EXPLANATION OF THE CORRECT ANSWER

The formulation of a research problem involves putting into context all the variables related to a particular situation, a phenomenon or a process that requires attention for its improvement, efficiency or understanding.
The fragment describes the problems related to irritable bowel syndrome, that is, the relevance of the condition in Mexico is contextualized based on its recurrence rate, the type of population it affects and the immediate consequences it generates. Therefore, the correct answer is D.

EXPLANATION OF THE CORRECT ANSWER

The criteria to adequately pose a research problem are 3: Express a relationship between 2 or more concepts or variables, be formulated as a question, clearly and without ambiguity, and imply the possibility of an empirical test, that is, the feasibility of being observed in the “single and objective reality.”

EXPLANATION OF THE CORRECT ANSWER

The objectives of a research project must be written starting with infinitive verbs, be clear and concise, propose achievable actions, and focus on achievements and not on processes or activities. Therefore, the correct answer is part d).

EXPLANATION OF THE CORRECT ANSWER

The correct answer is part a) because the theoretical value is the contribution of the research to other areas of knowledge, the transcendental importance or the results that could be applicable to other phenomena.

EXPLANATION OF THE CORRECT ANSWER

According to the succession of narratology by Luz Aurora Pimentel and Javier del Prado Biezma, every story is made up of organizational units such as time, space, actions. In the event that time is not evidenced with temporal units that demonstrate it (a year, a day, afternoon, night, hours, minutes, moments), the construction of the story through actions must be resorted to. Considering this, Luis Brito's story begins by stating an apparent stillness "Now rest and sit down" that is interrupted with the enunciation of a salesman and this is followed by a credit agreement, which in turn has as a consequence that the character (in second person) give an account of new fashions. The final subjunctive paragraph “thus” introduces a conclusion about the fact.

EXPLANATION OF THE CORRECT ANSWER

Textual cohesion is the union that a text has internally, that is, between the words, sentences and ideas of a piece of writing to ensure its coherence and easy understanding. One way to maintain textual cohesion is to avoid repetition of the same word as much as possible.

In the previous text we can see the repetition of many words, therefore, it does not have cohesion.

EXPLANATION OF THE CORRECT ANSWER

Coherence is the property of the text that allows it to be interpreted as a unit of information and is built through the selection and organization of information, that is, the secondary ideas of the text provide relevant and non-contradictory information to reach the idea. main or topic so that it is simple to understand the global meaning of the communication of the text.
The correct answer is part d) since it is incongruous for you to like a series if you have not been able to see it. It is necessary to have seen it to be able to make a judgement.

EXPLANATION OF THE CORRECT ANSWER

The gerund is the impersonal form of a verb and is characterized by having the constant endings -ando, -endo. In general, the gerund within a sentence fulfills the function of adverbs (word that modifies the verb, adjective to another adverb) and expresses an action simultaneous or prior to that of the main verb, but never later.
The use is incorrect because the gerund estar is fulfilling the function of an adjective (word that modifies the noun) since it is modifying the noun dog. The gerund never modifies nouns.

EXPLANATION OF THE CORRECT ANSWER

The gerund is the impersonal form of a verb and is characterized by having the constant endings -ando, -endo. In general, the gerund within a sentence fulfills the function of adverbs (word that modifies the verb, adjective to another adverb) and expresses an action simultaneous or prior to that of the main verb, but never later.
The correct answer is part c), since the gerund found in the text (leaving out) is expressing an action after that of the main verb, which is a misuse of the gerund.

EXPLANATION OF THE CORRECT ANSWER

The correct answer is part a) because the other options present errors in the agreement between the subject and the predicate, that is, they contain solecisms. A solecism is an error of agreement (gender or number), of regime (misuse of prepositions) and of composition (misuse of pronouns) in the structure of the sentence.

EXPLANATION OF THE CORRECT ANSWER

Amphibology is a language vice in which the phrases or words used give rise to more than one meaning or interpretation, therefore, the correct answer is part d), since it is not clear who had a bad time, whether the dog or the boyfriend.

