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