They are Holozoic or parasitic.
Following are the statements:
1. Main phagocytes in circulation
2. Like eosinophils, they are involved in inflammation and allergic reactions
3. Phagocytic cells that leave circulation and differentiate into macrophages
4. Display no antigen specificity but are active against tumor and virally infected cells
Answer:
1. Neutrophils
2. Basophils
3. Monocytes
4. Natural killer cells
Explanation:
Neutrophils can be described as the most abundant type of white blood cells. They make up to 55%- 75% of the immune system.
Basophils can be described as white blood cells which are made in the bone marrow.
Monocytes can be described as white blood cells which are the largest and differentiate into macrophages and myeloid lineage dendritic cells.
Natural killer cells can be described as white blood cells which play a role in providing innate immunity.
Answer:
Since sickle cell disease is a disorder with an autosomal dominant inheritance pattern, and in light of the lack of data, it could be said that the only way for Pat and Tracy to have a child with sickle cell disease is for both of them to be healthy carriers of the gene, with a 25% probability.
Explanation:
Considering that both Pat and Tracy each have a sibling with a sickle cell trait and that both they and their parents are healthy, it must be assumed that some of their parents are healthy carriers:
- Pat and Tracy do not have sickle cell trait. In this case, there is no chance that they will have a child with sickle cell disease.
- Either Pat or Tracy has the trait, but the other does not. It is possible that at least one of their children is a healthy carrier.
- If both Tracy and Pat have sickle cell trait, the chances of having a child with sickle cell disease are:
Alelles R r
R RR Rr
r Rr rr
RR: healthy (25%).
Rr: healthy carrier (50%).
rr: sickle cell disease (25%).
<em>If Pat and Tracy are healthy carriers of the gene that determines sickle cell disease, the chance of having a child with the disease is 25%</em>.
