What is the molecule rrna a component of?
a. vacuoles
b. centrioles
c. ribosomes
d. microtubules

c. ribosomes

Explanation:

Like DNA, RNA (ribonucleic acid) is a nucleic acid. This molecule is essential in the synthesis of proteins, since it functions as an intermediary capable of expressing the information present in the DNA. The RNA molecule is formed from the DNA molecule in a process called transcription.

There are three types of RNA, which are tRNA, rRNA and mRNA.

Ribosomal RNA (rRNA) is one of the structural components of the ribosome. It is the rRNA that coordinates the interaction between mRNA, tRNA and proteins, during the process of protein synthesis.

4.) metal

"-the movement of carbon from the nonliving environment into living things and back to the environment

-carbon is the essential component of proteins, fats, and carbohydrates (which make up all organisms)

-carbon exists in air, water, and living organisms

-producers convert carbon dioxide in the atmosphere into carbohydrates during photosynthesis

-bacteria in the atmosphere cycles through the system in filtration units

-in cellular respiration, carbon is released back into the atmosphere as carbon dioxide

-some carbon is stored in limestone (forming one of the largest "carbon sinks" on earth)

-largest carbon reservoir on earth= limestone

-carbon stored in the bodies of organisms as fat, oils, or other molecules may be released into the soil or air when the organism dies

-this may form deposits of coal, oil, or natural gas (fossil fuels, which increased the atmospheric carbon dioxide)

-fossil fuels store carbon left over from bodies of organisms that died millions of years ago

-they are located in the surface of earth, deep within the earth and beneath the ocean floor."
