The underlined sentences demonstrate characterization. How does this technique support the author’s purpose?
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:
It shows how violent the situation was and how scared Enrique was.

Asthma is a respiratory disorder that can cause the airways to temporarily constrict, or get narrower. Which function of the respiratory system is most affected by the narrowing of the airways? A. water balance B. air filtration C. heat balance D. gas exchange
Answer:
Answer is D.
Explanation:
Asthma is a chronic inflammation that affects the airways, directly affecting the gas exchange of oxygen and carbon dioxide with the blood.
What is asthma?It is a chronic disease of the lungs that inflames and narrows the airways.
Since this disease causes the airways to become inflamed and swollen, it reduces the amount of air that can move in and out of the lungs (gas exchange).
Therefore, we can conclude that asthma is a chronic inflammation that affects the airways, directly affecting the gas exchange of oxygen and carbon dioxide with the blood.

The table below summarizes Mendel’s results for the F2 generation. Mendel’s Results Plant height 787 tall 277 short Flower color 705 purple 224 white Flower position 651 middle of stem 207 end of stem Pod color 428 green 152 yellow Pod shape 882 inflated 299 constricted Seed color 6,022 yellow x green Seed shape 5,474 smooth 1,850 wrinkled What number should replace the letter x in the “Seed color” row? 152 207 224 2,001
Answer:
2001
Explanation:
This question showcases a table that displays Mendel's results (figures) when he crossed pea plants and observed different characters in the plant. Mendel worked with different phenotypic characteristics in the pea plant.
According to the table, the result were for seven characteristics including height, flower color, flower position, pod color, pod shape, seed color, seed shape. Based on the observation of the number of F2 offsprings that possessed dominant trait and recessive trait for each character, we will notice that it follows an approximate phenotypic ratio of 3:1
1. Plant height 787 tall 277 short (3:1)
2. Flower color 705 purple 224 white (3:1)
3. Flower position 651 middle of stem 207 end of stem (3:1)
4. Pod color 428 green 152 yellow (3:1)
5. Pod shape 882 inflated 299 constricted (3:1)
6. Seed color 6,022 yellow X green
7. Seed shape 5,474 smooth 1,850 wrinkled (3:1)
This 3 dominant : 1 recessive ratio is the ratio got in the F2 offsprings when he observed the seven characteristics in pea plants. Hence, the seed color will also follow the same 3:1 ratio
Therefore, 2001 is the result Mendel obtained in the F2 offsprings for the recessive trait of seed color characteristics in his experiment, which actually depicts the 3:1 ratio. Hence, X (green seed color) is 2001
I believe that the answer is C. 2001

A student draws this model to show how humans evolved from ancestral primates. What are the pros and cons of
this model in regard to the theory of evolution? Explain how you'd make it more accurate. To create a scientifically
credible answer, use a credible website to research human evolution.
Answer and explanation:
The model designed by the student is useful to explain in a simple way the question of the evolution of the homo gender (our gender), mainly in basic education, but it may seem inconsistent at higher educational levels.
Humans and chimpanzees, according to the theory of evolution, descend from a relatively recent (about 7 million years) common ancestor.
These same species, as well as lemurs, baboons and all other primate species, share an ancestor who lived longer. Likewise, there is an even older ancestor that originated primates, bats, whales and all other groups of mammals .
The fact that chimpanzees have a DNA very similar to ours (about 98.5% similarity between code sequences) is because the successive evolutions from this common ancestor were not very drastic, besides the fact that they are in a branch more close to ours from the moment of separation of evolutionary lineages.
A discrete, locally folded unit of protein tertiary structure usually having a specific function best describes __________. A discrete, locally folded unit of protein tertiary structure usually having a specific function best describes __________. a domain a motif a complex quaternary structure
Answer:
a domain
Explanation:
The domains are the basic units of the proteins, they are polypeptide segments (about 30 -200 amino acids) that have a defined tertiary structure and play specific biological functions including, for example, enzymatic and structural activities. Protein domains are evolutionary conserved, it means that these polypeptide segments can be found in phylogenetically related species and share sequence homology. Examples of protein domains include the zinc finger and the helix-turn-helix domains which are involved in protein-DNA interactions of transcription factors.
Drag each label to the correct location. Identify the cell organelles found only in plant cells and those found in both animal and plant cells. nucleus cell wall chloroplast Golgi apparatus cell membrane ribosome
Answer:
Plant cell: chloroplast, cell wall
animal and plant cells: nucleus, cell membrane, ribosome, golgi apparatus
Explanation:
The organelles that are specific to the plant cell only among the listed organelles include chloroplast and cell wall, while those found in both animal and plant cells include the nucleus, cell membrane, ribosome, and golgi apparatus.
The chloroplast contains the green pigment (the chlorophyll) that is present in all green plants. It is the organelle that confers greenness to plants and is therefore absent in animal cells. The rigid cell wall is only found in plant cells and this confers a kind of hexagonal shape to the cell, unlike the animal cell that lacks a rigid cell wall and therefore, shapeless.
All eukaryotic cells, including plant and animal cells, posses nucleus. It is an organelle that houses the genetic materials of the cell and acts as the control center of the cell. The cell membrane is also common to both cell and acts as a selectively permeable membrane to the cells. The ribosome is the organelle responsible for protein synthesis in both plant and animal cells while the golgi apparatus plays an important role in secretory pathway in both cells.

