determined by the environment. However, the extreme cold temperatures of the tundra would not be suitable for a cold-blooded vertebrate. Therefore, option B can also be eliminated.
c. The tundra's landscape is dominated by low-lying vegetation and not tall trees. Therefore, an outer green skin for camouflage is not necessary, so option C can be eliminated.
Now let's focus on option D, "can migrate hundreds of kilometers each summer." This characteristic is well-suited to the tundra environment. Many vertebrates that inhabit the tundra, such as caribou, migrate long distances during the summer months to find food and suitable breeding grounds in the short growing season.
Based on the analysis above, option D is indeed the most suitable choice. It aligns with the migratory behavior commonly observed in tundra-dwelling vertebrates.
