Answer: The excretory system.
Explanation: The excretory system's function is to filter out cellular wastes, toxins and excess water or nutrients from the circulatory system.
Adenosine triphosphate (ATP) consists of an adenosine molecule bonded to three phophate<span> groups in a row. In a process called cellular respiration, chemical energy in food is converted into chemical energy that the cell can use, and stores it in molecules of ATP.

Answer:
DNA to messenger RNA (mRNA) to protein.
Explanation:
Central Dogma is a term that refers to the two step process through which information flows from the sequence of DNA into a sequence of RNA (the process of transcription) and finally takes the form of proteins (the process of translation)
Francis Crick was the first scientist who proposed the term of "Central Dogma".
Significance of Central Dogma:
- This is the process that ensures that genetic information of all living organisms is preserved and transmitted without any alteration or changes into their offspring.
- It is a process that intricately explains the logical mechanism through which DNA stored in our chromosomes express themselves into functional forms called proteins.
- This was the process which let us know the important roles of molecules like ribosomal RNA, transfer RNA and messenger RNA in the process of protein formation.
- The process has immense importance in understanding the latest advances in RNA technology that can further help in investigation and diagnosis as well as treatment of many critical diseases.

Cell divison is necessary to replace cells that are worn and aging. Cells do not have an indefinite life span. Fo example, the life span of a red blood cell is about 120 days.
