Answer:

Warmer water temperatures can result in coral bleaching. When water is too warm, corals will expel the algae (zooxanthellae) living in their tissues causing the coral to turn completely white. This is called coral bleaching. When a coral bleaches, it is not dead

Answer/Explanation: The main cause of coral bleaching is heat stress resulting from high sea temperatures. Temperature increases of only one degree celsius for only four weeks can trigger bleaching events. If this temperatures persist longer periods (eight weeks or more) corals begin to die.

Orcas are endangered whales. Only about 80 individuals remain off the 1 point
pantera1 [17]

Answer:

This situation is an example of opportunity cost.

Explanation:

Opportunity cost is a term widely used in the economy, but it can be applied to other areas. This term refers to a choice that must be made between two factors. However, choosing one factor promotes the renouncement of opportunities that the other factor would provide.

An example of this can be easily seen in the question above, where in order to increase the availability of food for orcas and decrease the threat of extinction of this animal, it will be necessary to remove the d*ms from the region. However, if the d*ms in the region are removed, it will not be possible to offer low-cost energy to the population, which can negatively influence the local economy.
