How does global climate change impact coral growth? (4 points)
Global climate change does not impact coral growth.
Climate change decreases the overall temperature of the ocean, preventing coral growth due to the lack of acidic waters.
Greenhouse gases trap solar radiation, which decreases the temperature of the ocean, causing algae to bloom and prevent coral growth.
Greenhouse gases trap solar radiation, which raises the temperature of the oceans, preventing algae growth that is needed for coral growth.
Climate change impacts coral growth through a rise in the temperature of the oceans which limits the growth of algae.
Climate change and coralsClimate change is brought about by a rise in the global temperature as a result of an increase in the concentration of greenhouse gases. The gases trap reflected solar radiation and cause an increase in the temperature of the globe.
An increase in the temperature of the globe also causes an increase in the temperature of the various oceans of the world. Thus, the growth of algae which are the major components of coral reefs is impacted negatively.

This type of blood cell is not a type of white blood cell is C. Platelet.
What is a platelet?Platelets are not a type of white blood cell. They are actually small, colorless cell fragments that are involved in the clotting process of blood. White blood cells, on the other hand, include various types such as lymphocytes, neutrophils, and macrophages, which play important roles in the immune response and defense against infections.
Platelets, also known as thrombocytes, are small cell fragments that circulate in the blood. They are formed in the bone marrow along with other blood cells. Platelets play a crucial role in hemostasis, which is the process of blood clotting to prevent excessive bleeding.
When there is an injury or damage to blood vessels, platelets are activated and aggregate at the site of injury. They form a plug to seal the damaged blood vessel and initiate the clotting cascade, which leads to the formation of a blood clot.
The correct answer is C. Platelet.
