Answer:

Uvula

Explanation:

The uvula is a fleshy structure found at the back of the soft palate in the mouth. It is the structure seen hanging at the back of the throat when someone opens his/her mouth and views in the mirror.

<em>The uvula is made up of flexible tissues with the ability to produce saliva. During eating or swallowing of food, the uvula along with the soft palate move to seal off the pharynx in order to prevent food materials from entering the nasal passage.</em>

Answer:

Uvula

Explanation:

The uvula is that soft fleshy tissue structure that looks like the shape of a teardrop that is found at the back of your throat. It is this structure that helps in preventing food from entering the pharynx or nasal passage.

The uvula, which is made of connective tissue, saliva-producing glands and few muscle tissues, is the main structure that is responsible for all throat functions, including stopping food from entering the nasal passage by blocking the nasal passage and directing the food down your esophagus as food is swallowed.

Aside this function, the uvula also helps in fighting infections by preventing pathogens that causes disease from passing through the throat.

You hear someone mention the molecule "amp." based on what you learned about the structure of atp and the way in which energy is
polet [3.4K]

ATP stands for Adenosine Triphosphate. This sounds like a complicated name, but when we break the name down, it's really a simple description of what makes up the ATP molecule. (***see attached pic***)

I don't know how in depth you need to know the structure of ATP, so let's keep it simple.  There are two major parts of the molecule (one is called "adenosine" and one is the "3 phosphates").  If you know that the prefix "tri-" means "3", then you can see that the name ATP is simply just telling you about the make-up of the molecule.

AMP stands for adenosine MONOphosphate. Therefore, it's two major parts are adenosine and 1 phosphate (because "mono-" means "1").

The energy from ATP comes from the bonds between the phosphates. Think of the molecule like a battery. The more phosphate bonds, the higher charged it is. Therefore, ATP has much more energy to release and power cellular functions than AMP does. AMP is actually the bi-product of the cell breaking ATP's phosphate bonds to release energy from them and power cellular functions.
