Answer: The correct answer for the fill in the blank is Fat because they store twice as much energy per gram.

There are three sources of energy in animals that is proteins, fats, and carbohydrates. The most concentrated form of metabolic energy found in nature is fat. One gram of fat provides approximately 9 calories, whereas carbohydrates or proteins provide only 4 calories per gram.

Thus, most of the excess energy is stored as fats in animals.

They store it as adipose tissue because it also provide heat, insulation, and protection.

Predict the dominant type of bonding by considering electronegativity.

Vlad1618 [11]

If the atoms that are bonding have identical electronegativities, then it's a completely nonpolar covalent bond. This doesn't happen in the real world unless the two atoms are of the same element. In a practical sense, any two elements with an electronegativity difference less than 0.3 is considered to be nonpolar covalent.
As the difference between the atoms increases, the covalent bond becomes increasingly polar. At a polarity difference of 1.7 (this changes depending on who you ask) we consider it no longer to be a covalent bond and to be the electrostatic interactions characteristic in an ionic compound.
Just so you know, you shouldn't take these values as exact. ALL interactions between adjacent atoms involve some sharing of electrons, no matter how big the difference in electronegativity. Sure, you wouldn't expect much sharing in KF, but there's a little sharing of electrons anyway. There's certainly no big cutoff that happens at a difference of 1.7 Pauling Electronegativity units.

Two independently segregating genes determine kernel color in wheat. Red color results from at least one dominant allele in both

Lera25 [3.4K]

Answer:

a) The expected phenotype of the F1 plants is 100% RrBb, red kernels.

b) The expected phenotypic classes in the F2 are: 9:3:3:1

9/16 R-B-, 3/16 rrB-, 3/16 R-bb, 1/16 rrbb

Proportions 9:6:1.

9/16 Red kernel (R-B-), 6/16 Brown kernel (rrB- + R-bb), 1/16 White kernel (rrbb)

Explanation:

Available data:

red kernel: R-B-

brown kernel: R-bb or rrB-

white kernel: rrbb

1º Cross) RRBB x rrbb

F1) 100% RrBb (red kernels)

2ºCross) RrBb x RrBb

Gametes) RB RB

Rb Rb

rB rB

rb rb

Punnet Square) RB Rb rB rb

RB RRBB RRBb RrBB RrBb

Rb RRBb RRbb RrBB Rrbb

rB RrBB RrBb rrBB rrBb

rb RrBb Rrbb rrBb rrbb

F2) Phenotypic classes:

9/16 R-B-

 3/16 rrB-

 3/16 R-bb

 1/16 rrbb

Phenotypic proportions:

9/16 Red kernel (R-B-)

6/16 Brown kernel (rrB- + R-bb)

1/16 White kernel (rrbb)

Explain why the Milky Way galaxy appears as a narrow band of light in the night sky

Gnom [1K]

It is called the Milky Way because it appears as a milky band of light in the sky when you see it in a really dark area. Just as the Earth goes around the Sun, the Sun goes around the center of the Milky Way.
