Answer:
Haemoglobin (Hb) is a protein present in red blood cells that transports oxygen and gives blood its dark/vivid red color. The amount of haemoglobin in the blood varies from person to person. Men's levels are often greater than women's. This is scientifically proven however, it is often but not all the time.
Answer:The reason for this is because fungi and their host are eukaryotic and in treatment of fungal infections drug used can also affect their host.
Explanation:
Antifungal drugs are drugs used in the treatment of fungal infections and so are antibiotics and antiviral drugs used to treat bacterial infections and viral infections respectively.
Fungi and their host are both eukaryotic and this make them closely related. They attack by colonizing and destroying the tissues of the animal host. When treating infections caused by fungi, the compounds used to kill fungi also harm the animal host because of the eukaryotic property they both possessed, this therefore set limitations to antifungal drugs. Unlike fungi, bacteria attack prokaryotic cell and also bacterial infections are systematic not superficial or topical like fungal infections.
Sickle cell is a disorder that affects the
molecules in the red blood cells, particularly the hemoglobin. The hemoglobin
is the molecule responsible for transporting oxygen throughout the body. When a
person has sickle cell anemia, the red blood cells are distorted crescent
shapes that do not travel in the bloodstream properly and efficiently. As a
result, this disorder hampers the distribution of oxygen throughout the body.

Anemia is the major characteristic of sickle cell
disorder. A person with sickle cell anemia has low number of red blood cells
that usually begin in early childhood. A person who is experiencing Sickle Cell
Anemia will have multiple and repeated infections, and periodic episodes of
pain. The severity of this condition varies from person to person but is common
in African descents. </span>
