Answer:
Una mutación es el cambio al azar en la secuencia de nucleótidos o en la organización del ADN (genotipo) de un ser vivo,1 que produce una variación en las características de este y que no necesariamente se transmite a la descendencia. Se presenta de manera espontánea y súbita o por la acción de mutágenos. Este cambio estará presente en una pequeña proporción de la población (variante) o del organismo (mutación). La unidad genética capaz de mutar es el gen, la unidad de información hereditaria que forma parte del ADN.2
En los seres pluricelulares, las mutaciones solo pueden ser heredadas cuando afectan a las células reproductivas.3 Una consecuencia de las mutaciones puede ser, por ejemplo, una enfermedad genética. Sin embargo, aunque a corto plazo pueden parecer perjudiciales, las mutaciones son esenciales para nuestra existencia a largo plazo. Sin mutación no habría cambio, y sin cambio la vida no podría evolucionar.

The gluten-free diet was originally intended for people with celiac disease, but it's now become a new fad diet for the general population. Many people state that gluten-free diets are beneficial for people who aren't sensitive to gluten, while others suggest that there's no benefit. Use credible resources to evaluate the argument yourself. Do you think there's sufficient scientific evidence to support the use of a gluten-free diet in people who aren't sensitive to gluten? Provide evidence that supports your argument.
Answer:
hey love! so i actually have celiac so i know a lot about this haha! hope this helps!!
Following a gluten-free diet in the absence of celiac disease may be detrimental to health. Nutritional deficiences: Avoiding foods that contain gluten can lead to deficiencies in essential nutrients, including iron, calcium, fiber, folate, thiamin, riboflavin, and niacin.
Explanation:
In recent years, the gluten-free diet has become more of a fad than a medical necessity. ... The study concluded that more gluten consumption is associated with a lower risk of heart disease, suggesting that those who do not suffer from celiac disease or non-celiac gluten/wheat sensitivity should not avoid gluten. Though many health professionals suggest otherwise, it's safe to follow a gluten-free diet — even for people who don't necessarily need to do so. Cutting out wheat and other gluten-containing grains or products will not cause adverse health effects — as long as these products are replaced with nutritious foods.
Answer:
Explanation:
There’s no benefit to a gluten-free diet for people who aren’t sensitive to gluten. Many websites state benefits of a gluten-free diet. These benefits range from weight loss to improved heart health. None of these sites backed up their claims with scientific research. More credible sites consistently state that there’s no scientific research to back up these claims. Right now, there’s no evidence that supports the benefits of a gluten-free diet in people who aren’t sensitive to gluten.

The cause of humanity's increased water consumption is an increased population. What is the effect?
Option are not provided in the question. The complete question is as following:
The cause of humanity's increased water consumption is an increased population. What is the effect?
A. less potable water, a growing threat to biodiversity
B. more potable water, a growing threat to biodiversity
C. less potable water, a decreased threat to biodiversity
D. more potable water, a decreased threat to biodiversity
Answer:
A. less potable water, a growing threat to biodiversity
Explanation:
The increasing population of human causes increase in water consumption that leads to reduction in portable water, which is a growing threat to biodiversity .
Portable water or freshwater is used for drinking by humans beings along with that it provide habitat to many diverse marine wildlife and they are important to local ecosystems as they provide sources of income and food to humans and other wildlife.
Freshwater or portable water play very important role to control flood and erosion.
So, decrease in portable water result into decrease in biodiversity.
Hence, the correct option is A. less potable water, a growing threat to biodiversity .
Angelina is learning how to build circuits. She starts by connecting a light bulb to a battery with copper wires. In her studies, she reads that the current flows due to a difference in potential energy in the system. Which statement describes what is happening to cause current to flow? A. Voltage is when current flows from lower to higher potential energy. B. Voltage is when current flows from higher to lower potential energy. C. Amperes is when current flows from lower to higher potential energy. D. Amperes is when current flows from higher to lower potential energy.
Answer:
B. Voltage is when current flows from higher to lower potential energy.
Explanation:
Voltage refers to the difference in electric potential between two points. Current in the wire always flow from higher potential to lower potential due to voltage. At the electric source, voltage of current is high but when it moves through wire, the amount of current decreases when it reaches to the other end of the circuit. This is because of the resistance present inside the wire which causes heat energy and some of the current is lost.
The correct answer is option B. Voltage is when current flows from higher to lower potential energy.
What is voltage?
Voltage is the difference in charge, in this case, made by the electrons, that results in electrons flowing from a place of high concentration to one of low concentration. We call the flow of electrons current, and we measure voltage in Volts (V).
What is Amperes?It is a unit that we use to measure the intensity of the current.

