Note about the question:

Among the (observed-expected)² list, there is one value missing. This value corresponds to round yellow gray plants, and equals 0.002. This number was included in the explanation of the problem.

Answer:

The chi-square value is X² = 2.6813.

Explanation:

Available information:

Observed individuals numbers:

The expected numbers

The (observed-expected) ² numbers

To get the chi-square value, we just need to replace the terms in the following equation.

                       Chi square= ∑ ((O-E)²/E)

Where,  

X² = ∑ ((O-E)²/E)  

X² = (0.002/269.58) + (65.61/89.86) + (15.2/89.86) + (3.61/89.86) + (8.41/29.95) + (16.81/29.95) + (0.01/29.95) + (9/9.98)

X² = 0.0000074 + 0.73 + 0.17 + 0.04 + 0.28 + 0.561 + 0.0003 + 0.9

X² = 2.6813

To get the chi-square value, we simply want to update the phrases withinside the following equation.

[tex]Chi square = Sigma((O - E) ^ 2 / E)[/tex]

Where,

[tex]Σ[/tex] is the sum of the phrases

O refers back to the Observed variety of individual

E refers back to the Expected numbers of people

[tex]X ^ 2 = Sigma((O - E) ^ 2 / E)[/tex]

[tex]X^ 2 =(0.002/269.58)+(65.61/89.86)+ Chi quare = Sigma((O - E) ^ 2 / E)[/tex]

Where,

Σ is the sum of the phrases

O refers back to the Observed variety of individual

E refers back to the Expected numbers of people

[tex]X ^ 2 = Sigma((O - E) ^ 2 / E)[/tex]

[tex]X^ 2 =(0.002 / 9.58)+(65.61/ 89.86) + (15.2/89.86)+(3.61/89.86)+(8.41/29.95)+ (16.81/29.95) + (0.01/29.95) + (9/9.98)[/tex]

[tex]X^ 2 =0.0000074+0.73+0.17+0.04+ 0.28 + 0.561 + 0.0003 + 0.9[/tex]

[tex]X ^ 2 = 2.6813[/tex]

Pearson's chi-square test is utilized to inspect the job of chance in creating deviations among noticed and anticipated values. The test relies upon extraneous speculation since it requires hypothetical anticipated that values should be determined.

Hence it clearly calculates the value of chi-square.

Answer:

a. 4 R¹R²

b. 4 Pink flowers

c. 1 Red, 2 pink and 1 white phenotypes

d. 1R¹R¹ : 2R¹R² : 1R²R²

Explanation:

This question involves a single gene coding for flower color in petunia plants. However, the allele for red flower color (R¹) is incompletely dominant over the allele for white flower color (R²), hence, a pink intermediate phenotype (R¹R²) is formed.

According to these questions;

A. If a white-flowered plant (R²R²) is crossed with a red-flowered plant (R¹R¹), all of the F1 generation will have a genotype of R¹R² (see attached image for punnet square).

B. The F1 generation, which possess a genotype: R¹R² will express the pink flower phenotype because neither of the two alleles are truly dominant over the other i.e incomplete dominance.

C. If two of the F1 offspring were crossed i.e. R¹R² × R¹R², each parent will produce R¹ and R² gametes. Using these gametes in a punnet square (see attached image), the following phenotypes will be produced in the F2 generation: Red, pink and white phenotypes

D. The F2 generation will possess a genotypic ratio of 1R¹R¹ : 2R¹R² : 1R²R².

Answer:

Grasslands and herbivores have a mutually beneficial symbiotic relationship. If larger herbivores such as Kangaroos and Elephants are removed from them, they may become extant.

Explanation:

Herbivores are always hungry and they are always looking for ways to replenish lost energy. Between tree shoots and grass, they often go for the former because they are tender, easier to reach, and less difficult to masticate than the young tree shrubs.

When baby trees become bigger, their shade prevents adequate sunlight from reaching the grass, then gradually they become scanty or subdued for as long as the shade remains.

When large herbivores are removed or leave a grassland, trees have the ability to flourish. Then the results indicated above happens.

Gene flow is an important mechanism for transferring genetic diversity among populations. ... Gene flow is expected to be lower in species that have low dispersal or mobility, that occur in fragmented habitats, where there are long distances between populations, and when there are small population sizes.

Because it is important for transferring genetic diversity among populations.  Even low levels of gene flow can have a large impact, counteracting the other evolutionary force.

Answer: warm front

Explanation: When a warm air mass meets a cold air mass, the warm air rises since it is lighter. At high altitude it cools, and the water vapor it contains condenses. This type of front is called a warm front. It generates nimbostratus clouds, which can result in moderate rain.

B is true

i took the test

Oil is a renewable energy resource. It is processed to make jet fuel. Thus, the correct option is B.

Renewable energy is the energy which is derived from natural sources which are replenished at a higher rate than they are being consumed. Sunlight and wind are the two such sources of energy which are constantly being replenished from the planet. Renewable energy sources are present in plentiful amounts and are found all around us.

Jet fuels are the energy fuels which are typically made by the blending and refining of various crude oils such as petroleum distillation products including naphtha, gasoline, or kerosene in order to meet the specific military or commercial specifications required.

Therefore, the correct option is B.