EXPLANATION OF THE CORRECT ANSWER

The correct answer is part b) because it is the only one that expresses only a single meaning of interpretation. All other subsections leave room for further interpretation. For example, in a) it is not known if Pedro is a dwarf or if the dwarf belongs to Pedro. On the other hand, in c) it is not clear what he will lend and in d) the delicious food could be from the cinema or the restaurant.

EXPLANATION OF THE CORRECT ANSWER

Capital letters are used to distinguish proper names (nouns that particularize a being) from common names. In the previous case, the proper names are those of the festivities and those of the ages or periods, while the positions are common. Prepositions or articles are prepositions and articles and not names, therefore, they are written with lowercase letters. So, the correct answer is part a).

EXPLANATION OF THE CORRECT ANSWER

The correct form of the text is The President of the Republic seeks to change the laws this Monday, so I ask you, sir, to make your homeland as a Mexican (section c). Capital letters are used to distinguish proper names (nouns that particularize a being) from common ones, therefore, only “Republic” (Mexican) requires the use of capital letters. The words “president”, “laws”, “sir” are common names, while the word “Mexican” is a demonym (a word that denotes a relationship with a geographical place), so they do not require the use of capital letters.

EXPLANATION OF THE CORRECT ANSWER

The correct answer is part c) because the fundamental function of capital letters in Spanish is to distinguish proper names (nouns that particularize a being) from common names; Therefore, by particularizing and consequently hierarchizing the names, they facilitate the correct understanding of the discourse. Subsection a) is incorrect, since capital letters must always be accented when required. Subsection b) is incorrect since the names of sciences or subjects are only capitalized when we refer to them as subjects of study, and especially in academic contexts. Finally, part d) is incorrect, since the use of capital letters responds to spelling rules and not for extratextual purposes.

EXPLANATION OF THE CORRECT ANSWER

The correct answer is part a) since thanks to the comma it is clear that “boys and girls” is a vocative (whom we refer to in a sentence without being the grammatical subject of it) and the communicative intention of the sentence is call them to eat. If the comma is omitted, the meaning changes and instead of calling them, it is expressed that what will be eaten will be the boys and girls: Let's eat boys and girls.

EXPLANATION OF THE CORRECT ANSWER

The correct answer is part b), since when the vocative (whom we refer to in a sentence without being the grammatical subject of it) is always linked with commas to the rest of the sentence. If it is at the end of an interrogative sentence, it is placed inside the question marks, but if it is at the beginning of the interrogative sentence, it is placed outside the question marks; therefore, option a) is incorrect. Option d) is incorrect since the comma is between the subject of the predicate within the sentence and a comma should never be placed between them and option c) is incorrect because the as is superfluous, in this case, with the use of parentheses are enough.

EXPLANATION OF THE CORRECT ANSWER

A tripthong is the sequence of three vowels that are part of the same syllable. For a tripthong to exist, two unstressed closed vowels (i, u) must be combined and, in the middle of these, an open vowel (a, e, o). The sequences of closed vowel + open vowel + closed vowel when one of the two closed vowels is stressed are not tripthongs in Spanish. What there is in those cases is a hiatus followed by a diphthong, when the first closed vowel is stressed: viviris (vi - ví - ais); or a diphthong followed by a hiatus, when the second closed vowel is stressed: nail cleaner (lim - pia - ú - ñas), therefore, the correct answer is option C.

EXPLANATION OF THE CORRECT ANSWER

1) He (pronoun) has an accent.
2) Se (reflexive pronoun) does not have an accent.
3) If (adverb of affirmation) has an accent.
4) My (possessive adjective) does not have a song.
5) Mas (adverb of quantity) has an accent.
6) If (conjunction that expresses condition) does not have an accent.

Therefore, the correct answer is A.

