Protiens can help fight specific diseases, always there to regulate cell processes and build muscle/tissues.

Structural proteins also known as Fibrous proteins, are necessary components of your body. They include collagen, keratin and elastin. Collagen forms the connective framework of your muscles, bones, tendons, skin and cartilage. Keratin is the main structural component in hair, nails, teeth and skin.

• Nucleic acids store and transmit heredity.

A redox reaction is a type of reaction which involves transfer of electrons among two species. This reaction is also called oxidation-reduction reaction.

In oxidation process, there is an increase in oxidation state of an atom, ion or molecule by losing the electrons.

In reduction process, there is a decrease in oxidation state of an atom, ion or molecule by accepting the electrons.

1)

In this reaction, Ba undergoes oxidation and Cl undergoes reduction.
This reaction is redox reaction.
In this reaction, oxidation number of Ba increases from 0 to +2 . So, Ba undergoes oxidation. The oxidation number of Cl decreases from 0 to -1. So, Cl undergoes reduction.

2) 

From this above reaction, it is clear that Aluminum undergoes oxidation and silver undergoes reduction.
Due to this, this reaction is redox reaction.

In this reaction, oxidation number of Aluminum increases from 0 to +1. So, aluminum undergoes oxidation. The oxidation number of silver decreases from +1 to 0. So, silver undergoes reduction.

3)

In this reaction, Mg undergoes oxidation and Br undergoes reduction.
This reaction is redox reaction.
The reactions 1, 3 and 4 are redox reactions.
In this reaction, oxidation number of Mg increases from 0 to +2 . So, Mg undergoes oxidation. The oxidation number of Br decreases from 0 to -1 . So, Br undergoes reduction.

Hence all the above reactions are redox reactions.

The temperature at which water boils depends mainly on air pressure.

3 + 5 + 6  = 151872

3x5, 3x6, Rev of (3x5 + 3x6 - 6) 

5 + 5 + 6  = 253094

5x5, 5x6, Rev of (5x5 + 5x6 - 6)

Similarly,

9x4 = 36

9x7 = 63

So 36 + 63 = 99

From 99 - 7 =  92

Reverse of 92=29

Hence, 9 + 4 + 7 =  366329.

Laissez-faire is simply a way to describe a government's hands-off approach to economic policies. This approach was particularly prevalent in the United States at the turn of the 20th century, which led to numerous issues within American manufacturing.

There are many outcomes of laissez-faire economic policies. Some of the outcomes of laissez-faire economics were:

* Businesses pay workers low.

* Pollution of air and water.

* Poverty traps that cannot be escaped through free choice. 

* General glut that results from overproduction or underconsumption

* Monopoly power that emerges naturally in the market and allows businesses to exploit consumers. 

* Exploitation of the working class that pushes wages down to subsistence and compels laborers to work in harsh and unsafe conditions. 

* External economies that generate situations where desirable goods are underproduced on the market, and undesirable goods are overproduced on the market. 

* Public goods that are not supplied by the market due to free-rider problems.

Beavers Can Hold Their Breath for 15 Minutes Underwater.

The behavior of beavers means that they need to be able to remain underwater for several minutes at a time.

Radio waves have much longer wavelengths and lower frequencies than do visible light waves. In contrast, X-rays have much shorter wavelengths and higher frequencies. 

Ultraviolet Light (UV). part of the electromagnetic spectrum that consists of waves with frequencies higher than those of visible light and lower than those of x-rays.
