La respuesta correcta para esta pregunta abierta es la siguiente.
Desafortunadamente no mencionas el país donde vives, para redactar el ensayo tomando en cuenta los valores y cultura de ese país. Sin embargo, te pongo el ejemplo de mi país. Tu ajusta las ideas al tuyo. Deseo que te sirva.
Uno de los más grandes atributos que tenemos los Mexicanos es nuestra reconocida variedad cultural, lo cual nos da una identidad única en el mundo.
Somo un país con una de las historias más ricas del planeta, ya que somos descendientes de civilizaciones tan antiguas como la Olmeca y la Tolteca, además de los grandes imperios Maya y Azteca, dos grandes culturas de Mesoamérica.
Cada región en los 32 estados del país, es un México diferente. Lo que nos une es esa preciosa bandera tricolor, con nuestro símbolo patrio: un águila devorando una serpiente.
Somos un país donde se encuentran muchos de los sitios arqueológicos más importantes de las civilizaciones antiguas. Por ejemplo, el mundo Maya: Chichen Itza(petrimonio de la Humanidad por parte de la UNESCO), Palenque, Uxmal, Tulum, entre muchos otros. O el sitio arqueológico de Cholula, con la pirámide cuya nase es la más grande del mundo. En Oaxaca está el sitio arequológico de Monte Albán. Y por su puesto, la gran ciudad de los dioses, Teotihuacán, con sus imponentes pirámides del Sol, la Luna, y el Quetzalcoatl.
Nuestra comida es reconocidamundialmente por su sasón, sabor, y variados ingredientes. La Yucateca y sus papatzules o huevos motuleños. ¡Qué decir de la cochinita pibil! La Poblana con su riquísimo mole, cemitas o chalupas. El cabrito en el estado de Nuevo León. En fin, no hay estado en donde no haya una receta propia para cocinar enchiladas, tacos, sopes, tlacoyos, huaraches, tostadas, tlayudas, o tamales.
No cabe duda que los Mexicanos nos sentimos orgullosos de 600 años de historia, luchas, independencia y la solidaridad que nos caracteriza como país.
Which of the following best supports the endosymbiont theory that present-day eukaryotic cells are descendants of a successful symbiotic relationship between a host cell and an engulfed prokaryote?
A. Chloroplasts and mitochondria replicate in a similar manner as some prokaryotes.
B. Chloroplasts are necessary for photosynthesis reactions in plant and bacteria cells.
C. Mitochondria and chloroplasts are able to produce ATP molecules to be used by the cell.
D. Mitochondria use proteins and nutrients produced in other regions of the eukaryotic cell.
Answer:
A. Chloroplasts and mitochondria replicate in a similar manner as some prokaryotes
Explanation:
Endosymbiont theory deals with how eukaryotic organisms were formed from prokaryotic organisms. Prokaryotes such as Bacteria were documented as the first form of life on earth through fossil records before eukaryotes came into light.
Organelles such as Chloroplasts and mitochondria replicate in a similar manner as some prokaryotes. This supports the endosymbiont theory that present-day eukaryotic cells are descendants of a successful symbiotic relationship between a host cell and an engulfed prokaryote

Which is the FALSE statement about this blood pressure measurement? 147/92 A. 92 is the diastolic number. B. 147 is the systolic number. C. This is a high blood pressure measurement. D. This is a normal blood pressure measurement.
Answer:
The false statement is - option D.
Explanation:
The lower value is known as diastolic number which is the pressure in the arteries when the heart takes rest in between two consecutive heart beats. Diastolic value shows the pressure of arteries when heart fills with blood.
The upper value or number is known as the systolic number, it is the pressure value of arteries of an individual during the contraction of hear. The normal blood person of a health person is range from 80/60mmhg to 120/90 mmhg, above this range is considered as high blood pressure.
Thus, the false statement is - option D.

