julsineya [31]

Answer: Natural selection.

Explanation:

The concept of natural selection was given by Charles Darwin.
According to this concept, in a given environment the organisms that possess better adaptations have higher chances of survival and, leave behind a greater number of progenies.
When malaria outbreak occurs, the allele frequencies change and only the organisms that possess the alleles which help them to survive this outbreak due to resistance against malarial infection will be selected by nature and hence, this is an example of natural selection.

Unattached microbes are moved from the lungs to the epiglottis by the _______ effect.

lisov135 [29]

Answer:

The unattached microbes are moved from lungs to epiglottis by the mucociliary escalator effect.

Explanation:

Mucociliary escalator, also known as mucociliary clearance, is one of the major defense mechanisms that protects the lungs. It describes the self-cleaning mechanism of the bronchi which are present in the lungs. The effectiveness of this mechanism depends on the properties of the produced mucus and on the quality and number of the cilia present in the lining of the airway.

Therefore, the unattached microbes are moved from lungs to epiglottis by the mucociliary escalator effect.

The registered nurse is overseeing a nursing student who is providing a dressing change to a patient who had a cesarean section.

natulia [17]

The nurse conducting wound care should choose a dressing that keeps the periwound skin dry and the surgical wound bed moist to contribute healing. The dressing used for wound care should control exudate from the wound, but it should not desiccate the wound bed. There must be a pressure in application while cleaning the periwound and wound may deepend the wound bed. Using sterile normal saline and a sterile gauze to clean the surgical wound reduces the incidences of infection.
