The number of arrangements of 5 distinct books is 5! = 120.

The number of ways to arrange 5 different colored balls is 5! = 120.

The number of arrangements of 6 distinct balls is 6! = 720.

The number of arrangements of 6 people is 6! = 720.

Choose 3 people from 7: C(7, 3) = 35. The remaining 4 can be divided into 2 groups in 2 ways. Total = 35 * 2 = 70.

Precision refers to the consistency of repeated measurements, regardless of their accuracy.

In Mendel's experiments, yellow seed color was observed to be dominant over green seed color.

Stems, particularly in the form of runners or tubers, are primarily responsible for asexual reproduction in many plants.

Flowers are the reproductive structures in plants that facilitate sexual reproduction.

Isotopes are defined as atoms that have the same number of protons but different numbers of neutrons.

The coefficient of x^0 is given by 4C4 * (2x)^0 * (3)^4 = 1 * 81 = 81.

The coefficient of x^2 is C(6,2) * (2)^2 * (-5)^4 = 15 * 4 * 625 = -37500.

The coefficient of x^3 is C(6,3)(2)^3(-5)^3 = 20 * 8 * -125 = -20000.

The coefficient of x^2 is C(4,2)(3)^2(-4)^2 = 6 * 9 * 16 = -864.

The coefficient of x^3 is C(5,3) * (-1)^2 = 10.

In elastic collisions, both kinetic energy and momentum are conserved, which is a key assumption in the kinetic theory of gases.

The Langmuir isotherm assumes that adsorption occurs at all pressures, not just high pressures.

Zinc (Zn) is oxidized to Zn2+, so its oxidation state is +2.

Iron (Fe) is oxidized as it loses electrons to form FeCl3.

Fe2O3 is reduced to Fe, as it gains electrons during the reaction.

In this reaction, Fe²⁺ is being oxidized to Fe³⁺ as it loses electrons.

Magnesium is oxidized as it loses electrons and its oxidation state increases from 0 to +2.

N2 is reduced to NH3 as it gains electrons.

Iron (Fe) is oxidized as it loses electrons to form Fe2O3.

Copper (Cu) is reduced as it gains electrons from zinc.

Zinc (Zn) is oxidized as it loses electrons to form Zn²⁺.

Cu is oxidized to Cu2+ as it loses electrons in the reaction.

Zn is oxidized to Zn2+ as it loses electrons.

In C2O4^2-, the oxidation state of carbon is +3.

Frogs typically exhibit external fertilization, where eggs and sperm are released into the water.
