Answer 1

Ocean acidification is intensified by warming sea surface temperatures is true, all of the above contribute to reducing available light and/or smothering unbleached corals, making it harder for them to survive

Ocean acidification is intensified by warming sea surface temperatures.The increasing carbon dioxide in the atmosphere due to anthropogenic activity leads to a phenomenon known as ocean acidification.

This phenomenon leads to a decrease in the pH levels of the ocean, making it more acidic. Warming sea surface temperatures intensify this process, exacerbating the negative impact on marine life and ecosystems. As carbon dioxide is absorbed by seawater, the seawater's acidity increases, reducing the pH value of the seawater.

This acidification of seawater can also lead to the depletion of minerals such as calcium and carbonate, which are essential for shell formation and the growth of coral reefs. Therefore, the statement is true.

All of the above contribute to reducing available light and/or smothering unbleached corals, making it harder for them to survive.

Therefore, the answer is option D.

Answer 2

Ocean acidification is intensified by warming sea surface temperatures," is TRUE.

The more carbon dioxide in the atmosphere, the more is absorbed into the ocean, and the more acidic the ocean becomes. Ocean acidification can lead to the decline of marine ecosystems, harming organisms such as oysters and coral reefs. When the pH of seawater drops, it dissolves the calcium carbonate shells of mollusks, plankton, and coral reefs, as well as affects the metabolic processes of fish and other organisms.

Therefore, the given statement, "Ocean acidification is intensified by warming sea surface temperatures," is true.

The following contribute to reducing available light and/or smothering unbleached corals, making it harder for them to survive are: Increased algal blooms.Increased algal blooms cause harm to coral reefs by reducing available light and smothering unbleached corals, making it harder for them to survive. As the oceans become warmer and more acidic, algae blooms are predicted to become more frequent and severe.

Additionally, algae have a variety of toxic effects on corals, such as causing coral disease, suppressing the coral immune system, and exacerbating coral bleaching.

Therefore, the answer is option O Increased algal blooms.

Publishing a policy and standards library depends on the communications tools available within an organization. Some organizations keep documents in Word format and publish them in PDF format. Other organizations use Governance, Risk, and Compliance (GRC), a class of software for supporting policy management and publication.
