It's been a long time since I wrote something here. We've learned about sickle cell anemia and malaria diseases this week, and these two diseases have a connection. This is an example of correlation.
Here is a video which shows an ordinary day of red blood cells:) You will have fun!
Sickle cell anemia provides a protection against malaria. Sickle cell anemia occurs when an offspring inherit a normal hemoglobin from one parent and a sickle hemoglobin from another. As we all learned from the video, red blood cells are oxygen carriers in our body, so sickle cell anemia causes so much pain for people. However, sickle cell anemia is an advantageous thing for malaria. This is an act of natural selection on the genetic resistance to malaria.
I will post some photos which will be helpful to have some extra information about malaria and sickle cell anemia.
This is the mosquito which carries malaria disease.
Here you can see the difference between normal rel blood cells and the ones with anemia.
Here is the symptoms of malaria.
Finally, it is the cycle of malaria.
Have a nice week of IB my dear friends :)
Aylin, photos you have posted are very useful to understand sickle cell anemia and malaria. I agree with you about your ideas. You wrote it is correlation. But I think it will be better if you add with causation or without causation.