EXPLANATION OF THE CORRECT ANSWER

Segment [6] of the text indicates that 50% of those killed in traffic accidents are pedestrians, cyclists and motorcyclists; Therefore, the remaining 50% are motor vehicle drivers.

EXPLANATION OF THE CORRECT ANSWER

The text indicates that 3 out of every 4 deaths from traffic accidents correspond to people of the male sex, that is, they represent 75%. The annual total of deaths is 1 million, that is, 24%. Then, the 100% of deaths that correspond to the male sex must be obtained in numerical representation. Thus: .75 x 75 million = 1.24 thousand people correspond to the masculine dry.

EXPLANATION OF THE CORRECT ANSWER

The text mentions that “[…] results in the darkening that forms the crust of any bakery product. […] When in contact with gluten, sugar breaks down this protein and, by absorbing liquid, maintains a soft and moist texture in the cake. Another thing you should know is that when sugar is mixed directly with solid butter, the sugar crystals help draw air into the mixture, and when the cake is cooked in the oven, these air pockets expand causing it to puff up. ”.

EXPLANATION OF THE CORRECT ANSWER

Expository texts are those that explain and transmit information objectively with clear and objective language so that the reader understands and assimilates a topic.

EXPLANATION OF THE CORRECT ANSWER

Expository texts are those that explain and transmit information objectively with clear and objective language so that the reader understands and assimilates a topic.

EXPLANATION OF THE CORRECT ANSWER

The main idea summarizes the content of the paragraph in a short statement and if it is omitted, the paragraph loses all its meaning. The main idea expresses the essential feature of the text and a series of secondary ideas complement it as shown in the image:

EXPLANATION OF THE CORRECT ANSWER

A title is the name assigned to something specific in order to identify the information to which it refers depending on the field to which it is directed. The titles not only fulfill the purpose of naming, but also of attracting the reader's attention, since it is generally the first thing that is read. In this case, since it is a popular science text, the author not only seeks to transmit information, but also seeks to do so in a pleasant way. That is why the title is playful and contains a play on words.

EXPLANATION OF THE CORRECT ANSWER

The hairy ball theorem only corresponds to three-dimensional spheres and the figure in image b) is not.

EXPLANATION OF THE CORRECT ANSWER

EXPLANATION OF THE CORRECT ANSWER

Argumentative texts are those whose purpose is to influence the recipient by provoking a reaction or response, as in this case.

EXPLANATION OF THE CORRECT ANSWER

The introduction is where the context of the text is located and may contain a summary of what will be explained or developed in the body of the text, that is, it is where the reader becomes familiar with the topic; The development is where the topics anticipated in the introduction are presented, and the conclusion is the final part of the work in which a brief summary of the main points addressed in the work is made, the results are presented and the most important findings are highlighted. .

EXPLANATION OF THE CORRECT ANSWER

The conclusion of a literary text is where the result of the transformation or complication (knot) is exposed; it is the new situation of balance that can be encompassed in the word "after." Therefore, what happens after the knot is that the narrator is no longer liked by the neighbor because she stole his cat.

EXPLANATION OF THE CORRECT ANSWER

The word imaginatively means that something is related in an imaginary, fantastic, fictitious, invented or unreal way or manner and fantastically means feignedly, without reality.

EXPLANATION OF THE CORRECT ANSWER

The inference consistent with the text is that the narrator's neighbor lives alone because the environment, character, and narrated actions of the neighbor in the story suggest that he lives alone.

EXPLANATION OF THE CORRECT ANSWER

The author, more than telling a story, seeks to show a playful facet of literature, where the important thing is not what she tells but how she tells it and in this case, she does so through word play.

EXPLANATION OF THE CORRECT ANSWER

According to the text, the narrator says that she believes that the cat is black due to the adverse reaction of some of the people who imagine they see it passing by, so it is inferred that due to the superstition that black cats bring evil. Luckily, people get scared.

