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:
The study of fish is called Ichthyology.
Explanation:
Fish specimens are identified in the field by ichthyologists. Ichthyology is the field of study that deals with fishes. Taxonomy (classification and the description of new species) and biogeography are the two main areas of focus for museum ichthyologists (patterns of distribution).
Ichthyology is the field of study that deals with fishes. Taxonomy (classification and the description of new species) and biogeography are the two main areas of focus for museum ichthyologists (patterns of distribution). Large reference collections of preserved specimens are kept in museums as a permanent resource for present-day researchers as well as for future ones.

Answer:
This statement is true
Explanation:
The genetic code is required for the production of proteins with exception of some few mitochondrial proteins. The transfer RNA (tRNA) acts as an adaptor that enables to associate a messenger RNA trinucleotide sequence (known as anticodon) with its corresponding amino acid in the polypeptididic chain. The genetic code is considered to be a biochemical system capable of revealing the information contained in the DNA in order to synthetize a protein, which has been encrypted in the form of three nucleotides (i.e., codons).
