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.
Melting of ice and island decreasing in level
The answer is C) Cloning eliminates the ability to sexually reproduce and provide genetic variability.
In the future, there is no variability in the genes in the clones given that they are the exact copies of the "parent" produce. All should be identical without differences and variations. Although Farmer Brown doesn't want this to happen that's is what he is reluctant to listen to Farmer Green's advice.
Answer:
The semicircular canals ( vestibular system)
Explanation:
The inner ear of humans is made up of two parts.
- The cochlea which aid in the hearing process.
- The vestibular system which aid for balance of the body
The vestibular system comprises of three fluid filled looped canals . The vestibular system comprises of sensory cells which detect even a slight tilting of the head. The fluid filled canals are termed as the semicircular canals. It is due to the vestibular system that we feel a room to bespinning even after we have finished our rotation ride.
Answer:
It combines genes from two different organisms.
