i think science is an interesting and essential subject, mainly i like the fact that having knowlege of biology,etc can help patients and sick people. Its obvious science is an important subject. But science cant explain everything, like about religion for instance scientists say the universe is created from big bang but religious people say god made it , so yeah. I mostly love science because of how amazing doctors are, helping people and all.
what do you think about science from your own experiences we cant answer this for you

D) 48
Answer:
A
Explanation:
The sole reason why red blood cells are unable to replace damaged proteins is that red blood cells lack DNA and cell organelles such as nucleus, ribosomes and mitochondria which are crucial for protein synthesis, assembly and repair. In other words they lack both the information and the machinery for making or repair of proteins.
Due to lack of DNA and cell organelles, red blood cells cannot be able satisfy the central dogma which summarizes synthesis of proteins as DNA → RNA → proteins.
DNA has the genetic information on how proteins should be made, RNA is responsible for transferring the information from DNA in the cell nucleus to the ribosomes in the cytoplasm, then translating or decoding this information, which results in the making of protein.
Red blood cells (RBCs) are unable to replace damaged proteins because they lack a nucleus and organelles, including mitochondria. Instead, new RBCs are constantly produced in the bone marrow to replace damaged or aged ones. When RBCs are damaged or aged, macrophages phagocytize them.
Red blood cells (RBCs) are unable to replace damaged proteins because they lack a nucleus and organelles, including mitochondria. This means that RBCs cannot synthesize new proteins to replace damaged ones. Instead, RBCs have a limited lifespan and are constantly being replaced by new RBCs produced in the bone marrow. When RBCs are damaged or aged, they are phagocytized by macrophages in the spleen, liver, and bone marrow.
