Answer:
The correct answer is A. ribosomes
Explanation:
Eukaryotic cell contains both membranous and non-membranous organelles. The membranous organelles are the nucleus, endoplasmic reticulum, Golgi apparatus, chloroplast(plants), mitochondria, lysosomes, etc.
Ribosomes, centrosomes are the non-membranous structures. Ribosomes are found in both eukaryotic and prokaryotic cells. In prokaryotes 70s ribosomes are present and in eukaryotes 80s ribosomes are present. Prokaryotes do not have a membrane-bound nucleus and organelles.
Ribosomes helps in protein synthesis in both prokaryotes and eukaryotes. Therefore the right answer is the ribosome.

Darwin’s ideas operate on the basis that organisms must change to survive in their environment. One of the key aspects of these changes is that they help the organisms utilize resources as effectively as possible. If there were unlimited resources there would not be a need for change. Malthus’s studies in limited resources shows how human populations changed to best use the resources available.
Bacteriophages like other viruses, consist primarily of a protein coat and ackaged DNA. Description on the function of critical enzyme; DNA helicase unwinds its two strands and makes a replication fork. The enzyme primase puts down a short RNA strand complementary to a short sequence of DNA being replicated to initiate a new strand of DNA. DNA polymerase elongates the new strand of DNA, building a new anti-parallel strand.
