If a woman with vaginal bleeding reports syncope, the EMT should assume that she "is in shock".
<u>Option: B</u>
<u>Explanation:</u>
The most common form of syncope is the Vasovagal syncope. It is triggered by a dramatic drop in blood pressure, resulting in a decline in blood flow to the brain. When one stand up, gravity causes blood to settle down below one's diaphragm, in the bottom part of their body.
It is a component of a wider class of medical conditions which may lead in TLOC involving postural orthostatic tachycardia syndrome (POTS), orthostatic hypotension and neurologically mediated syncope (NMS). The overlapping of such clinical symptoms causes confusion about the category of syncopes which may complicate assessment approaches and present difficulties for diagnosis and treatment, especially in young women.
I think the correct answer from the choices listed above is option C. The function that is both performed by goblet cells and lacrimal glands is protection. They produce mucus in order to protect mucous membranes. Hope this answers the question.

The right answer is polarity.
In chemistry, polarity is a characteristic describing the distribution of negative and positive charges in a dipole. The polarity of a bond or a molecule is due to the difference in electronegativity between the chemical elements that compose it, the differences in charge that it induces, and to their distribution in space. The more the charges are distributed asymmetrically, the more a bond or molecule will be polar, and conversely, if the charges are distributed in a completely symmetrical manner, it will be apolar, that is to say non-polar.
Polarity and its consequences (van der Waals forces, hydrogen bonding) affect a number of physical characteristics (surface tension, melting point, boiling point, solubility) or chemical (reactivity).
Many very common molecules are polar, such as sucrose, a common form of sugar. The sugars, in general, have many oxygen-hydrogen bonds (hydroxyl group -OH) and are generally very polar. Water is another example of a polar molecule, which allows polar molecules to be generally soluble in water. Two polar substances are very soluble between them as well as between two apolar molecules thanks to Van der Waals interactions.