If the number of cigarettes smoked increases, then the risk for lung cancer increases. Independent variable: _______ Dependent variable: _______ If the number of sharks swimming in a coastal region increases, then the number of shark attacks on humans will also increase. Independent variable: _______ Dependent variable: _______ If the amount of milk a person drinks increases, the strength of his or her bones will stay the same. Independent variable: _______ Dependent variable: _______
Complete Question:
Part A: Identifying Variables
Read the following hypotheses and identify the variables.
If the number of cigarettes smoked increases, then the risk for lung cancer increases.
Independent variable: _______
Dependent variable: _______
If the number of sharks swimming in a coastal region increases, then the number of shark attacks on humans will also increase.
Independent variable: _______
Dependent variable: _______
If the amount of milk a person drinks increases, the strength of his or her bones will stay the same.
Independent variable: _______
Dependent variable: _______
Answer/Explanation:
Dependent variables are variables that is dependent on the independent variables. That is, it is the variable that changes as the independent variable changes.
Depedent variable is the main interest if a researcher. It is the variable that is measured in a research work.
In the above given hypotheses, the dependent and independent variables are shown below:
1. "risk for lung cancer" is dependent on the "number of cigarettes smoked".
"Risk for lung cancer" => dependent variable
Number of cigarettes => independent variable
2. "number of shark attacks on humans" is dependent on "number of sharks swimming".
Dependent variable => number of shark attacks on humans
Independent variable => number of sharks swimming
3. Dependent variable => strength of bone
Independent variable => amount of milk a person drinks
Answer:
Lab: Heart Rate
Part A: Identifying Variables
The dependent variable happens as a result of values/changes associated with the independent variable.
Independent variable: number of cigarettes smoked
Dependent variable: risk for lung cancer
Independent variable: number of sharks swimming in a coastal region
Dependent variable: number of shark attacks on humans
Independent variable: amount of milk a person drinks
Dependent variable: the strength of his or her bones
Part B: Heart Rate
Hypothesis: If I hold my breath for 30 seconds, then my heart rate will
(choose 1) increase/decrease.
Independent variable: holding my breath
Dependent variable: heart rate
Part C:
The heart rate decreases because oxygen exchange in the lungs decreases.
This depends on what you chose for heart rate in the hypothesis. If you said the heart rate decreases after holding your breath, and the results showed the heart rate decreased, then the hypothesis is supported. If you said the heart rate decreases after holding your breath, and the results showed the heart rate increased, then you refuted the hypothesis.
Heart rate can change due to an increase or decrease in activity, moving positions such as sitting and standing, and emotions.
Example: Increase in activity—jumping jacks
Hypothesis: If I do five jumping jacks, then my heart rate will increase.
Test hypothesis. You can use the average resting heart rate from the previous experiment. If you do an experiment with an increase in physical activity like jumping jacks, then your data will reflect an increase in heart rate because the body requires more energy, which requires more oxygen, increasing the overall flow of blood in the body.
Support or refute the hypothesis based on the results. The hypothesis is supported if it aligns with the observed results. The hypothesis is refuted if the results don’t match the statement based on the variables.
Testing more than one variable at a time makes it difficult to interpret the results and support or refute the hypothesis. With one variable, the results can be associated with changes to that variable. To get the most reliable data to support or refute a hypothesis, an experiment should be completed several times to see if the results show the same trends.

According to Piaget, children have acquired the cognitive skill of conservation when they're able to
Answer:
The question lacks options, the options are:
A. understand the viewpoint of other people.
B. realize that the term heavy describes an object one way and the term big describes it another way
C. understand that six ounces of liquid in a jar and six ounces in an elongated tube are equal.
The answer is C
Explanation:
Piaget proposed the theory of cognitive development, which talks about how human intelligence is developed. Piaget worked with Children because he believed they played a significant role in the development of cognitive intelligence. Based on his work, he proposed four stages of cognitive development viz: sensorimotor, preoperational, concrete operational and formal operational stages.
However, in the preoperational stage, Piaget described children between ages 2-7 as being in this stage of cognitive development where they are yet to comprehend mental logic. One characteristics of this stage is CONSERVATION, which is the ability to know that changing a substance's appearance doesn't change the properties of that substance. Piaget proposed that Children between the ages of 2-7 lacked this conservative characteristics.
He performed an experiment where he used two beakers with the same amount of liquid. He then emptied the contents of one of the previous beakers into a new beaker with different shape (longer). Piaget was able to notice that Children at the pre-operational stage were unable to understand that the contents of the two beakers (longer one and previous beaker) were still the same despite the beaker has been changed.
Hence, according to Piaget, a child has acquired the cognitive skill of conservation when he/she is able to understand that six ounces of liquid in a jar and six ounces in an elongated tube are equal.
What are emergent properties?
Answer:
Emerging properties may arise by transient interactions such as individual organisms building a population. Human interaction in populations leads to the emergence of language, poetry, musical composition, and art. When populations of different species interact, communities form. Many emergent properties are the result of interactions between species in communities.
Emergent properties are characteristics of a system that do not exist in any of its constituent parts individually but originate as a result of interactions between those parts.
What does the characters indicate at ?These characteristics are frequently intricate and challenging to forecast. Emergent characteristics are a crucial idea in several disciplines, including physics, chemistry, and biology.
Emergent qualities in biology can be observed in an organism's behaviour. For instance, a flock of birds' behaviour is an emergent characteristic of the individual birds that make up the flock.
The behaviour of the flock is a product of interactions among the individual birds and is not exhibited by any one individual bird. Similar to this, a school of fish's behaviour is an emergent characteristic of each fish.
Emergent features in chemistry can be observed in how molecules behave. An emergent attribute of a substance's individual molecules, for instance, is the substance's boiling point. The boiling point is not a property of any one molecule, but rather the outcome of interactions between the molecules.
Particle behaviour in physics exhibits emergent features. An emergent attribute of a material's individual particles, for instance, is the material's electrical conductivity.
The interactions between the individual particles produce the electrical conductivity, which is not a property of any one of the individual particles. As a result, emergent properties are characteristics of a system that develop.

