The biological molecules that transport other substances are the proteins.

<h3>What are proteins?</h3>

Proteins are biological macromolecules that contains nitrogen in their molecules and are the building block of a living organism.

The proteins perform the following functions:

What is the density of chlorine gas (MM = 71.0glmol) at 1.50 atm and 25.0C
IrinaVladis [17]

Answer: D=4.35g/L

Explanation:

The formula for density is D=\frac{M}{V}. M is mass in grams and V is volume in liters.

Since we are give pressure and temperature, we can use the ideal gas law to find moles/volume. FInding moles/volume would give us the base for density. All we would have to do is convert moles to grams.

Ideal Gas Law: PV=nRT

\frac{n}{V} =\frac{P}{RT}

\frac{n}{V}=\frac{1.50 atm}{(0.08206Latm/Kmol)(25+274.15K)}

\frac{n}{V} =\frac{0.061309mol}{L}

Now that we have moles, we can use molar mass of chlorine gas to find grams.

0.061309mol*\frac{71.0g}{mol} =4.3529g

With our grams, we can find our density.

D=\frac{4.3529g}{L}

We need correct significant figures so our density is:

D=\frac{4.35g}{L}

How does fermentation that causes dough to rise differ from fermentation in muscles?
mote1985 [20]
Fermentation that causes dough to rise is alcoholic acid, and this is when the alcohol is rising and leaving the dough. In a human, we don't have alcohol, or else we would be drunk after we work out. Instead, we have Lactic Acid fermentation, and this is when you use up too much oxygen, so fermentation make us really tired or else, we wouldn't be able to keep working out.