Answer:
The gluten free diet is helpful for the people that are sensitive to food with gluten it which occurs due to the celiac disease. It was originally meant for the such people but it becomes a new fad. However, there is no compelling evidence to support that gluten free diet helps in health improvements n non sensitive people.
In other hand there are majority of doctors are against the use of gluten free diet is not good for various body organs like heart. A study concluded that there are lower risk of heart disease in people take more gluten. Doctors and various study suggests that people with no celiac disease should not avoid gluten.

Explanation:
1. yeast is microorganism which is used for large production of alcohol. this alcohol is used in making of wine, beer, whisky as well as industrial spirit.
2. yeast is capable of converting sugar into alcohol .
2. In the example of the white and brown mice, vultures will prey on both colors of mice. However, in
the desert environment, the brown mice are better able to hide from their predators and have an
advantageous trait. What will happen to the color of mice over time?
Answer:
The brown color of mice would become more common in the population of the mice in the desert overtime
Explanation:
In the mice population, since the environment favors the individuals with brown fur color over individuals with white fur color, as it makes them better able to escape from predatory vultures, white mice gets eaten more often. With time, the population of white mice reduces while that of brown mice increases.
Overtime, brown mice leaves more offspring with its trait compared to white mice. As a result of this, the color mice that would be more common in the desert environment would be mainly brown colored mice, while white mice would be few.

What are some ways that the nitrogen cycle overlaps with or influences the oxygen and carbon cycles?
Are any of these interactions between the cycles positive?
Are any negative?
What about when the nitrogen cycle is thrown off balance by the Haber-Bosch process and others like it?
How can that influence the oxygen and carbon cycles?
Are there other cycles involved that have not been mentioned in this question?
What does this discussion suggest about the nature of the Earth as one large system?
Answer:
1. Nitrification occurs when soil microbes convert ammonium into nitrate. Much of the overlap between the carbon cycle and the nitrogen cycle occurs in the soil, in processes conducted by soil microbes. Microbes break down nutrients, build new compounds for their own growth, and eventually die.
The second question im not sure sorry- the positive and negative one ;(
3. Many human activities have a significant impact on the nitrogen cycle. Burning fossil fuels, application of nitrogen-based fertilizers, and other activities can dramatically increase the amount of biologically available nitrogen in an ecosystem. As nitrogen makes up 78% of the atmosphere, there is no shortage of it – it just isn't in a form plants and animals can use.
4. Carbon makes its way through living things as carbon-based compounds, like energy molecules, fats and proteins, eventually cycling its way back into the atmosphere. Nitrogen is mainly found in the atmosphere as well and enters the ecosystems as nutrients for plants. Water, nitrogen and carbon cycles. Carbon moves from the atmosphere and back via animals and plants. Nitrogen moves from the atmosphere and back via organisms. Water moves on, above, or below the surface of the Earth.
5. Carbon cycle, Nitrogen cycle, Nutrient cycle, Oxygen cycle, Phosphorus cycle, Sulfur cycle, Rock cycle, Water cycle.
6. Wind, water, and ice erode and shape the land. Volcanic activity and earthquakes alter the landscape in a dramatic and often violent manner. And on a much longer timescale, the movement of earth's plates slowly reconfigures oceans and continents. Each one of these processes plays a role in the Arctic and Antarctica.
Humans impact the physical environment in many ways: overpopulation, pollution, burning fossil fuels, and deforestation. Changes like these have triggered climate change, soil erosion, poor air quality, and undrinkable water. Earth's surface is the only habitat available to the human race. Understanding the processes by which that habitat has been created and continually altered is important to determine the causes of environmental degradation.

