ANSWER:
Brain cells that are neither neurons nor glia, but which are capable of dividing and then differentiating into neurons or glia, are called NEURAL STEM CELLS.
EXPLANATION:
Neural stem cells are undifferentiated cells originating in the central nervous system.
Neural stem cells (NSCs) have the potential to give rise to the radial glial progenitor cells that grow and differentiate into neurons and glial cells.
NSCs have an important role during development producing the enormous diversity of neurons, astrocytes and oligodendrocytes in the developing CNS.
A NEURON (nerve cell) is a specialized cell that conveys electrochemical impulses throughout the body.
provide support for and insulation between them.
GLIAL CELLS are the most abundant cell types in the central nervous system. Types of glial cells include oligodendrocytes, astrocytes, ependymal cells, Schwann cells, microglia, and satellite cells.
It is known as a innate behavior
Answer:
A person with sickle cell trait has one mutated copy of the hemoglobin gene, a person with sickle cell disease has two mutated copies.
Explanation:
Sickle cell disease also known as sickle cell anemia is caused by mutation of the beta chain of hemoglobin, the gene for which lies in 11th number chromosome. If a person possess only one mutated gene, then the disease is not expressed in the person. The person then only possess the trait for sickle cell anemia, that is, there is a chance of sickle cell disease in the offspring, but the sickle cell trait are usually asymptomatic or live like normal individual. While the person possessing two mutated gene is said to be suffering from sickle cell anemia and is found to possess S hemoglobin in the red blood cells which is abnormal hemoglobin without any ability to carry oxygen.
