Answer:
Water
Oxygen
Carbon dioxide
Lipids
Explanation:
The plasma membrane is a lipid bilayer with a hydrophobic core made of nonpolar tails of phospholipids. The plasma membrane allows only uncharged, small and hydrophobic substances to pass through it. Charged particles such as ions, polar molecules such as sucrose can not cross the hydrophobic core of the plasma membrane.
Oxygen and carbon dioxide gases have small sizes and can diffuse through the spaces between the tails of phospholipids of lipid bilayer of the plasma membrane without any transport proteins. Lipids are hydrophobic and therefore, do not need any transport proteins to cross the lipid bilayer. The small water molecules are also free to move through the membrane.
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.
