Answer:

1. Allele for shortness (t)

2. Allele for tallness (T)

Explanation:

Gregor Mendel performed numerous experiments using pea plants (Pisium sativum). He tested the height traits of pea plants by crossing tall pea plants (TT) and short pea plants (tt) to obtain offsprings that were all tall (Tt) in the first filial generation (F1).

This is possible because the allele for tallness is DOMINANT while the allele for shortness is RECESSIVE. This means that tallness allele (T) will mask the phenotypic expression of shortness allele (t) when in an heterozygous state (Tt) as in the F1 generation.

The presence of rust in the water of Westfield is the reason for the change in colour.

The water of Westfield has reddish-brown substance. This reddish brown substance in the water is the rust which formed due to the chemical reaction between the iron pipes and the fertilizer substance present in the water.

Due to this reaction, the colour of Westfield's water is different from normal type of water so we can conclude that the presence of rust in the water of Westfield is the reason for the change in colour.

Answer:

The role of consumers in an ecosystem is to obtain energy by feeding on other organisms and sometimes transfer energy to other consumers. Changes that affect consumers can impact other organisms within the ecosystem.

Explanation:

Hope this helped Mark BRAINLIEST!!!!

Consumers are organisms that obtain energy by eating other organisms. Consumers may consume either producers or other consumers. Consumers include animals.

A food chain is a network of links in a food web that begins with producer organisms and ends with an apex predator, detritivore, or decomposer species.

A food chain also demonstrates how organisms are related to one another through the food they consume. Each trophic level is represented by a different level of a food chain.

Producers can produce their own food and energy, but consumers are not the same. Consumers are living things that must hunt, gather, and eat their food.

Thus, Consumers must eat in order to gain energy, or they will perish. Omnivores, carnivores, herbivores, and decomposers are the four types of consumers.

Explanation:

Answer:

K = [HI]² / [H₂] [I₂]

Explanation:

To write the expression of equilibrium constant, K, it is important that we know how to obtain the equilibrium constant.

The equilibrium constant, K for a given reaction is simply defined as the ratio of the concentration of the products raised to their coefficient to the concentration of the reactants raised to their coefficient. Thus, the equilibrium constant is written as follow:

K = [Product] / [Reactant]

Now, we shall determine the equilibrium constant for the reaction given in the question above. This can be obtained as illustrated below:

H₂(g) + I₂(g) —> 2HI (g)

K = [HI]² / [H₂] [I₂]

Answer:Base A is the weakest conductor electricity

Explanation:

Dissociation is a factor that affects electrical conductivity. The greater the percentage of dissociation for bases the stronger the conductivity of electricity.

Given that

Base A dissociates 25% in water

Base B dissociates 50%.

Base C dissociates 75%

We can conclude that  Base A is the weakest conductor oelectricity since it has the lowest percentage of dissociation.

Explanation:

when Magnesium is reacted with Aluminum oxide, Aluminum being a less reactive metal than magnesium, is replaced by magnesium

Al2O3 + 3Mg - 3MgO + 2Al

hence reaction takes place

Answer:

0.075 moles of iron oxide would be produced by complete reaction of 0.15  moles of iron.

Explanation:

The balanced reaction is:

4 Fe + 3 O₂ → 2 Fe₂O₃

By reaction stoichiometry (that is, the relationship between the amount of reagents and products in a chemical reaction), the following amounts of moles of each compound participate in the reaction:

You can apply the following rule of three: if by stoichiometry 4 moles of Fe produce 2 moles of Fe₂O₃, 0.15 moles of Fe produce how many moles of Fe₂O₃?

[tex]moles of Fe_{2} O_{3} =\frac{0.15 moles of Fe*2 moles of Fe_{2} O_{3} }{4 moles of Fe}[/tex]

moles of Fe₂O₃= 0.075

0.075 moles of iron oxide would be produced by complete reaction of 0.15  moles of iron.

Answer:

567 calories.

Explanation:

There 567 calories in 100 grams of peanut. In 100 grams of peanut, 49 gram is the fat, 26 grams of protein, 16 grams of carbohydrates, Sodium is 18 mg, Potassium is 705 mg. Calcium is present in peanut about 9%, Iron is 25% , Vitamin B-6 is 15%  and Magnesium is 42% of their total weight. Oil content is high in the Peanut so this is the reason for high calories in peanut. It is a good source of proteins and potassium.

Answer:

d. Two moles of carbon dioxide were produced from this reaction

Explanation:

The given chemical reaction can be written as follows;

2C₂H₂ + 5O₂ → 4CO₂ + 2H₂O

From the above chemical reaction, we have;

Two moles of C₂H₂ reacts with five moles of O₂ to produce four moles of CO₂ and two moles of H₂O

We have;

One mole of C₂H₂ will react with two and half moles of O₂ to produce two moles of CO₂ and one mole of H₂O

Therefore, in the above reaction, when one mole of C₂H₂ is used, two moles of CO₂ will be produced.

Answer:

22.2 g of MgF₂

Explanation:

We star from the reaction:

NaF → sodium fluoride

Mg → Magnesium

2NaF  +  Mg →  MgF₂  +  2Na

2 moles of sodium fluoride react to 1 mol of Mg in order to produce 1 mol of magnesium fluoride and 2 moles of sodium.

We convert mass of the reactant to moles:

30 g . 1mol / 41.98 g = 0.715 mol

We assume that Mg is in excess

As ratio is 2:1, if we have 0.715 moles of NaF we may produce the half of moles, of MgF₂

0.715 mol /2 = 0.357 moles of MgF₂

We convert moles to mass: 0.357 mol . 62.30g /mol = 22.2 g

The relationship between the rate of diffusion and the molar mass is given by Graham's law.  A gas diffusing 1/6 times faster than hydrogen will have a molar mass of 72.58 g/mol. Thus, option d is correct.

Graham's law states the inverse relationship between the rate of diffusion and the square root of the molar mass of the gas. It is given as,

Rate = 1 ÷ √M

The molar mass of the gas that diffuses 1/6 times faster than hydrogen is calculated as,

R₁ ÷ R₂ = √ (M₂ ÷ M₁)

Here,

The molar mass of hydrogen = M₁

The molar mass of unknown gas = M₂

Rate of diffusion of hydrogen gas = R₁

Rate of diffusion of unknown gas = R₂ = 1 / 6 R₁

Substituting values:

R₁ ÷ 1/6 R₁ = √M₂ ÷ 2

6 × 1.414

= 8.485

= 84.85 g/mol ≈ 72.58 g/mol

Therefore, option d. 72.58 g/mol is the molar mass of unkown gas.
