Explain why red blood cells are unable to replace damaged proteins

Harman [31]

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.

According to friedrich, when food and fluid intake is poor, starvation occurs before dehydration

Solnce55 [7]

The statement of Liz Friedrich is verified by evidence from research of a physiologic adaptation, during the vanishing development, the famine that averts any uneasiness as a outcome of the absence of food. Dehydration may result to hemoconcentration and hyperosmolality, with consequent azotemia, hypernatremia, and hypercalcemia. These metabolic fluctuations may create a soothing effect on the brain before passing away.

Describe the five categories of the vertebral column.

gladu [14]

Answer:

The five categories of vertebral column are:

Cervical
Thoracic
Lumbar
sacrum
coccyx.

Explanation:

The 26 vertebrae of the spine or vertebral column are classified into five categories based on the structural differences between them. The first category is cervical and is made of seven cervical vertebrae. The spines of cervical vertebrae are shorter than that of others and have bifurcations.

The next category is the thoracic and is made of twelve thoracic vertebrae. Thoracic vertebrae are followed by lumbar region made up of 5 lumbar vertebrae. Spines of thoracic vertebrae are longer and are directed downwards while that of the lumbar vertebrae project towards the posterior region. the sacrum is present below the lumbar region and consists of five fused sacral vertebrae. The last category of spine is coccyx. It has four fused coccygeal vertebrae.
