Answer:
Changes in gene expression
Explanation:
This phenomenon is the result of changes in gene expression. That means, how the information in the DNA is used by the cell. The genes that are active in the cells of the brain will be very different from the genes that are active in the cells of the bone marrow.
These patterns of gene expression are different for each cell, and dictate the identity of that cell. Gene expression patterns are controlled by a variety of factors in the cell that allow tissue-specific expression, such a transcription factors.
This can also be facilitated by another layer of regulation called epigenetics, which literally means "on top of" genetics, and refers to modifications of DNA (and the proteins around it), that can reflect and influence the activity of the genes within.
Answer:
True
Explanation:
In central nervous system bundle if axons are called tracts or fasciculi. They are mostly named on the basis of their origin. Endoneurium layer which is very delicate surrounds axon. Impulses are carried toward the s brain through spinal cord ascending tracts while descending tracts carry impulses from higher regions of spinal cord or brain to the lower regions.
A.some of the genetic material is altered
Answer:
Explanation:
In Morgan reciprocal crossing
The result of crossing homozygous red-eyed female with a white-eyed male produced offspring with red eyes.
When homozygous white-eyed female was crossed with a red-eyed male, it produced red eyes females
and white eyes males.
