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.

Crop rotation does all the things listed in the options exceptoption d. organic fertilizer.
Crop rotation is a farming practice that involves the systematic planting of different crops in a specific order over time. It offers several benefits to agricultural systems, including minimizing erosion, letting fields lie fallow (rest) to restore soil health, and returning nutrients to the soil. However, crop rotation itself does not involve the use of organic fertilizer. Instead, it focuses on the strategic arrangement of crops to enhance soil fertility and reduce pest and disease buildup.
Therefore, the correct answer is d) organic fertilizer.

The answer is Gravity. To ensure the one-way flow of blood the veins contain a network of valves which arteries do not have. The reason is for the veins to counteract the force of gravity on flow of blood. For example, to increase the pressure of the blood back to the heart the veins must counteract the force of the gravity.
Answer: A) gravity
Explanation: I Took The Pre-Test On US Test Prep.
Mitosis is a type of cell division where one parent cell divides to produce two genetically identical daughter cells. In diploid organisms, mitosis produces diploid daughter cells.
In conclusion, if a cell with six chromosomes undergoes mitosis, it will produce TWO daughter cells that contain SIX chromosomes.

Answer:
hii dear your answer is here
2 daughter cells with 6 chromosomes each.
Explanation:
If a cell with six chromosomes undergoes mitosis, it will produce 2 (number) daughter cells that contain 6(number) chromosomes.
Answer: prokaryotic flagella use a rotary motor, while eukaryotic flagella use a complex sliding filament system.
Eukaryotic flagella are ATP-driven, while prokaryotic flagella can be ATP-driven (Archaea) or proton-driven (Bacteria).
