Answer:
Ultimately what makes each cell different despite the fact that they share the same set of DNA is regulation of gene expression, which regulates the expression of genes. In other words, it determines which genes are turned off and which are turned on in a cell. Gene expression can be regulated in many ways; it's mainly centered around molecules like transcription factors that have the ability to turn certain genes on and off and activators, which promote transcription of DNA.
The short answer to this question is cell differentiation. Differential gene expression results from the genes being regulated differently in each cell type, and differential gene expression leads to different cells.
In fact, from the very beginning of our lives, so to speak, when we're developing from a zygote into an embryo, the egg that makes up the zygote in fact already has a sequential program of gene regulation tat is carried out as cells divide, and this program makes the cell become different from each other in a coordinated fashion.
Answer:
As an injury of the central nervous system.
Explanation:
Peripheral nervous system is the nervous system outside the brain and spinal cord. The central nervous system consists of the brain and spinal cord. The autonomic nervous system is a control system that acts largely unconsciously and regulates bodily functions, such as the heart rate, digestion, respiratory rate, and more. The somatic nervous system is the part of the peripheral nervous system associated with the voluntary control of body movements via skeletal muscles. Therefore, central nervous system is your answer!

<span>To prove his Theory of Evolution. After studying the different species of finches he found the Galapagos Islands, Darwin focused on breeding pigeons by selecting specific traits of different individuals (this is mainly a method through which different kinds of dog breeds came about). On the basis of these studies Darwin concluded that natural selection and artificial selection acted roughly in the same way. Darwin's decision to enforce a certain trait represented, in a sense, the selective pressure which is present in a natural environment (the law of the fittest).<span>

Mitosis is important for sexual reproduction indirectly. It allows the sexually reproducing organism to grow and develop from a single cell into a sexually mature individual. This allows organisms to continue to reproduce through the generations.
