At sites of seafloor spreading along divergent plate boundaries, this crust is separated into parallel bands of rock by successive waves of emergent magma. When Earth's geomagnetic field undergoes a reversal, the change in polarity is recorded in the magma.

Classification system originated in the 18th century, from the works of a Swedish botanist Carolus Linnaeus. He classified living beings based on similarities between them. Organisms which could interbreed were put in one species.
The correct answer is "the formation of new brain cell connections as the result of reading a book".
Usually, neuroplasticity is apparent in young children when the central nervous system has an abundance of neurons. This is always in the context of forming new brain cell connections or synapses that will lead the person to access the information quicker. This also exemplifies the principle of use and disuse when it comes to knowledge.
The other choices concerns the skeletal system, cardiovascular system, and the endocrine/reproductive system; all of which do not have a relation with neuroplasticity.
Answer:
1. What genes control the growth of cell growth?
2. What is the purpose of this regulation?
3. What happened when the cell growth is not regulated?
Explanation:
What genes control the growth of cell growth? What is the purpose of this regulation? What happened when the cell growth is not regulated?
Above are the questions which an observe would ask about regulation of cell growth. A number of genes such as oncogenes and tumor suppressor genes are involved in the regulation of cell growth and cell division. Regulation of cell growth process ensures that a cell's DNA which is dividing is copied properly as well as repair errors in the DNA. It also ensures that each daughter cell receives a complete set of chromosomes in order to gain healthy daughter cells.
