Answer:
The best answer from the choices, to the question: The cause of the hyperventilation is described by which of the following statement:___, would be, B: A decrease in the bicarbonate concentration stimulates ventilation.
Explanation:
The acid-base balance in the human body, is a very restrictive one. Normal ranges in this base are: 7.35 to 7.45. Whenever the values go either below 7.35 or above 7.45, we are talking about a person going into acidosis or alkalosis. Both situations are pretty serious and they have to do with the balance between the amounts of bicarbonate, and CO2 in the form of carbonic acid, in the blood. The normal ratio of bicarbonate to carbonic acid, is usually 20:1. Chemoreceptors, especially central ones in the neck, measure constantly that the balance is kept and if this is not the case, then several mechanisms will be put into place to recover it. One such measure is respiratory, and the other is metabolic. In the case of this 17-year-old, he has a pneumonia, which means that from the start, one of his recovery mechanisms is impeded, which is the respiratory mechanism of balance. He is also having metabolic problems with his system of compensation because his body is already producing high levels of H+ ions and not enough bicarbonate. Hyperventilation in this person is attempting to expel as much CO2 as possible, to try and restore the balance. The first thing that is sensed by the receptors is the changing in the 20:1 ratio, the increase in pH due to too much carbonic acid, and thus the body initiates the use of CO2 expulsion by the lungs, while metabolic mechanisms come into play.
Answer:electron,atoms,molecules
Explanation:
The nurse's best course of action for an 11-year-old youngster with many tenders & swollen lymph nodes is to let the child participate in the conversations.
Including the youngster in the conversation would help to relax and divert attention from Tender, uncomfortable nodes that develop and spread within a short period, usually as a result of an inflammatory condition in the region where the lymph nodes drain. The presence of lymphoma or leukemia is occasionally seen in a patient having tender, quickly expanding lymphadenopathy.
One of the most frequent causes of enlarged lymph nodes, including those that may be felt in the neck, is upper respiratory infections.

Answer:
- Constituyen un alimento mas rico en vitaminas y minerales.
- Cosechas que soportan sequias y condiciones extremas.
- Menor costo de produccion.
- Caracteristicas deseables en las plantas.
- Menor uso de pesticidas.
Explanation:
Los transgenicos, o GMO, son alimentos geneticamente modificados con la finalidad de crear un producto de mayor calidad utilizando genes de otro organismo.
Los alimentos transgenicos suelen ser criticados constantemente por la poblacion ya que muchas personas creen que son dañinos para la salud. Sin embargo, estudios cientificos señalan que son sumamente beneficos en diferentes maneras. Por ejemplo:
- Constituyen un alimento mas rico en vitaminas y minerales que beneficia significativamente a poblaciones que se encuentran en pobreza.
- Cosechas que soportan sequias y condiciones extremas que una planta no transgenica no podria soportar.
- Menor costo de produccion.
- Caracteristicas deseables en las plantas. Por ejemplo, mayor tamaño o fruta mas jugosa.
- Menor uso de pesticidas. Hoy en dia, se sabe que el sobreuso de pesticidas ha ocasionado consecuencias irreparables en el medio ambiente y en la salud humana.
