What is the function of ribosomes?

The function of ribosomes is to synthesize or to make proteins.

Explanation:

A ribosome is an organelle that is present within the living cells.

ribosomes are made of protein and ribonucleic acid(nucleic acids.) that serve as the site for the production of protein in the cell.

A protein produced by the ribosome is required by the cell to repair damage and for the chemical process. Thus protein synthesis is highly essential to cells.

answer: c

explanation:

before, trains worked using the steam engine. thus, it uses heat so it is crucial to apply heat balance. the steam engine absorbs energy during the stage of boiling water. so, this is the endothermic reaction. when the steam is used to work the piston, it has to release this energy through running the train. the excess energy is released as an exhaust to the chimney. this is the exothermic process because it releases energy to the surroundings.
