Answer:

It shows how violent the situation was and how scared Enrique was.

Explanation:

The book "Enrique's Journey" by Sonia Nazario tells the true story of a young boy named Enrique on his quest to find his mother who has gone to America in search of work. The story delves into the dangerous and menacing obstacles that migrants like Enrique had to endure and go through to get to the safer land in America. This story is also like an insight into the borderlands that is between America and the South American nations, with migrants coming in masses in the hope of a better and peaceful future.

As seen in the excerpt from the book, the author provides a scene where gangsters threaten and even assault anyone who went as far as to help the authorities identify them. This very act of torturing or using violent means to keep people quiet shows how dangerous life is for the migrants while trying to get to the other side. The characterization in this passage shows the violent scene that migrants have to endure and the emotional fear that people like Enrique were put in.

Answer:

Answer:

Paracentric Inversion

Explanation:

Some of the mutations that occur in chromosomes involve inversions. These imply a structural change that affect the genes´ order in the chromosome.

In the inversion, the chromosome suffers two ruptures, and then it is reconstituted. The problem is that this reconstitution occurs inverted. These two ruptures might occur in the same chromosomic arm, or it might involve the centromere. The first case is known as paracentric inversion while the second case is called pericentric inversion. Note: The exposed example is a product of paracentric inversion, as the centromere is located between C and D genes, and the inversion involves E, F, and G genes.  

During meiosis, when homologous chromosomes mate, and a structure known as inversion loop is formed. The chiasms within them make a place to inviable gametes. The crossover event inside the loop produces create a bridge between the two homologous chromosomes, and the fragment without centromemer is lost. After that, the bride breaks, and the two homologous chromosomes segregates.  The final result is two viable gametes identical to the ones of the progenitors, and two inviable gametes, result of inversion.

A. Speciation

Explanation:

Speciation is how a new kind of plant or animal species is created. Speciation occurs when a group within a species separates from other members of its species and develops its own unique characteristics.

When the genetic drift occurs due to various factors and results in the formation of a new species it is called speciation. Thus, option A is correct.

Speciation is the formation of a distinct species from the original population because of the genetic drift that caused evolutionary changes essential for survival.

The species are separated from their original population leading to variation in the gene pool resulting in reproductive isolation and finally, the new species is formed.

Explanation:

The given question is incomplete as the four possible explanations or options are not provided, however, the correct options are as follows:

A) More ATP is produced per CO2 released in cyclic processes than in linear processes.

B) It is easier to remove electrons and produce CO2 from compounds with three or more carbon atoms than from a two-carbon compound such as acetyl CoA.

C) Redox reactions that simultaneously produce CO2 and NADH occur only in cyclic processes.

D) Cyclic processes, such as the citric acid cycle, require a different mechanism of ATP synthesis than linear processes, such as glycolysis.

Answer:

The correct answer would be - option B

Explanation:

Circular pathways or the cycles are able to carry out two or more than two entry and exit points for the substrate enzyme and products, So it is well suited for amphibolic reactions.

In a linear pathway, one reaction with particular substrate or reactants  and result in products through the pathway completes the pathway, and the second reaction would be an independent event.

In citric acid cycle It is easier to eliminate electrons and gain carbon dioxide from compounds with 3 carbon or more carbon atoms than from a two-carbon compound such as acetyl CoA. pyruvate is 3 C compound while acetyl CoA is two carbon.

Thus, the correct answer is - option B

Answer:

the cell is most likely a plant cell in cytokinesis

Explanation:

Cytokinesis simply means the division of the cytoplasm. It happens after the telophase stage of the cell division and leads to the formation of two distinct cells.

Cytokinesis in animal cells involves the constriction of the plasma membrane from the equator of the cell outward until two distinct cells result. The process starts from the anaphase and continues through the telophase stage of the cell division.

Due to the presence of cell walls in plant cells, cytokinesis does not just involve the constriction of the plasma membrane but the formation of cell plates at the equator of the cell. The cell plate fuses with the plasma membrane, eventually dividing the cell into two with the formation of cell walls between the two membranes of the cell plate.

The cell is most likely a plant cell undergoing cytokinesis.

light microscopy allows the visualization of dynamic processes in living cells light

Explanation:

Light microscopy has a biggest advantage over electron microscopy because it all the visualisation or ability to observe living cells and biological activity such as the uptake of food, cell division and movement. Light microscopy can be use in-vivo staining techniques to visualise the uptake of colored pigments by the cells which cannot be observed with electron microscopy because in electron microscopy the element must be fixed, dehydrated or dead before been visualised . Electron microscope cannot observe living cells and can only observe dead or dry specimens so that electrons can pass through the specimen to be able to observe.

Light microscope has higher penetrating power than electron microscopy thus allows the visualization of dynamic processes in living cells. Therefore, option c is correct.

Microscopy is the technical field of using microscopes to view samples & objects that cannot be seen with the unaided eye.

Light microscopes can also be used to visualize dynamic processes in living cells because it has greater penetrating power than electron. Electron microscopes uses high-energy electrons that would damage the cells.

Electrons have shorter wavelength than visible light, so provide higher resolution than light microscopes.

Electrons have much a shorter wavelength than visible light, and this allows electron microscopes to produce higher-resolution images than standard light microscopes.
