76. Which of the following choices is not an example of an adaptation?
A. Nocturnal animal species have large eyes.
B. One member of a wolf litter is born with shorter legs than its siblings.
C. The pattern of leopard fur makes it hard to see them in tall grass.
D. Bullfrog calls can be heard by potential mates hundreds of meters away.

B

Explanation:

The wolf with shorter legs would not be an adaptation but more of a birth defect as a wolf with short legs would be at a disadvantage.

a: 45.9 meters

b: 4.29 seconds

step-by-step explanation:

a: h(t)=1/2(-9.8)(3)^2+0(3)+90

h(t)=-4.9(3)^2+90

h(t)=-44.1+90

h(t)=45.9 meters

b: 0=1/2(-9.8)(t^2)+0t+90

0=-4.9t^2+90

-90=-4.9t^2

18.37=t^2

t=4.29 seconds

in the second question, the numbers aren't exact, but they're a close approximation.
