<span>The hormone INSULIN is released from the pancreas when blood glucose is elevated above a normal range.
This hormone regulates your blood sugar level. When your blood glucose is elevated above a normal range, the insulin is released from the pancreas. It then attaches itself to the cells and signals them to absorb the excess sugar from the blood stream.
If your blood sugar level is low, insulin signals the release of stored sugar to the blood stream to maintain the normal level of your blood glucose.</span>
Movements of tectonic plates create volcanoes along the plate boundaries, which erupt and form mountains. A volcanic arc system is a series of volcanoes that form near a subduction zone where the crust of a sinking oceanic plate melts.
No, the sickle-cell anemia allele won't be eliminated by natural selection.
Sickle-cell anemia trait is controlled by a single gene and the allele (S) for sickle-cell anemia is a harmful autosomal recessive.
It is caused by a mutation in the normal allele (A) for hemoglobin (a protein on red blood cells).
Heterozygotes (AS) with the sickle-cell allele are resistant to malaria, a deadly tropical disease. It is common in many African populations.
In these areas, (S) carriers have been naturally selected, because their red blood cells, containing some abnormal hemoglobin, tend to be in sickle shape when they are infected by the malarial parasite.
Therefore, they are more likely to survive and reproduce. This keeps the S allele in the gene pool.
