what type of disorder is sickle cell anemia
It's an "Inherited Blood disorder"
Explanation:
what is "Sickle cell anaemia"?
A group of disorders that cause red blood cells to become misshapen and break down.
With sickle cell disease, an inherited group of disorders, red blood cells contort into a sickle shape.
Sickle cell disease is caused by inheriting the sickle cell gene.
The sickle cells die early, which causes a constant shortage of red blood cells. Also, when they travel through small blood vessels, they get stuck and clog the blood flow. This can cause pain and other serious problems such infection, acute chest syndrome and stroke.
Explanation in brief:
Anemia has three main causes:
blood loss, lack of red blood cell production, and high rates of red blood cell destruction.

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.

Changes in ecosystems can be attributed to natural causes, such as natural disasters, seasonal variations in climate, currents, and tidal activity. Many of these changes can affect the amount of food resources available in an ecosystem. Research one natural change that currently affects or could affect the aquatic ecosystem you chose. Use your food web model to explain how this change can affect the competition of food resources in your aquatic ecosystem.
The reduction of food sources results in the competition of food resources in the aquatic ecosystem.
How natural disaster can leads to the competition?Severe storm occurs in the water which adversely affected the aquatic ecosystem. This change can affect the competition of food resources in your aquatic ecosystem because the food on which the aquatic animals feed is destroyed by the storm. So less food is available for the organisms which leads to competition between organisms.
So we can conclude that the reduction of food sources results in the competition of food resources in the aquatic ecosystem.
