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
What portion of a pre-mRNA molecule may be cut to be discarded?
ans:- In eukaryote cells the primary transcript (pre-mRNA) is processed. One or more sequences (introns) are cut out.
Answer:
The conversion of ADP to ATP using light energy
Explanation:
Photophosphorylation is a stage in photosynthesis in which ADP is converted to ATP using sunlight energy.
Note that, in photophosphorylation, 2 ATPs are produced
This process is fundamental in maintaining a stable energy level in our eco-system.
Answer:
Transmission Electron Microscope would show a mitochondria’s internal structure in the greatest detail
Explanation:
The TEM is used to visualise the internal structure of the cells. This works when an electron beam of light passes through the object or the sample, it shows a clear presence of the organelles inside the cell. The TEM uses the energetic electron which provides the morphological as well as compositional and crystallographic features of the cell. Its maximum potential is about 1 nanometre. Among the most powerful microscope for studying the internal organelles of the cell TEM is one.
Question:
<em>The diagram shows the potential energy changes for a reaction pathway.</em>
Part 1: Does the diagram illustrate an endothermic or an exothermic reaction? Give reasons in support of your answer.
Part 2: Describe how you can determine the total change in enthalpy and activation energy from the diagram and if each is positive or negative.
Answer:
Part 1: The diagram illustrates an endothermic reaction as the products has a higher potential energy than the reactants do. There is a positive slope of the diagram and there is enough energy to meet the activation energy requirement.
Part 2: You can determine the total change in enthalpy and activation energy from the diagram by the potential energy of the reactants. If the reactants have a high potential energy, then the enthalpy is also high, and if the reactants have a low potential energy, then the enthalpy is low. You can determine if the diagram is positive or negative by knowing if its an endothermic or exothermic reaction. An endothermic reaction is positive because the products are higher than the reactants and a exothermic reaction is negative because the reactants are higher than the products.
