Answer:
2. Such regions play a significant role in gene regulation. That is why they remain conservative under the influence of natural selection.
Explanation:
Within the genome there are many non-coding regions that control the expression of master developmental genes such as, for example, Hox major transcription factors (TFs) in animals and MADS-box TFs in plants. These gene regulatory regions (e.g., promoters and enhancers) are generally evolutionarily conserved within certain taxonomic groups. In consequence, such non-coding regions are well known to be conserved and interact in a sequence-specific manner with major transcription factors in order to regulate developmental pathways.
Answer: c. produce hormones that help regulate many body functions
Explanation:
The endocrine system helps in the release of hormones and regulating them into bloodstream and these hormones that are released then travel to the cells to perform different functions like growth and development, reproduction, controlling of ones mood, metabolism etc.
Therefore, the correct option is C "produce hormones that help regulate many body functions"

Answer:
Explanation:
Los cambios físicos ocurren cuando los objetos o sustancias experimentan un cambio que no modifica su composición química. ... En general un cambio físico, o un método físico, puede modificar la composición de una mezcla. Por ejemplo, la sal disuelta en agua puede ser recuperada dejando evaporarse el agua.