Identify the stage of cellular respiration in which each of the following takes place,
Produces 32 ATP molecules
Creates four ATP molecules, but then gains overall only iwo
Gives off carbon dioxide
Gives off water
Produces two ATP molecules
DON
The given statements correspond to different stages of cellular respiration, which is the process by which cells generate energy from glucose and other organic molecules. The stages of cellular respiration are glycolysis, the citric acid cycle (also known as the Krebs cycle), and oxidative phosphorylation (including the electron transport chain). Let's analyze each statement and identify the corresponding stage:
1. Produces 32 ATP molecules: This statement refers to the stage of oxidative phosphorylation, specifically the electron transport chain. During this stage, electron carriers produced in earlier stages (glycolysis and the citric acid cycle) donate electrons to the electron transport chain, leading to the production of ATP through chemiosmosis. In total, oxidative phosphorylation generates a maximum of 32 ATP molecules.
2. Creates four ATP molecules, but then gains overall only two: This statement refers to the stage of glycolysis. Glycolysis is the initial step of cellular respiration and occurs in the cytoplasm. It involves the breakdown of glucose into two molecules of pyruvate and the production of ATP. In glycolysis, a net gain of two ATP molecules is produced. However, since two ATP molecules are used in the initial steps of glycolysis, the overall gain is only two ATP molecules.
3. Gives off carbon dioxide: This statement corresponds to the citric acid cycle (Krebs cycle). The citric acid cycle takes place in the mitochondrial matrix and completes the oxidation of glucose. During this cycle, acetyl CoA derived from pyruvate is further oxidized, leading to the release of carbon dioxide as a waste product.
4. Gives off water: This statement corresponds to the stage of oxidative phosphorylation. In oxidative phosphorylation, the final electron acceptor is oxygen. As electrons pass through the electron transport chain, they combine with oxygen and hydrogen ions to form water.
5. Produces two ATP molecules: This statement refers to the stage of substrate-level phosphorylation in the citric acid cycle. During the citric acid cycle, one ATP molecule is produced directly through substrate-level phosphorylation in one of the reactions. Thus, in each cycle, two ATP molecules are generated (although later stages of cellular respiration generate more ATP through oxidative phosphorylation).
In summary, the stages of cellular respiration corresponding to each statement are as follows:
1. Produces 32 ATP molecules: Oxidative phosphorylation (electron transport chain)
2. Creates four ATP molecules, but then gains overall only two: Glycolysis
3. Gives off carbon dioxide: Citric acid cycle (Krebs cycle)
4. Gives off water: Oxidative phosphorylation (electron transport chain)
5. Produces two ATP molecules: Citric acid cycle (substrate-level phosphorylation)

In coral reefs, clownfish live unharmed among the poisonous tentacles of sea anemones. The sea anemones protect the clownfish from predation, while the clownfish scare off predators, such as the butterfly fish, which would otherwise eat the anemones. The clownfish may also provide important nutrients to the anemones. This arrangement is an example of which symbiotic relationship
Answer:
The sea anemone and the clownfish live together in a type of symbiotic relationship called mutualism, where both species benefit from the other. The sea anemone offers the clownfish protection and leftover food
The anemone's tentacles provide the clownfish with protection from predators, while the clownfish chase away butterfly fish that would eat the anemone. ... Sea anemones can do very little to control the flow of water across their bodies, and they rely on local currents to bring in oxygen and nutrients.Clownfish perform an elaborate dance with an anemone before taking up residence, gently touching its tentacles with different parts of their bodies until they are acclimated to their host. A layer of mucus on the clownfish's skin makes it immune to the fish-eating anemone's lethal sting.Instead, both species have evolved behaviors that help them avoid being eaten while they graze for benthic algae. Butterflyfish typically swim in pairs near a particular clump of coral. ... An anemone robbed of its clownfish guards will quickly fall prey to the voracious butterflyfish.

If you were assigned the task of constructing a cladogram representing the evolutionary relationship between amphibians, turtles, lizards, snakes, crocodiles, birds, and mammals, what feature could you use as the shared derived trait
Answer:
Four Limbs
Explanation:
Answer:
The four limbs
Explanation:
A shared derived trait involves shared characters that lineages have in common, which have evolved in the lineages leading up to a clade and that sets members of that clade apart from other individuals.
The four limbs is found in virtually all amphibians, turtles, lizards, snakes, crocodiles, birds, and mammals. It might not be seen in snakes now, but historically it is believed that ancient snakes once possessed limbs. This feature is a shared derived trait that exist among the selected clade.
Suppose that an unusually high degree of aurora kinase activity is observed in the cervix. What could we reasonably conclude about C5M treatment efficacy across all cervical cancer cell lines, using this new information and the data within the passage
Answer:
The division of cervical cancer cells will be inhibited
Explanation:
Aurora kinases are a type of serine/threonine kinase enzymes that play critical functions during cell proliferation, and they are recognized to be potential targets in cancer therapy. The benzo[e]pyridoindole (C5M) agent is a hydrosoluble inhibitor of aurora kinases capable of inhibiting cell proliferation. C5M induces mitotic arrest by faulty (no separation) of the sister chromatids during cell division, thereby eventually leading to polyploidy and finally triggering cell death. It has been shown that C5M acts to prevent the entry in mitosis by inhibiting histone 3 (H3) phosphorylation of aurora kinases.
