What are the genotypic differences between F-, F+ and Hfr cells?

Biology
1 answer:
Kitty [74]4 years ago
5 0

Answer:

The fertility factor or the F factor signifies a plasmid in some bacteria, which allows the conduction of genetic substance from a donor cell to the recipient by the process of conjugation, leading to recombination.  

The genotypic difference between the F- cells, F+ cells, and the Hfr cells are that the F- cells are devoid of the F factor, the F+ cells possess autonomous F factor, that is, a segment of DNA, which can replicate autonomously in the cell. In case of Hfr, the F factor is integrated into its chromosomal DNA, thus, they carry an integrated F factor.

The ____________ in the alveoli is 40 mm Hg and that of the blood entering the pulmonary capillaries is ____________ . This caus
Oxana [17]

Answer:

The <u>PCO₂</u> -carbon dioxide partial pressure- in the alveoli is 40 mm Hg and that of the blood entering the pulmonary capillaries is <u>45 mmHg</u>. This causes <u>carbon dioxide</u> to diffuse down its partial pressure gradient from the blood into the alveoli.

Explanation:

Gas exchange is a physiological process that involves the entry of oxygen into the body and tissues and the exit of carbon dioxide, a product of metabolic reactions.

At the pulmonary level, gas exchange occurs between the alveoli and the alveolar capillary, and the diffusion of gases across the alveolar-capillary barrier is dependent on a pressure gradient due to the partial pressure of gases.

In the case of CO₂ the diffusion goes from where the partial pressure is higher to where it is lower, i.e. <u>from the alveolar capillary, where the PCO₂ is 45 mmHg, to the pulmonary alveolus, where the PCO₂ is 40 mmHg</u>.

Lelu [443]

Answer:

The provided question is incomplete as there is no option available however the generalized answer would be -

The correct answer would be - For treating the global symptoms related to the allergies, it is known as that the inhaled nasal steroids are far more effective than oral medications.

Explanation:

Nasal steroids are the steroids that relieve congestion problems by decreasing the inflammation in the nose of an individual. These are then inhaled by the nose which directly sprays into nasal passages.

In comparatively the oral steroids take time to show their impact on the individual and even the impact is considered not as effective as the inhaled nasal sprays.

Thus, the correct answer is - For treating the global symptoms related to the allergies, it is known that inhaled nasal steroids are far more effective than oral medications.
