The similarity just lies in the structure. DNA is double-stranded, however it is twisted/helical, while the ladder does not twist. However, other than that, they are quite similar. The 2 strands (5' -> 3' and 3' -> 5') of DNA serve as the 2 vertical sides of the ladder. The base pairs of DNA are what connect the two strands together. So, in terms of the ladder, think of the steps of the ladder as the base pairs. Think each step as consisting of 2 entities joining together to make 1 big step. For example, think of a step having 2 halves down the middle. 1 half would be a guanine (base) and the other half would be a cytosine (base). Guanine is connected to the 5' --> 3' strand (Left vertical side of ladder) while the Cytosine is connected to the 3' --> 5' strand (right vertical side of ladder). These two come together at one of their ends and base pair, which appears to look like the steps on a ladder.

OPTIONS:
a. Bear populations would decline. b. Riparian vegetation would decline. c. Elk populations would decline.
Answer:
c. Elk populations would decline.
Explanation:
The gray wolf can be regarded as a keystone predatory species. The absence or decrease of the population of a keystone predator in an ecosystem largely has a negative impact on the balance of the ecosystem, as well as the population of other organisms in that ecosystem.
In the Yellowstone ecosystem, Elk population is controlled by the gray wolf, as they are hunted down by the gray wolf. As stated in the question, these elks that are being hunted by gray wolf, their carcasses serve as sources of food for the ravens, bears, and the eagles. This means, the presence of wolf in the ecosystem would make enough food available for these animals as their population increases.
What to be expected as the gray wolf is returned is that, the population of elk would decline, since gray wolf would hunt them down. Also, since elk population feed heavily on riparian vegetation, these vegetation would increase rather than decline.
