The genotype and phenotype ratio for the first cross will be 100% Rr and 100% round seeded while that of the second cross will be 1RR:1Rr and 50/50 round/wrinkle seeded offspring respectively.
Genotype and phenotype ratioFor the first cross:
RR x rr
Rr Rr Rr Rr
Genotype ratio: 100% Rr
Phenotype ratio - 100% round seeded
For the second cross:

The electrons that are in the outermost electron shell, also known as the ____________ , have ____________ energy than those in the inner electron shells.
Answers
To see the number of atoms of an element in a given molecule we need to multiply stoichiometry to the number that is written on the foot of the element that is stoichiometry. The outermost electrons are called valence electrons and its energy is higher than the core electrons.
What is atom?Atom is the smallest particle of any element, molecule or compound. Atom can not be further divided. Atoms contains nucleus in its center and electron that revolve around the atom in fixed orbit.
In the nucleus, proton and neutron are present. Electron has -1 charge while proton has +1 charge. Neutron is neutral that is it has no charge. So overall the charge of nucleus is due to only proton, not by neutron.
The electrons that are in the outermost electron shell, also known as the valence electrons, have higher energy than those in the inner electron shells.
Therefore, the outermost electrons are called valence electrons and its energy is higher than the core electrons.

Answers
The position is the strength of the magnetic field strongest is is the place where the magnetic field leaves, being point A.
What generates a magnetic field?When an electrically charged particle moves, it creates a magnetic field. According to the laws of electromagnetism, this magnetic field originates from the variation of the electric field strength.
In the region of the poles we see that the lines of magnetic induction are closer to each other, therefore, we consider that close to the poles the magnetic field is more intense.

What is molecule?
A molecule is just a collection of more than two atoms bound together by chemical bonds; depending on the context, the phrase doesn't have to include ions that meet this requirement.
What is homogeneous mixture?Solids, liquids, as well as gases, can all be homogeneous mixtures. Through, they have almost the same look and chemical makeup.

What is an ionic compound?Ionic compounds are neutral compounds made up of positively charged ions called cations and negatively charged ions called anions.
Barium is a metal element and Nitrogen is a non-metal element, so they form an ionic compound. To make the formula of an ionic compound, first, we need to see the valence of the atoms, that is, how many electrons it can donate or it has to gain to have 8 electrons in the valence layer (octet rule).
Barium is in family 2, so it has two electrons in its valence layer, so it must donate these two electrons; Nitrogen is in family 15, so it has 5 electrons ins its valence layer and must gain 3 electrons.
Writing the ions they must form:
[tex]Ba^{+2}N^{-3}[/tex]
First came the cation (positive charge), then the anion (negative charge), and the charges must change between them, without the signal, and will inform how many atoms are necessary for which element:

What is the ideal gas equation?The ideal gas equation shows the relationship between number of moles, temperature, volume and pressure.
Now;

Based on observation of polar and non-polar molecules, polar molecules would attract each other more strongly.
What are polar and non-polar molecules?Polar molecules are those molecules that can ionize or dissociate into their respective positive and negative ions when in an aqueous solution.
Nonpolar molecules, on the other hand, are not ionic i.e. not dissociating into ions when dissolved in water.
Polar molecules like water (H2O) contains an uneven distribution of cations (+) and anions (-), hence, would be more attracted to one another than nonpolar molecules that have an even distribution of ions.
