You will need to look up some conversions of gram to lbs

1 gram = 0.00220462262 pounds


1 mL = 0.000264172052 US gallons

and mL to gal

1.035 g / cm^3 x 0.0022 lbs / 1 gram x 1 mL / 0.000264 gal

Answer:

The average density of whole milk is 8.6291 lbs/gal.

Explanation:

The average density of whole milk is 1.034 g/cm ^3.

1 g = 0.00220462 lbs

1 cm^3=0.000264172 gallons

1.034 g/cm ^3=\frac{1.034\times 0.00220462 lbs}{1\times 0.000264172 gal}

=8.6291 lbs/gal

The average density of whole milk is 8.6291 lbs/gal.

En un recipiente colocamos unos cubos de hielo luego tapamos y observamos que sucede despues de un tiempo
SSSSS [86.1K]

Three questions come along with the given statement. It is in Spanish language:



a) Por qué se humedeció la parte exterior del frasco?


b) Por qué el hielo disminuyó su volumen y ahora es agua?


c) Por qué puede haber agua en el exterior?



These are the three answers (in English).



First question:



a) Por qué se humedeció la parte exterior del frasco?



The question is Why did the outside of the bottle get wet?



Answer:



The outside of the bottle get wet because the ice cubes cooled the walls of the bottle, so the air surrounding the bottle also cooled.



The air contains humidity (water) in gas phase. The hotter the air the more the amount of humidity it can retain, the cooler the air the less the amount of humidity it can retain.


Then, when the air close to the walls of the bootle got cooler some of the water in the air became liquid and those are the drops of water that you see in the outside of the bottle.



Second question



b) Por qué el hielo disminuyó su volumen y ahora es agua?



The question is Why did the ice diminish its volume and now it is water?



Answer:




The ice diminished its volume and now it is water, becasue the ice, which is cooler than the surroundings, received heat energy (from the surroundings) and then its temperature increased. At some moment, this temperature reached the melting point of the ice (water) and it started to become liquid.



Third question



c) Por qué puede haber agua en el exterior?



The question is: Why can there be water outside?




Answer:



The water outside is outside since the beginning: it is in the air. You do not see it because it is gas state. When the air close to the walss of the bottle got cooler, part of the water in the air became liquid.

Collagen is made of fibers and is found in tendons and cartilage. Collagen
BartSMP [9]

Answer:

Collagen is a "fibrous proteins" present in the extracellular matrix.

Explanation:

Protein are made up of hundreds or thousands of smaller units called amino acids and is made of carbon, hydrogen, oxygen, nitrogen and sometimes sulfur and is found in many foods. Proteins are organic molecules found in living organisms.

There are three types of proteins; fibrous, globular, and membrane.

Collagen which is a fibrous proteins, form muscle fiber, tendons, connective tissue and bone.

Collagen are naturally occurring proteins that consist of single molecules made up of amino-acids, which are in turn built of carbon, oxygen and hydrogen. It is mostly found in fibrous tissues such as tendons, ligaments, and skin.

The synthesis of collagen occurs in two stages: intracellular and extracellular.

Collagen is an abundant connective tissues such as cartilage, tendons, bones, and ligaments. Collagen is a contributing factor to variation in meat tenderness and texture.
