An illegal drug stimulates the parasympathetic nervous system, causing the user to appear tranquilized. What could indicate to a paramedic whether or not the person took this drug?A. High blood pressure and drooling
B. Low blood pressure and drooling
C. High blood pressure and dry mouth
D. Low blood pressure and dry mouth

Answers

Answer 1

Answer: B. Low blood pressure and drooling. If the user is tranquilized, he would not be able to hinder the production of saliva, leading to drooling. And if the victim was tranquilized, his heart would slow down, not speed up, resulting in a lower blood pressure.

The combustion of 14 grams of co according to the reaction co(g) ½o2(g) co2(g) 67.6 kcal gives off how much heat?

Answers

The balanced reactionthat describes the reaction between carbon monoxide and oxygen to producecarbon dioxide is expressed co(g)+ ½o2(g) → co2(g). The heat of combustion is 67.6 kcal per mole CO. We are given with 14 grams CO. Convert this to mole equal to 0.5 mole. Hence the total heat is 33.8 kcal.

Answer:

It is 33.8.

The correct answer to complete the sentence is C. The combination of two or more atoms, from the same or different elements, creates a molecule. Compounds are a type of molecules made of atoms from different elements held together by chemical bonds.

Which part of the body contains enzymes that break down protein? A. Skin B. Brain C. Stomach D. Teeth

Answers

Enzymes for the breakdown of protein are present in the stomach.

What are the enzymes involved in the digestion of proteins in our body?

Pepsin

In the presence of an acid, the stomach secretes pepsins, which are proteolytic enzymes.
About 10–15% of the digestion of proteins is done by the pepsins.

Trypsin

It is secreted in an inactive form, trypsinogen, by the pancreas.
Trypsinogen is then activated in the small intestine by the enzyme enterokinase and further helps in protein digestion.

Chymotrypsin and elastase

These are also secreted by the pancreas.
Chymotrypsin and elastase are activated by trypsin.
Responsible for initiating the hydrolysis of protein chains into peptides.

Carboxypeptidases

The enzymatic action of carboxypeptidases, which are also released by the pancreas, causes the subsequent breakdown of the peptides into smaller molecules and then to individual amino acids.

Given the balanced equation representing a reaction:NH3(g) + H2O(l) ==>NH4+(aq) + OH-(aq)
According to one acid-base theory, the NH3(g) molecules act as
(1) an acid because they accept H+ ions
(2) an acid because they donate H+ ions
(3) a base because they accept H+ ions
(4) a base because they donate H+ ions

According to the Bronsted-Lowry concept of acids and bases, a base accepts protons. Here NH₃ accepts a proton to form the conjugate acid NH₄⁺. Hence, it acts as a base.

What is Bronsted-Lowry concept?

There are various theories regarding the nature of acids and bases. According Bronsted-Lowry concept of acids and bases, acids are substances which donates a proton and bases are proton accepters.

The species which is formed by donating a proton from the acid is called conjugate base of the acid and the species which is formed after a base accepts a proton is called the conjugate acid of the base.

Consider the given reaction of ammonia with water. Here water is a proton donor and thus acts as an acid whereas ammonia accepts the proton from water forming its conjugate acid NH₄⁺. Water forms its conjugate base OH-. Therefore NH₃ acts as a base in this reaction.
