The kangaroo rat has a round body with large hind legs and small ears. They are pale tan color and usually have a white spot on their stomachs. Kangaroo rats usually grow to be between 9 and 14 inches long, with most of the length coming fro their tail. Their tail acts a balance point to help them move by hopping on their back legs. The Kangaroo Rat eats only seeds. Kangaroo rats have specialized kidneys which allow them to get rid of waste products without losing water. Kangaroo rats are nocturnal, meaning they move around only at night. Based on the description proveded and the picture, which habitat would the Kangaroo rat likely live in?
A . The desert
B . The rainforest
C . The tundra
D . The grasslands
Based on the information provided about Kangaroo rats, which adaptation would Most Likely help it to survive in that environment?
A . The Kangaroo rats round body
B . The Kangaroo rats small ears
C . The Kangoroo rats specialized kidneys
D . The Kangaroo rats small front legs
If a Kangaroo inherited a trait that did not allow it to see well at night, what would be a likely outcome?
a. The trait would be passed on to future generations of kangaroo rats because it is helpful to the survival of the kangaroo rat.
b. The trait would not be passed on to future generations of kangaroo rats because it is not helpful to the survival of the kangaroo rat.
c. The trait may be passed on the future generations of kangaroo rats because it does not affect the survival of the kangaroo rat.
d. There is no way to know if this trait will be passed on to future generations.

D . All organisms use asexual reproduction.
Looking at the pictuee below, which been seed would you expect to grow the tallest with the most leaves?
