Question 1 A)What causes coral bleaching?(1 point) Responses High water temperatures boil coral polyps, causing them to turn white in color. High water temperatures boil coral polyps, causing them to turn white in color. Water acidity causes coral polyps to lose their photosynthetic abilities, causing them to turn white in color. Water acidity causes coral polyps to lose their photosynthetic abilities, causing them to turn white in color. High water temperatures and water acidity cause coral polyps to expel algae, causing them to turn white in color. High water temperatures and water acidity cause coral polyps to expel algae, causing them to turn white in color. Water acidity and high water temperatures make coral polyps more prone to infection, causing them to turn white in color. Water acidity and high water temperatures make coral polyps more prone to infection, causing them to turn white in color. Question 2 A)What causes ocean acidification?(1 point) Responses Acidic carbon dioxide dissolves in water, lowering the water’s pH. Acidic carbon dioxide dissolves in water, lowering the water’s pH. Acidic oxygen dissolves in water, raising the water’s pH. Acidic oxygen dissolves in water, raising the water’s pH. Acidic oxygen dissolves in water, lowering the water’s pH. Acidic oxygen dissolves in water, lowering the water’s pH. Acidic carbon dioxide dissolves in water, raising the water’s pH. Acidic carbon dioxide dissolves in water, raising the water’s pH. Question 3 A)There is a history of global temperatures changing, but why is this change different?(1 point) Responses The Earth is getting cooler everywhere instead of warmer. The Earth is getting cooler everywhere instead of warmer. This shift in temperature is happening more quickly. This shift in temperature is happening more quickly. It is not different; this is a regular shift in temperature. It is not different; this is a regular shift in temperature. There are more species on the planet this time. There are more species on the planet this time. Question 4 A)Which is the least likely reason that a seal needs ice cover?(1 point) Responses to reproduce to reproduce to get in and out of water to get in and out of water to consume prey to consume prey to protect itself from the sun to protect itself from the sun Question 5 A)Coral bleaching affects(1 point) Responses the temperature of the water. the temperature of the water. the acidity of the water. the acidity of the water. the color of the water. the color of the water. the biodiversity of the water.
