Describe the pros and cons of the treatments used for each of the sickle cell anemia patients investigated in this activity.
notka56 [123]
Sickle cell anemia is caused by an abnormal hemoglobin in red blood cells. hemoglobin is the red pigment found in red blood cells for carrying oxygen.The abnormality arises from a genetic mutation in the DNA gene that codes for the  beta chain of the protein called globin of which hemoglobin is made of.In the beta chain, the sixth amino acid called glutamine is replaced by another one called valine.<span>This one change in the amino acids cause the hemoglobin protein  to behave abnormally, causing  red blood cells to lose their normal spherical shape and become bent like a sickle, hence the name "sickle cell" anemia</span>

Fishes and bottom dwelling worms cope with the fluctuating salinity within estuaries over the tidal cycle with the use of transport system such as active and passive transport.

<h3>How active and passive transport system are used?</h3>

In salty water, fish and other marine organisms used active transport in which energy is used to remove salts from the body of these marine organisms because excess salts are harmful for them.

So we can conclude that Fishes use transport system such as active and passive transport to cope with the fluctuation of salt concentration.
