Why do red blood cells not have a nucleus

Health
2 answers:
evablogger [386]3 years ago

Because of the lack of nuclei and organelles, mature red blood cells do not contain DNA and cannot synthesize any RNA, and consequently cannot divide and have limited repair capabilities.

The inability to carry out protein synthesis means that no virus can evolve to target mammalian red blood cells.

It simply allows the red blood cell to have more hemoglobin. The more hemoglobin you have, the more oxygen molecules you can carry. Therefore, it allows RBC to transfer more oxygen.

Lack of nucleus in RBC also allows the cell to have an unique bi concave shape that helps with diffusion

Answer:It allows the red blood cell to contain more haemoglobin and, therefore, carry more oxygen molecules. It also allows the cell to have its distinctive bi-concave shape which aids diffusion. This shape would not be possible if the cell had a nucleus in the way.

When inspecting the inside of the nares, what anatomical structure would not be visible?
faltersainse [42]

Answer:

Superior Turbinates

Explanation:

Turbinates are projections of the nasal wall of  the nasal cavity covered in mucus. They are the inferior, superior and the middle  based on their location in the nasal cavity. the superior is located between the inferior and the middle turbinates

The superior is not accessible during examination, but other two are visible. The help in the drainage of paranasal sinus and interpretation of smell because of the presence of nerve endings for smell in them

Turbinates  majorly the middle and the inferior increase the surface area for warming so that incoming air is raised to body temperature, they moistened  and filtered the inhaled  dust particles to prevent and dissolve the oxygen .

Most inflammation of the turbinates are from the middle and the inferior turbinates because they are the surface for passage of inhaled air.

describe the human body response at the cell level to perceived starvation threats as when a person is dieting or ill, tell why
Anon25 [30]
Briefly, the human body response to starvation at a cellular level results in a reduced metabolic rate and a switching of 'food supply' for various cells. Glucose is a primary cellular food source used by all cells in the body. During starvation with no additional glucose available to the body, glycogen stores (glucose stores) are consumed and then the body turns to consuming fat stores and muscle tissue (protein) to fuel it's cells. This means fat and muscle tissue is broken down during starvation periods. In the past during long periods of starvation, the ability for the body to survive without food input for weeks was necessary for survival. Today, whilst starvation no doubt yields weight loss results, it comes at a price. During starvation muscle tissue is invariably lost as the body needs glucose to power the heart and brain cells, which rely almost exclusively on glucose (which cannot be liberated from the break down of fats). As the body loses muscle tissue, it also loses the ability to burn as much energy because muscles are a key energy user. The body also loses strength in general. It therefore is a hindrance to starve for modern weight loss objectives and a better option is high level of exercise with reduced calorific food intake. This will maintain muscle tissue and favour fat loss.
