Final answer:
If 'K' is selected in terms of ecological strategies, she must select 'b. K-selected' which relates to species with stable populations in equilibrium with the environment. In the context of chemistry, 'K' refers to an equilibrium constant where selecting 'K' suggests favoring a system where products are favored, assuming K's value is greater than 1.
Step-by-step explanation:
When asked about what must be selected if 'K' is selected, this references ecological strategies for species survival, specifically r-selected and K-selected species. The term K-selected refers to species that have stable populations close to the carrying capacity of their environment, which is represented by the variable 'K'. Therefore, if 'K' is selected, it is most likely referencing a K-selected species, meaning that the species is adapted to stable environments and tends to produce fewer offspring with higher survival rates. In another context, specifically chemistry, 'K' may refer to the equilibrium constant of a chemical reaction. If the value of K is greater than 1, this implies that the products are favored under the equilibrium condition. When it is said 'If she selects K', this could also refer to choosing a system where products of a reaction are favored if the given value of the equilibrium constant, 'K', is greater than 1. Without additional context to indicate whether the topic is species survival strategies or chemical reactions, one cannot determine the exact nature of the 'K' referred to in the question. Therefore, based on the provided scenarios, if 'K' is selected within the realm of biology, she must select b. K-selected. If 'K' relates to chemistry, selecting 'K' means preferring a reaction's products over its reactants assuming K is greater than 1
