What diseases where there in 1066?
The same diseases we have today existed in 1066. With the exception of HIV.
What came from the old world to the New World?
Horses, powder, and diseases came to the new world. This brought not only economic boon, but also hardship at the same time. The horses provided mass transportation, however the diseases plagued the population.
Define crop rotation?
The successive planting of different crops on the same land to improve soil fertility and help control insects and diseases.
Did Soviet Union change their flag after World War 2?
If you mean why did the Hammer and Sickle changed to the tricolor of the Russian Federation (white, red and blue) the answer is because in December of 1991, the ruler of the USSR ended it by resigning from office and giving the power of the army to the next president of the new Russian Federation. The Hammer and Sickle was taken down over Moscow and the new flag was raised of the Russian Federation.
Why were the Incas and other native American societies extremely susceptible to European diseases?
The Incas and other native American societies were extremely susceptible to European diseases because they had never been exposed to the diseases and so had no herd immunity, allowing the disease to spread rapidly and freely. In Europe the many people that had previously had these diseases were immune, and so could not catch it again, giving the Europeans some degree of herd immunity. Once the disease ran out of easily-available nonimmune people, it could no longer spread..
Could the same genetic condition that causes sickle cell anemia can also protect against any other diseases?
A single sickle-cell gene protects against malaria. Two sickle-cell genes produce sickle-cell disease.
How are sickle cell anemia and maleria the same?
They are definitely not the same. If you are looking for an answer to WHY sickle-cell anaemia is BENEFICIAL to those with malaria then follow this link,What_is_the_benefit_of_sickle_cell_anemia_to_Africans_with_malaria
Why does sickle cell anemia persist?
Primarily because of the same reason why any of us still persists, because even those people can reproduce. And it has been proven that people who has sickle cell anemia are immune to malaria.
The difference between sickle cell trait and sickle cell disease?
It has to do with your genitic make up. You don't have sickle cell anemia because you only have 1 of the traits on your beta hemoglobin gene. People with sickle cell anemia have two.Most of the time peolple with sickle cell trait display much milder symptoms. It is more prevolent in African Americans and woman should be monitored during pregnancy.
What does sickle-cell anemia do to the body?
Well reag anemia is where your red blod cells produced from bone marrow are very low in quantity. Your not having enough produced. Sickle cell is the same but the few being produced are shaped diff and in a way deformed and your RBC carry oxygen throughout body so with sickle cell the RBC u do have aren't healthy and can't appropriately deliver oxygen in reag anemia they can appropriately deliv oxygen but there are very few
Can a person have both sickle cell and hemophilia diseases at the same time?
Yes, Sickle cell affects the red blood cells while hemophilia is a condition where an extracellular protein is deficient in the person's blood.
Is there to many or too less chromosomes in sickle cell anemia?
Neither. People with sickle cell anemia have the same number of chromosomes and even the same number of genes as those who don't have the disease. The difference is a *change* in one of the genes. Actually, it is (usually) caused by a one letter difference in the hemoglobin gene which makes the hemoglobin produced more 'sticky' on a molecular level.
Is sickle cell anemia a disease from mutation?
Yes, but the mutation happened many many thousands of years ago. It has been passed on through all these generations because the same gene that causes sickle cell anemia in a person that inherits two copies of the gene also causes resistance to the malaria parasite in a person that inherits only one copy of the gene. In areas of the world where malaria is a common disease, the resistance to it is a stronger selective advantage than sickle cell anemia is a selective disadvantage; so the gene becomes very common in those populations.
The cause of sickle cell anemia is?
a child must inherit two copies of the defective gene in order to have a cystics fibrosis but when it come to sickle-cell anemia it is a disease passed down through families in which red blood cells from an abnormal sickle or crescent shape.Red blood cells carry oxygen to the body and are normally shaped like a disc so what causes sickle-cell anemia is the two copies that they get from both parents which gets passed down through families.
What people are most likely to develop sickle cell anemia?
there is no specific group of people can get this disease, but i can tell you that in some country you will find the majority of sick people accumulate in one region and that due to the marriage from the same place in this case the no. of sickle disease will increase in that particular area.
What is the medical term meaning erythrocyte with an irregular shape?
Sickle Cell Anemia is a genetic disease where the red blood cell (erythrocyte) takes on a sickle or crescent shape instead of the normal biconcave disk. Whereas the normal RBC is flexible and can easily travel through tight places in the joints, the sickle cell has no "give" and will bunch up in those same tight places causing inflammation, pain and heat.
Is hemoglobin s the same thing as hemoglobin solubility?
Hemoglobin S refers to the hemoglobin that forms in patients with sickle cell anemia. Hemoglobin solubility is a test that can be performed in order to determine if the patient has sickle cell anemia.