A partial Texas food web is shown. The populations of which organisms will
most likely increase as a result of a disease that suddenly reduced the
population of Texas horned lizards. (12C) *
*See attached digaram for the good web being refffered to
Options:
A. Grasses and ants
B. Ants and grasshoppers
C. Grasshoppers and Texas cottonmouths
D. Texas cottonmouths and red-shouldered hawks
Answer:
B. Ants and grasshoppers
Explanation:
Looking at the partial Texas food web that is given below in the diagram attached, it shows that the Texas horned lizard feeds mainly on ants and grasshopper as a secondary consumer in the food web. As a result of this, the population of ants and grasshoppers would be often put in check and regulated.
However, if a disease suddenly reduces the population of the Texas horned lizard, it means that ants and grasshoppers won't be heavily preyed on anymore, since the population of their major predator has now been reduced.
Therefore, a reduction in the population of Texas horned lizard would result in the increase in the population of ants and grasshoppers.
Answer: Ants and grasshoppers

Which is required for sexual reproduction? 1.mitosis 2.binary fission 3.diploid cell production 4.meiosis
Answer:
4. Meiosis
Explanation:
Mitosis creates cells for growth and repair, not for sexual reproduction. Binary fission is a form of asexual reproduction, not sexual reproduction. Diploid cell production is mitosis (mitosis creates diploid cells, or cells with a full set of chromosomes)
Meiosis is the correct answer. Meiosis creates gametes or sex cells that are necessary for sexual reproduction. Through this cell division process, 4 gametes are produced. The cells that are produces are haploid, which means they only have half of a full set of chromosomes. The cells are haploid because, during fertilization, a sperm (male sex cell) and egg (female sex cell) fuse. The result is a diploid zygote with half of the genetic information from the father and the other half from the mother.
The correct answer is 4. Meiosis.
Answer:
its D. Meiosis

Explanation:
A student observed a dying plant in the corner of their science classroom. They learned the process of Photosynthesis and Cellular Respiration already in class. The students were trying to remember the correct chemical equation for the process. In order for the plant to be successfully creating its own food which chemical equation did the student write correctly?
Answer:
The general chemical equation for photosynthesis is
6CO2 +6 H20 → C6H1206 + 602,
Where CO2 is carbon dioxide, H20 is water, C6H12O6 is glucose, and O2 as oxygen a byproduct.
the process begins with the splitting of water molecules-Photolysis.
2H20 +2 NADP + 8 Photons → NADPH + 2H+2 O. Photons is sunlight that splits the water molecules.
Cellular respiration is the reverse of the process which is the
C6H1206 +6 O2 → 6H20 +6 CO2 +ATPs.
ATPs is the chief product, while C02 is the byproduct.

When the immune system treats otherwise harmless substances, such as pollen, as if they were invaders, a/n ______ can occur.
HIV is a virus that attacks ______ in the body, weakening the immune system.
Polio used to be fairly common and devastating. Thanks to widespread vaccination against polio, the disease is now considered _______, no longer infecting nearly as many people as it once did.
Arthritis is an example of a/n _______, where part of a person’s body is identified as foreign and attacked by the person’s immune system.
Respond to the following based on your reading.
Colonization is largely blamed for bringing smallpox to the Americas. Why was this disease so devastating to Native Americans? Why can we now travel to different parts of the world and avoid contracting analogous diseases?
Answer:
Killing pathogens and then using them to provide the body with active immunity is called IMMUNIZATION . This is often done in young children.
When the immune system treats otherwise harmless substances, such as pollen, as if they were invaders, a/n ALLERGY can occur.
HIV is a virus that attacks WHITE BLOOD CELLS in the body, weakening the immune system.
Polio used to be fairly common and devastating. Thanks to widespread vaccination against polio, the disease is now considered ABSENT, no longer infecting nearly as many people as it once did.
Arthritis is an example of a/n AUTOIMMUNE DISORDER where part of a person’s body is identified as foreign and attacked by the person’s immune system.
Immunization helps involves the injection of dead pathogens into the bloodstream. This helps in the release of antibodies which helps in protecting the body against further attacks in the future.
Allergy happens as a result of the body system treating and attacking harmless substances.
This is because the ships which brought immigrants into the country had someone who had small pox on board which spread and many got infected and killed due to lack of vaccine and treatment.
Immunization helps people to travel without having to worry about diseases.
Answer:
vaccination
allergic reaction
t-cells
eradicated
autoimmune disease
Europeans had been exposed to the virus that causes smallpox for many generations, allowing them to acquire immunity to the virus. Native Americans were not exposed to smallpox or similar viruses before, so they had no immunity to the virus. In modern times, before traveling abroad, a person often receives vaccinations or other medications to avoid contracting the diseases specific to that region of the world.
