A particular species of seabird has a mutation in the gene pool that gives it a bigger beak. Individuals with this mutation can more easily break open clams and other mollusks for food. They can also defend themselves better against predators. Over time, most of the organisms in the population have big beaks. What’s this an example of?

Answer:

Natural selection

Explanation:

Organisms with favorable traits (in this case big beaks) have a higher chance of survival than organisms with least favorable traits (small beaks). These organisms will survive, reproduce and and pass on their traits to the following generation, allowing for the organisms to adapt to their environment over time.

This experimental data confirms the role of carbon dioxide in photosynthesis. Hence the correct option is d.

The experimental data supports the conclusion that the presence of carbon dioxide is crucial for photosynthesis. In Plant 1, where sodium hydrogen carbonate was added, carbon dioxide was released slowly due to its decomposition. This availability of carbon dioxide likely facilitated the process of photosynthesis, as evidenced by the positive starch test result in leaf 1.

On the other hand, in Plant 2, where soda lime was added, which absorbs carbon dioxide, the absence of starch in leaf 2 suggests a lack of this vital gas needed for photosynthesis. This underscores the importance of carbon dioxide in the photosynthetic process, confirming that it is a key factor for the synthesis of starch and other organic compounds in plants. Hence the correct option is d.
