The answer is B: protects seeds
When studying a complex biological phenomenon, it is required to look at the workings of the various systems associated with it. The research is a top-down approach of getting down to the very detail of the cells and molecules taking part in it. Example, a person finds it difficult to digest milk and vomits it on ingestion. As we go a level down, we identify the systems getting affected by the milk. Then, further down, the cells that take in digesting the milk are identified. The enzymes that break down the substances in the milk are identified. The gene regulation of this enzyme (lactase) is studied to check its regulation. This work of doing a top-down approach to find the signalling pathway within the cells to identify the problem with the working of lactase to digest milk, is a necessary approach.
The answer to this is NATURAL SELECTION. From the given scenario above, this is classified to be a natural selection because of the changes made by the individuals in order to adapt the presence of this fungal disease. When we say natural selection, this is the ability of an organism to adapt to a certain environment in order to survive. This is according to Charles Darwin which has been the source for the study of evolution.
This is an example of a life of engagement principle. Pleasure, engagement, and meaning are some of the most important factors that make up societal purpose and behavior. If a person experiences such feelings towards a situation then there must be something that she can do to correct it. Either Ashley needs to live the place or find a better place where she can be happy.
