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:
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.
Answer:
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.

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.

Which type of selection leads to increased phenotypic and genetic variation? directional selection disruptive selection stabilizing selection species selection
Answer:
diruptive selection/ diversifying selection
Explanation:
disruptive selection often leads to more variations in species
The circumstance that concludes whether the organism will be able to accommodate and endure in the changed conditions is called selection.
The correct answer is:
Option B. Disruptive selection.
This can be explained by:
Disruptive or diversifying adaptation occurs when there is a change in population genetics in which the traits are valued over intermediates.This type of assortment supports either the dominant or the recessive trait but do not favour intermediates.For example, in selection between tall, short or intermediate organisms the tall and short will be selected over the medium heightened organism.Therefore, disruptive selection will lead to increased phenotypic and genetic variation.

why is nectar important for insects?
Answer:
Nectar is important for insects because.. Nectar is an ecologically important item, the sugar source for honey. It is also useful in agriculture and horticulture because the adult stages of some predatory insects feed on nectar. For example, the social wasp species Apoica flavissima relies on nectar as a primary food source. In turn, these wasps then hunt agricultural pest insects as food for their young.

in the term 2pq of the Hardy-Weinberg equation. Why is the multiplication by two necessary?
PLEASE HELP ME!!!!!
A-The term is multiplied by two because the effect of both the alleles is taken into account.
B-There are two ways that a heterozygous individual can arise: either by receiving a recessive allele from the egg and a dominant allele from the sperm, or by receiving a dominant allele from the egg and a recessive allele from the sperm
C-The frequency of the dominant allele is doubled because of its stronger effect on the phenotype.
D-The term is multiplied by tvo to account for doubling of the population in each generation.
Answer:
The correct answer is : option B.
Explanation:
Hardy–Weinberg equilibrium is a mathematical model that states that genotype percentage or frequency in a population and allele in a population remains stable or constant to generations if there are no evolutionary influences present.
Hardy Weinberg equation is :
P²+2pq+q² = 1
Here, p² represents the frequency of genotypes dominant homozygotes (AA) in a population in equilibrium. The term 2pq represents the frequency of heterozygotes (Aa) as there are two ways of developing heterozygous individuals either dominant from the egg and recessive from sperm or vice versa. and the term q² represents the frequency of recessive homozygotes (aa).
Thus, the correct answer is : option B.
There are two ways that a heterozygous individual can arise: either by receiving a recessive allele from the egg and a dominant allele from the sperm, or by receiving a dominant allele from the egg and a recessive allele from the sperm, the frequency of the heterozygous allele is multiplied by 2 (option B).
The Hardy–Weinberg equation is an equation which expresses the principle of Hardy-Weinberg equilibrium. The Hardy-Weinberg equilibrium states that in the absence of external evolutionary factors which disturbs equilibrium, the amount of genetic variation in a population will remain constant from one generation to the next.
The Hardy Weinberg equation is given as: p² + 2pq + q² = 1
In the equation above,
p² represents the frequency of dominant h0m0zygotes (AA)q²represents the frequency of recessive h0m0zygotes (aa),2pq represents the frequency of heterozygotes (Aa),p represents the allele frequency of the allele A and q represents the allele frequency of the allele a.The sum of all the three frequencies equal to 1 representing all the possible allele combinations.Since there are two ways that a heterozygous individual can arise: either by receiving a recessive allele from the egg and a dominant allele from the sperm, or by receiving a dominant allele from the egg and a recessive allele from the sperm, the frequency of the heterozygous allele is multiplied by 2.

When multiple glaciers start their downward flow from a single point, they create a .
Answer:
They create a Mountain Peak
When multiple glaciers start their downward flow from a single point, they create a Mountain peak. So, the correct option is B.
What are Glaciers?A glacier is a sizable, slowly moving mass of ice that develops over a considerable amount of time as a result of the buildup of snow and ice. In areas where the average temperature is below freezing and there is enough snowfall to offset the melting that takes place during the summer, glaciers can be discovered. They can occur at lower elevations in some places, although they are mainly found at high altitudes or in the polar regions.
When several glaciers begin to flow downward, they build something resembling a pyramid. The mountain peak is created as a result of the glacier's movement from a single location. Due to the simultaneous movement of several glaciers to the ground, a pointed structure has recently created.
Therefore, the correct option is B.

Felipe believes that whenever the Moon is in the position that is shown from above (top view) in Diagram A, the Moon always looks completely bright in the view from Earth, as shown in Diagram B. Is Felipe correct? If he is correct, explain why the Moon always looks bright from Earth in that position, and explain how he should show light on the Moon in Diagram A. If he is incorrect, explain how else the Moon can look when it is in that position.
Answer: Felipe is wrong.
Explanation:
In diagram A, we can see that the light comes from the left, it first impacts on the Earth, and then we have the Moon.
Now, you can model this situation with a flashlight (the Sun) a basketball (the Earth) and a tennis ball (the Moon)
When you point with the flashlight at the basketball, the basketball will look bright, but it will cast a shadow behind it. This shadow will cover the tennis ball, and almost no light will reach the tennis ball, so it will not look bright.
This phenomenon is called a lunar eclipse, and this happens when the Earth is in between the Sun and the Moon. When this happens, we see the moon a bit darker and more reddish.
Felipe is incorrect, as it will not be possible to see the moon if it is in the position shown in the diagram.
We can come to this answer because:
It is only possible to see the moon when it is reflecting sunlight.In this case, no other type of celestial body must be in front of the moon, blocking the sunlight.As we can see in the question above, sunlight is being emitted from left to right.Although the moon is in the right direction to reflect this light, the earth is in front of the moon.Therefore, sunlight will not shine on the moon, because the earth will block it and cast a shadow over the moon.Therefore, it will not be possible to see the moon, as Felipe said.

Mammals that live in the Arctic Ocean have a large amount of blubber, which is a fatty tissue just beneath the skin.
Which statement best relates why these animals have so much blubber?
O Lipids in blubber insulate the animals from cold water.
O Proteins in blubber help the animals move to stay warm.
O Carbohydrates in blubber provide all the energy that the animals need to stay warm.
O Nucleic acids help build the lipids in blubber, which keep animals warm by regulating cell activities.
Answer:
Lipids in blubber insulate the animals from cold water.
Explanation:
Lipids are fatty tissue, or fats in the cells. Blubber is fat. The fat helps insulate animals from cold water, especially in the Arctic known for being freezing. Fats can help maintain and keep body heat, hence why skinnier people are colder. Without lipids, they would most likely freeze.
