Explanation:

Yo,

In Geranium plant life red vegetation is given by using the allele R this is dominant (so RR or Rr ) genotype will produce crimson plant life.

If we communicate approximately the connected punnet square which i took from the workout e book, you could see that there was a cross made among vegetation with heterozygous genotype for red flora.

P1: Rr X Rr

Gametes: R: r : R : r

F1: RR: Rr: Rr: rr

so there is three: 1 in F1 offspring for red to white plant life.

Now the query is set f2 technology, while we cross F1 generation suppose we do a move of Rr and rr from F1 generations allow us to see what takes place.

F1: Rr: rr

Gametes: R: r: r: R

F2 : Rr : rr: Rr: rr

Rr: purple flowers

rr: White flora:

So the ratio in F2 era might be 2 crimson : 2 white. Please see connected punnet squares (first one for query) and the second of F1 move for better know-how.

I'm hoping that this will benefit you, so from my assumption and study it'd be 2 crimson : 2 white, if this is indeed the one i'm thinking of since nothing else was provided, if not please correct me.

Answer: 2 red : 2 white

Answer:

Even though the two substances possess many similarities, they have some unique properties. In turn, since they have the same properties, if they were the same substance, it would make matters worse, if the same chemical was in two different places, there would not be a difference between them since they are the same, just as it is with are two different chemicals would have differing properties since they are two properties would vary from one another since they are 2 totally different things!

Explanation:

First, the amount of sunlight received at a given latitude is important. At the equator, the sun is high in the sky and thus very intense. As you move away from the equator, the sun does not reach as high of an angle in the sky, and is less intense. Another important effect near the poles is that during the summer, the sun is up all the time, which boosts the total amount of sunlight received in a day, while in contrast, during the winter, no sunlight is received at all.

There is another, more subtle effect that has to do with latitude. Nature likes to have the temperature be the same everywhere, much like ice cream melts at room temperature or a hot cup of coffee cools to room temperature. The equator is getting blasted with intense sunlight, while the poles are getting a lot less. Nature tries to resolve this imbalance and make the atmosphere the same temperature everywhere. The most efficient way to transfer heat towards the poles depends on latitude and the rotation of the Earth in a complex way. In the tropics (within 30 degrees latitude of the equator), the average daily temperature is mostly constant. Whether you move from north to south, say fro the equator to Mexico, the temperature is mostly the same. Compare that to the midlatitudes (30–60 degrees latitude), where the temperature changes rapidly as you move north or south to the poles. For example, the temperature in Texas is a lot hotter than the temperature in North Dakota.

Another factor is the composition of the surface. Different substances absorb, store, and re-emit heat with different levels of efficiency. The ocean is a major factor, which can either warm or cool the adjacent land. Other surface materials like rock, sand, vegetation, and ice also regulate temperature

The elevations of the surface, specifically mountains effect the climate. Usually, the taller the mountain, the colder the temperature is at the top. Mountains also cause air to flow in certain ways around them, which leads to wet areas on the upwind side and dry areas on the downwind side.

The IUPAC name for a binary covalent compound will lack roman numerals.

Binary covalent compound comprises of two elements which forms a

compound through the sharing of electrons.

The sharing of electrons is referred to as covalent bonding and naming such

compounds require prefixes such as mono-, di- , tri- etc.

The standard method of naming these compounds should be with the

prefixes and not with the roman numerals.

An example is carbon(IV)oxide which is wrong in  IUPAC naming.

Explanation:

Labor unions arose in the nineteenth century as increasing numbers of Americans took jobs in factories, mines, and mills in the growing industrial economy.

The Knights of Labor, founded in 1869, was the first major labor organization in the United States. The Knights organized unskilled and skilled workers, campaigned for an eight hour workday, and aspired to form a cooperative society in which laborers owned the industries in which they worked.

The Knights’ membership collapsed following the 1886 Haymarket Square riot in Chicago. By 1886 the American Federation of Labor (AFL), an alliance of skilled workers’ trade unions, was growing.

Explanation:

1. 1 mol Mg = 24.31 g = 6.02 *10^23 atoms

     calculate the number of atomsin 80.45g Mg

         Numberof atoms = 6.02*10^23 Mg atoms / 24.31 g * 80.45 g

                                    = 1.99*10^24 atoms

2.1 mol C-12 = 12.01g = 6.02 * 10^23 atoms

    calculate the mass using

                                       = 12.01 g C / 6.02*10^23 atoms * 100 atoms

                                       = 1.99 * 10^-21 g

Answer:

1.9926 * 10 ^24 

Explanation:

Molar Mass - Use Periodic table!

M ( Mg ) = 24.31 g / mole

n = 80.45 g : 24.31 g/mole = 3.31 moles

N a ( Avogadro`s constant ) = 6.02 * 10 ^23

N = Na * n = 6.02 * 10 ^24 * 3.31 = 19.926 * 10 ^23

Explanation:

Protons are positively charged and electrons are negatively charged so if it is a neutrally charged atom (which most are) the protons and electrons will be equal.

The mass of Fe produced from the reaction is 0.938 g.

We'll begin by calculating the mass of Fe2O3 that reacted and the mass of Fe produced from the balanced equation.

3Zn + Fe₂O₃ —> 2Fe + 3ZnO

Molar mass of Fe₂O₃ = (56×2) + (16×3) = 160 g/mol

Mass of Fe₂O₃ from the balanced equation = 1 × 160 = 160 g

Molar mass of Fe = 56 g/mol

Mass of Fe from the balanced equation = 2 × 56 = 112 g

From the balanced equation above,

160 g of Fe₂O₃ reacted to produce 112 g of Fe.

Finally, we shall determine the mass of the Fe produced by 1.34 g of Fe₂O₃

From the balanced equation above,

160 g of Fe₂O₃ reacted to produce 112 g of Fe

Therefore,

1.34 g of Fe₂O₃ will react to produce = (1.34 × 112)/160 = 0.938 g of Fe

Thus, 0.938 g of Fe was produced from the reaction.

Explanation:

The compound with the presence of higher inter-molecular forces has been Acetic acid. Thus, option A is correct.

The boiling point has been the temperature, at which the liquid has been started to convert to steam. The boiling has been mediated with the application of the energy to the substance for the breaking of the inter-molecular forces.

The higher the inter-molecular forces in the compound, the higher will be the boiling point of the compound. The higher concentration has also resulted in a higher boiling point.

In the following compounds, acetic acid has the highest boiling point of 118 degrees Celsius. Thus, it has been constituted of the higher inter-molecular forces. Hence, option A is correct.
