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.

Answers

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.

The nucleus in both plant and animal cells “specializes” the cells so they can do different things- for example, a liver cell or a muscle cell do different things.  Thinking about plants or trees, what special functions might different cells in a tree or plant do?

Answers

Plant cells are the basic unit of life in organisms of the kingdom Plantae. They are eukaryotic cells, which have a true nucleus along with specialized structures called organelles that carry out different functions. Plant cells have special organelles called chloroplasts, which create sugars via photosynthesis. They also have a cell wall that provides structural support

Seismologists are professionals in geology that compare earthquakes by measuring their elastic rebound (option D).

What is an elastic rebound?

The elastic-rebound can be defined as the amount of energy (or energy transfer) that can be generated by earthquakes.

Seismologists are professionals in geology that compare earthquakes by using this type of measurement.

In conclusion, seismologists are professionals in geology that compare earthquakes by measuring their elastic rebound (option D).

When multiple glaciers start their downward flow from a single point, they create a .

Answers

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.

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.

Answers

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,

represents the frequency of dominant h0m0zygotes (AA)represents 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.

Which type of selection leads to increased phenotypic and genetic variation? directional selection disruptive selection stabilizing selection species selection

Answers

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.
