Question

the researchers continued another round of experiments in which they tested cool - pool corals for their ability to acclimatize to higher temperatures. they found that cool - pool corals could resist bleaching after prolonged exposure to warm temperatures. which is a new question that could be posed based on this information that would carry the investigation to the next level? which genes are expressed in warm - pool corals, but not expressed in cool - pool corals? which genes are present in warm - pool corals, but absent in cool - pool corals? how does changing other environmental conditions such as ph or salt concentration affect bleaching of cool - pool corals? how do warm - pool corals change when placed in environments with cool temperatures?

Explanation:

The original experiment focused on cool - pool corals' ability to acclimatize to higher temperatures and resist bleaching. A logical next - step question would be to explore how other environmental factors affect the bleaching of cool - pool corals. The first two options are more about genetic differences between warm - pool and cool - pool corals, which is a different line of inquiry. The fourth option is about warm - pool corals in cool environments, not directly related to the follow - up on cool - pool corals' bleaching under different conditions.

Answer:

How does changing other environmental conditions such as pH or salt concentration affect bleaching of cool - pool corals?