Drag each label to the correct location on the chart. Classify each process as weathering or erosion. PLEASE HELP me (I'm stuck) NO homo THOO
Lets do numbering of the labels to make labelling clear.
1. The Colorado River carves land in Arizona to form the Grand Canyon.
2. Cracks form in a sandstone wall surrounding a house.
3. A marble statue near the science museum is changing color due to rainfall.
4. After a rainstorm, soil and rock pieces litter the roadways.
5. The sand dunes in the Sahara Desert are changing shape.
Answer:
Weathering:
2. Cracks form in a sandstone wall surrounding a house.
3.A marble statue near the science museum is changing color due to rainfall.
Erosion:
1. The Colorado River carves land in Arizona to form the Grand Canyon.
4. After a rainstorm, soil and rock pieces litter the roadways.
5. The sand dunes in the Sahara Desert are changing shape.
Explanation:
Weathering and erosion, in both the processes rocks are broken down into particles but both the processes are different from each other. Weathering can be physical, chemical or biological process in which rock particles degrade without any movement while erosion is purely a movement of sediments in which particles move from one place to another under the influence of water and wind.
So, on the basis of this difference we can classify each label to the correct location:
Weathering (no movement of particles after degradation):
2. Cracks in a sandstone wall of a house.
3. Changing color of marble statue due to rainfall.
Erosion (Movement of particles from one place to another):
1. Formation of Grand Canyon, when the Colorado River carves land in Arizona.
4. Soil and rock pieces litter on roadways after rainstorms.
5. Changing shape of dunes in sahara desert.
Answer:
weathering - colorado river carves land in arizona to form the grand canyon. cracks form in a sandstone wall surrounding a house. a marble statue near the science museum is changing color due to rainfall
erosion - after a rainstorm, soil and rock piees litter the roadways. the sand dunes in the sahara desert are changing shape.

What is chromosomes?Write in brief about the structure of a chromosome.must include all points with explanations
Answer:
Please find the detailed explanation below
Explanation:
A chromosome is thread-like material that carries the long strands of the genetic material (DNA), which in turn carries the gene. The chromosome is the found form of nuclear material in the nucleus.
Due to the long nature of the DNA molecule, they cannot fit into the cell. Hence, to ensure they fit, the cell wraps the DNA molecule around a set of protein called HISTONE proteins to form a NUCLEOSOME. Each nucleosome is made up of DNA coiled around a set of 8 proteins called HISTONE OCTAMER. The nucleosome structure becomes more compacted and further wound around the histone to form a CHROMATIN. This chromatin then undergoes condensation to form the visible CHROMOSOME structure.

Why is digestion of fats difficult as compared to that of other nutrients?
This is because fats are insoluble in water and therefore are more difficult to digest than any other nutrients. They also present as large globules.
Hope that helped!!! k
Answer:
Fats take longer time to digest than carbohydrates. Fats can't be digested easily as its insoluble in water and are presented as large globules. The bile juice that gets secreted breaks down the fat from bigger droplets into smaller ones.

Consider a system in which low levels of protein "Q" triggers production of hormone A. The reaction of target cells of hormone A is to produce and release hormone B, which stimulates production of hormone C. In response to hormone C, the target cells up-regulate protein Q. In this scenario we see an example of _____.
Answer:
Negative feedback
Explanation:
Negative feedback is produced when a mechanism is amplified through an inverse loop, which tends to reduce the fluctuations in the system. In this case, the negative feedback mechanism represents a homeostatic response of the body where the release of a target hormone (hormone C) decreases in response to the increase of a protein (protein Q) upstream in the signaling pathway. Therefore, in this scenario, it is expected that negative feedback causes a decrease in hormone function.
A water strider (which can walk on water)has legs that are coated with a hydrophobic substance. What might be the benefit? What would happen if the substance were hydrophilic?
Answer:
The water striders are the species, which are about half an inch in length and exhibiting a thin body with three legs set. The legs of water striders exhibit small hairs, which helps in repelling water and holding air. The water striders by repelling water stand on the surface of the water and the captivated air permit them to float and move readily.
The legs of water striders are coated with hydrophobic substances, which helps in repelling water and assists in keeping the terminals of the legs from getting coated with water. In case, if the legs of the species were coated with a hydrophilic substance, then water would be drawn up by the legs and would make the striders break through the surface and thus would have a tough time to walk on water.

A cell has a 5\%5%5, percent salt concentration. It is placed into a solution with a 0.5\%0.5%0, point, 5, percent salt concentration. What will happen to the cell?
The question is not clear, so the clear question is as follows:
A cell has a 5 percent salt concentration. It is placed into a solution with a 0.5 percent salt concentration. What will happen to the cell?
Answer:
Cell will get swelled and burst
Explanation:
When a cell is placed in a solution with less concentration, then the solvent particles move from lower concentration to higher concentration through a semipermeable membrane and the process s called osmosis.
In this case also, the cell has higher concentration and the solution has less, so water will move into the animal cell, causing it to swell and burst after some time.
Hence, the correct asnwer is "Cell will get swelled and burst".
Answer:
Water will move into the cell, causing it to swell.
Explanation:
The cell has higher concentration of solute and a lower concentration of water than the solution it is placed in. This means that water will move into the cell, causing it to swell and ultimately burst.
