The long “tail” on a detergent molecule is made up mostly of carbon atoms bonded to other carbon atoms. Why would you expect the

tail to be nonpolar?

Answer:

Detergents are amphilic in nature having hydrophilic head (Polar) and hydrophobic long tail (non-polar).  The nonpolar hydrophobic tail is mostly made up of of carbon atoms bonded to other carbon atoms.

Tail plays a very important function of detergent by break down the surface tension that exists between grease and water. The tail is required to be non-polar because it attaches to fat (grease) or dirt and repels water molecules and form micelle, which get rinse of with detergent. The non-polar end then move towards the surface and weakens the hydrogen bonds in water, which breaks the break in the surface tension of the water.

Hence, tail of detergent is required to be nonpolar to function by break down the surface tension that exists between grease and water and do the proper cleansing of clothes.

Natasha_Volkova [10]
Known as the cell’s “command center,” the nucleus is a large organelle that stores the cell’s DNA (deoxyribonucleic acid). The nucleus controls all of the cell’s activities, such as growth and metabolism, using the DNA’s genetic information. Within the nucleus is a smaller structure called the nucleolus, which houses the RNA (ribonucleic acid). RNA helps convey the DNA’s orders to the rest of the cell and serves as a template for protein synthesis.

How does the size of the soil particles impact<br> the soil's permeability (movement of water)?
Usimov [2.4K]

Answer:

Water moves by gravity into the open pore spaces in the soil, and the size of the soil particles and their spacing determines how much water can flow in. Wide pore spacing at the soil surface increases the rate of water infiltration, so coarse soils have a higher infiltration rate than fine soils.

How does soil particle size affect permeability?

But permeability is a different thing. It increases as particle size increases. By definition, permeability is a MEASURE OF EASE with which fluids will flow though a porous rock, soil or sediment. ... That means capillarity increase as particle sizes decreases.

<h2>Hey There!</h2><h2>_____________________________________</h2><h2>Answer:</h2><h2>_____________________________________</h2>

\Large\textbf{ACTIVE AND PASSIVE IMMUNITY}

Active Immunity, Immunity which is acquired by the own immune response of the body.

Passive Immunity, Immunity which is acquired and dependent upon the antibodies transported from another person or even an animal. A person's immune system does not acquire or make the antibodies itself. A newborn baby acquires passive immunity from its mother through the placenta.

                            x---------------------------------------------------x

<h2> </h2><h2> \Huge\text{Vaccination:} </h2>

Vaccination is a artificial active immunity. Artificial because the antibodies are not acquired by any natural infection but it is injected into the healthy body of the person. It is Active immunity because the body does not get already made (from other animal) antibodies but it acts on the small amount of the pathogen which is injected in the body and acquires the antibodies itself. So the person acquires antibodies naturally acting on the antigen. Antigen is any foreign agent which triggers the immune system to produce antibodies against it. Vaccines contains antigen which is a harmless form of the bacteria or a virus that causes the disease you are being immunised against. The bacteria or virus are in small proportion and greatly weakened in the vaccine so they just trigger an immune response without causing any real damage. When Vaccine is injected in the body, the immune system starts to make antibodies of different forms against the antigen(Virus or bacteria in the vaccine). When the appropriate shape antibody reacts with the antigen and forms antibody-antigen complex which destroys the antigen. This means that type and shape of antibody is perfect to work against that antigen, then the immune system start forming only those kind of antibodies in great proportion and the Person gets immunised by the vaccine in a natural way.
