Answer:
The <u>biological species concept</u> is not very useful in defining plant species.
Explanation:
The biological species concept says that <em>species are population groups that, in a real or potential way, can reproduce and that </em><em>are reproductively isolated from other groups.</em>
<em>Individuals belonging to a species cannot reproduce with members of other species. </em>
This biological concept has limitations. Its application might present difficulties in concern with asexual reproduction species, such as bacteria, rotifer, cnidarians, plants, and etcetera.
Besides, this concept cannot be applied to the past because it is difficult to deduce reproductive capability between extinct species.
Finally, this concept is not adequate in concern to hybridization zones, something to be expected considering evolutionary processes. This is why this concept has been less accepted by botanists, as some plant species hybridize with other species. For example, species Quercus grisea and Quercus gambelii have overlapping ranges in the southwestern United States. Hybrids showing variation in leaf shape and other traits have been found in many places in this area.

Every living thing makes energy through respiration and plants use solar energy during respiration.
Air moves into the lungs when the air pressure in the lungs is lower than the air pressure outside of the lungs. This occurs when the muscels of the diaphragm contract.
You can see this by breathing in and out deeply. When you breath in you can feel your chest being pushed up and out by your diaphragm. The reason the pressure in the chest is lower is that when you breathe in you are increasing the volume of your chest. As there is the same amount of air in your chest the pressure decreases.
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
