A developer proposes to build new houses and roads on land that is now part of Mairead Forest, which is a tract of 120 acres that the county has designated as conservation land. The conservation is home to many native species, including large apex predators.
The developer points out that his proposal would keep the size of forested land at 120 acres. However, much of the forest would be divided into small pieces separated by highways, houses, and lawns. The developer states this solution will protect the natural ecosystem by maintaining the natural biodiversity of the forest.
Based on the information, what is the best response to the developer’s claim?
The claim is likely correct because the native biodiversity will likely remain stable since the size of the forested land would remain the same.
The claim is likely correct because the native biodiversity will likely increase since humans and their pets are entering the region.
The claim is likely not correct because many animal species depend on large areas of land to survive and reproduce.
The claim is likely not correct because the best way to protect the natural ecosystem is to reduce biodiversity.

The mutations will decrease genetic diversity because they will remove disadvantageous traits that would otherwise get passed onto offspring.
The mutations will decrease genetic diversity because they will cause more competition that will eliminate many organisms from the population.
The mutations will increase genetic diversity because they will increase the number of new species that move into the area.
A plant growing in a field produces both thorny and smooth seeds. These seeds are eaten by field mice. When the mice eat the seeds, they break them open to get to the edible parts inside. A researcher counted all of the seeds in one area of the field and tallied whether the seeds were open or closed, and thorny or smooth. The findings are in the table.
Based on the data, will the smooth seeds have greater reproductive success than the thorny seeds?
Yes, because the smooth seeds are better able to protect themselves against being eaten by the mice.
Yes, because there are a greater number of smooth seeds than there are thorny seeds, so the population is larger to start.
No, because the mice eat smooth seeds more often, which suggests being a smooth seed is less advantageous than being a thorny seed.
No, because the smooth seeds are going to be better competitors for open space in the forest due to germinating faster.