EXPLANATION OF THE CORRECT ANSWER

The approach is the presentation of the context that precedes the central action of the story (characters, space and time). It is the initial situation that refers to everything that can be included in the word “before.”

EXPLANATION OF THE CORRECT ANSWER

The main idea of ​​a text is one that expresses in a very synthetic way what the author wants to convey. In this story, the author, rather than telling a story, seeks to be complicit with the reader through the playful form of literature by not making it clear whether everything she tells is real or imagined, therefore, the main idea of ​​the story Story is imagination as a starting point for reality.

EXPLANATION OF THE CORRECT ANSWER

Thrombocytopenia is defined as a decrease in the absolute number of platelets in the peripheral blood below 150.000 per µL (reference value: 150.000 to 450.000 per µL). Medicine & Laboratory 2007; 13: 111-152, 2007.

EXPLANATION OF THE CORRECT ANSWER

The human body is made up of different types of cells and each of them has a specific function. The cells that give rise to all these types of specialized cells are stem or stem cells. Stem cells can divide unlimitedly and self-renew to produce more stem cells without losing their potential or to give rise to different types of specialized cells.
Totipotent cells are capable of generating a complete embryo and giving rise to embryonic and extra-embryonic tissues. Such is the case of fertilization, a process by which a cell is generated: the zygote, a paradigm of totipotent cell, which will give rise to all the cells of the embryo and subsequently, to those of the adult.

EXPLANATION OF THE CORRECT ANSWER

Ecological succession (also known as natural succession) is called the evolution that occurs naturally and causes an ecosystem, due to its own internal dynamics, to replace the organisms that make it up. The term refers to its essential aspect in the replacement of some species by others over time.

EXPLANATION OF THE CORRECT ANSWER

Abiotic factors are the components of ecosystems that do not have life and among the most important we can find water, temperature, light, pH, soil, humidity, oxygen and nutrients.

EXPLANATION OF THE CORRECT ANSWER

The discovery of fossils constitutes solid support that animals were not created suddenly, but rather emerged over time through the process of evolution. If all species had been created simultaneously, we would not expect to find the fossil record of animals such as trilobites, seed ferns or dinosaurs.

EXPLANATION OF THE CORRECT ANSWER

The haploid cell is one that contains a complete set or half of chromosomes. In Reproductive cells, such as the eggs and sperm of mammals, the asexual stage of fungi, bryophytes, and some algae, they contain a single set of chromosomes, while the rest of the cells of a higher organism usually have two sets of them. . When the gametes join together during fertilization, the fertilized egg contains a normal number of chromosomes (2n), that is, it is a diploid cell.

EXPLANATION OF THE CORRECT ANSWER

The color of a human being's eyes is a genetic expression that has several possibilities, among which are the different shades of eye color due to genetic diversity. If we only allowed those people with brown eyes to reproduce, after a few generations we would have lost this genetic diversity that gives rise to the other eye colors.

EXPLANATION OF THE CORRECT ANSWER

Biological classification or Whittaker Classification is the way used by scientists to identify and group living beings according to their characteristics. Robert Whittaker proposed a classification scheme with five kingdoms by considering the following criteria: cell type (prokaryotes and eukaryotes), level of organization (unicellular or multicellular), type of nutrition (autotrophic or heterotrophic) and type of reproduction ( sexual or asexual).

EXPLANATION OF THE CORRECT ANSWER

The photosynthesis process is divided into two stages or phases. The light phase where solar energy is converted into chemical energy from the breakdown of a water molecule (H2O) that releases O2 and the electrons are transferred by photosystems II and I to ultimately produce ATP and NADPH, the which will later be used in the dark phase to produce glucose molecules.

EXPLANATION OF THE CORRECT ANSWER

Facilitated diffusion of ions is carried out through channels formed by transmembrane proteins or an assembly of proteins embedded in the plasma membrane.
These proteins form a channel through which the ion can pass down its concentration gradient. In facilitated diffusion, no energy (ATP) is required and the cell can open or close the channel.
