Question

lo 1.4. a ____ is composed of two subunits: the small ribosomal subunits (mrna), and the large ribosomal subunits, which form polypeptide chains of amino acids.
ribosome
lysosome
cytoskeleton
cytoplasm
nucleotide
chromosome
nucleus
mitochondria
vacuole

Explanation:

Ribosomes are cell - organelles made of two subunits. The small subunit reads mRNA, and the large subunit links amino acids to form polypeptide chains. Lysosomes are for digestion, cytoskeleton provides structural support, cytoplasm is the cell's internal environment, nucleotides are building blocks of nucleic acids, chromosomes carry genetic information, nucleus is the control center, mitochondria are for energy production, and vacuoles are for storage.

Answer:

ribosome
