Answer:
a. True
Explanation:
Ribosomes are ribonucleoprotein complexes composed of RNA and proteins, which have two main roles 1-decode the message of the messenger RNA (mRNA) molecule and the formation of peptide bonds in the protein. For this purpose, each triplet of nucleotide bases or 'codon' in the mRNA sequence is used to assemble specific amino acids in the nascent polypeptide chain. Although different, both prokaryotic ribosomes and eukaryotic ribosomes are composed of two subunits: one small subunit that decodes the mRNA into a specific amino acid chain, and one large subunit that forms the peptide bonds in the polypeptide chain. Each ribosomal subunit is in turn composed of ribosomal RNAs and proteins. These ribosomal RNAs act as scaffolds by combining with proteins that assemble into ribosomes (i.e., small and large ribosome subunits).
The Nucleus is separated from the cell’s cytoplasm by a
membrane. The nucleus contains hereditary materials made of plenty proteins and
DNA. The nucleus directs all cell activities. Nucleus is commonly found in
Eukaryotic cells. The genetic materials found in the Nucleus is organized as
DNA molecules, together with a wide array of proteins, which causes to form
chromosomes.

Unequal reproductive success - Accumulation of favorable traits over time. Unequal reproductive success. heritable traits best suited to the local environment are more likely to survive and reproduce. Accumulation of favorable traits over time.
Explanation:
Where Translation Occurs. Within all cells, the translation machinery resides within a specialized organelle called the ribosome. In eukaryotes, mature mRNA molecules must leave the nucleus and travel to the cytoplasm, where the ribosomes are located.
