Answer:
D. Ecosystem
Explanation:
The living beings and the non-living conditions of a region interact with each other. They together make an ecosystem. In the given study, the aim was to restore the above-ground vegetation of the region. The "above ground vegetation" of the region is part of its biotic factors. The "below ground soil" is a component of the abiotic factors of the region. Since the study focused on both biotic and abiotic factors of the region, it focused on the ecosystem.
Answer:
The duplication of a cluster of four Hox genes is equally likely as the duplication of a single Hox gene.
Explanation:
This comes from the definition of the parsimony principle, which is the action of choosing the simplest scientific explanation fitting the given evidence, meaning that all other elements are equal when evaluating the hypothesis. In biology the best hypothesis is the one that requires the fewest evolutionary changes.
Since three independent duplications of an individual Hox gene is in evolutionary terms, more complex than a single duplication or a cluster, then that hypothesis would be the most parsimonious.

Answer:
About composition of water and organisms that lives there.
Explanation:
scientists might be able to learn about the composition of seawater that was present millions of years ago if we study those stones that comes in contact to that ancient seawater because the traces of particles still present on it. This study provides valuable information about ancient times of earth and its natural resources. These rocks also provides animals that were present in that sea water at that time.
