Refer to the chart of amino acid structures to help answer this question. Which four statements about amino acids are true? Ser
Bad White [126]

Answer:

1. Ser and Gln are polar amino acids.

2. The Leu side chain does not form hydrogen bonds with other amino acids.

3. Phe can undergo oxidation to form Tyr.

4. Lysine has one stereocenter (chiral center).

Explanation:

Serine and glutamine are the polar amino acids with uncharged side group. Serine has a "CH2OH" group as its side chain and the presence of hydroxyl group makes it a polar amino acid. Glutamine is one of the amides derived from other amino acids present in proteins.  

Leucine is a nonpolar amino acid with an aliphatic side chain and tends to cluster within the proteins to stay away from the surrounding watery medium. Its aliphatic R group does not form any hydrogen bonds to other amino acids.  

Phenylalanine is a nonpolar amino acid with an aromatic R group. Oxidation of aromatic R group of phenylalanine converts it into tyrosine which has an additional hydroxyl group in its side chain.

The chiral center is the carbon to which four different functional groups are bonded. The central alpha carbon atom of lysine is bonded to an amino group, carboxyl group, a hydrogen atom, and one positively charged R group which in turn makes it a chiral center.

How have anthropologists attempted to address the negative effects of massive cultural change imposed on less powerful groups by
Mkey [24]

Explanation:

Mass culture is a set of cultural objects, goods or services, produced by cultural industries, which are aimed at a diverse audience.

According to critics, such as Adorno, the mass follows the same thing. According to the Frankfurt School, mass culture is the main means through which capital would have achieved its greatest success. Then, the whole system of mass production of goods, services and ideas would have accepted, in general terms, the model imposed by the capitalist system by the hand of consumerism, technology and rapid satisfaction. This culture is defined through the mass media from the nineteenth century (printing, radio, cinema, television, and even today with the Internet). From this appear the mass societies that are shaped by a society of individuals aligned to capitalism, where the bourgeoisie has the power to introduce products, ideologies, etc. into society. and thus curtail the freedom of expression of a fully capitalized society.

It is considered as the development of a new model in which differences and inequalities are reinforced with increasingly developed marketing strategies and instruments. Science and knowledge are put at the service of the production of stereotyped values ​​and symbols.

The three fundamental pillars of this culture are: a commercial culture, a consumer society and an advertising institution
