The correct answer is "securing the airway and providing ventilation".
It has been proven that the first priority when dealing with drowning victims is to try and resuscitate the victim. This is done by securing the airway and providing ventilation. Especially, in this prehospital stage, the first responders should assess the airway, breathing, circulation and cervical spine. After securing that the victim has normal breathing and circulation, the healthcare professional should focus on correcting any abnormal physiological functions, such as hypoxia and hypothermia.

Effectus [21]

Answer:

The correct answers are:

1. closing

2. the ventricles and arteries,

3. a constricted trachea

Lub is the first sound of a heartbeat and is mentioned as S1. It is usually produced due to the closing of tricuspid and and mitral or bicuspid valves present between atria and ventricles.

Tricupsid is located between atrium and ventricle of the right hand side and mitral valve is located between atrium and ventricle of the left hand side. They prevent the back flow of blood from ventricles to their respective atria.

Dub, being the second sound is written as S2. It is produced due to the closing of pulmonary (located between right ventricle and pulmonary artery) and aortic valves (located between left artery and aorta).

These valves prevent the back flow of blood from arteries into the ventricles.

The time between the two sounds is often taken as the measure of the diastole i.e. ventricular filling.

Wheezing refers to a high-pitched sound produced when a person breathes, especially during exhale. It is caused by constriction of the airways or inflammation. It is considered as a symptom of various diseases such as asthma, COPD, allergies, bronchitis etc.

Why can't prokaryotic species be defined as a group of similar organisms that could sexually reproduce together?
s344n2d4d5 [400]

Answer:

The prokaryote divides by asexual mode of reproduction.

Explanation:

The concept of species which defines a species as a group of individuals of a population which can interbred and produce a fertile progeny is applicable to the organism which can reproduce sexually.

Since the bacteria divide through asexual means and not through sexual ways therefore the concept of defining a species becomes complicated and does not apply.However the concept of species in prokaryotes is still a topic of research.  

Thus, the biological concept of species is not applicable to prokaryotes.
