The more impressive the tail of a male peacock, the higher its chances of finding a mate. Female peacocks choose mates based on

the color of the feathers and the overall physical prowess of the animal. However, a genetic mutation called leucism can produce a peacock with only white feathers. This mutation causes the inability of pigment to be deposited into their feathers which results in a white appearance. What would you infer to be the fitness of the white peacock? Choose ALL that apply.
A) The females will equally choose the brightly colored and white peacocks as mates.
B) White peacocks are highly prized, thought to symbolize purity, eternity, and unconditional love, making them desirable mates.
C) If females choose the brightest males as partners, the ones without the impressive tails will be less likely to mate and reproduce.
D) White peacocks are highly prized, thought to symbolize purity, eternity, and unconditional love, causing them to be selectively bred for their unique trait.
E) The peacocks with colored tails will be picked over the white peacocks as mates, causing the peacocks with the white mutation to die out of the population over time

Explain how, the removal of thermal energy (heat) from matter affects its particles.
WINSTONCH [101]

Answer:

When a substance is heated, it gains thermal energy. Therefore, its particles move faster and its temperature rises. When a substance is cooled, it loses thermal energy, which causes its particles to move more slowly and its temperature to drop.

Sodium Chloride is an ionic compound. Its molar mass is 58.44g. One formula unit of NaCl consists of one____, whose chemical sym
saul85 [17]

Answer: One formula unit of NaCl consists of one cation, whose chemical symbol is Na^+ and one anion whose chemical symbol is Cl^-

Explanation:

For formation of a neutral ionic compound, the charges on cation and anion must be balanced. The cation is formed by loss of electrons by metals and anions are formed by gain of electrons by non metals.  

The cation is formed by the metal sodium which forms  Na^+ and the anion is formed by non metal chlorine which forms Cl^-.

For a formula unit of sodium chloride,  the charges have to be balanced , thus the valencies of ions are exchanged and the neutral compound result. Thus

Na^+ and  Cl^- combine to form neutral NaCl

Enter the symbol of a sodium ion, Na+, followed by the formula of a sulfate ion, SO42−. Separate the ions with a comma only—spac
gladu [14]

Na⁺,SO₄²⁻ is the answer

<h3>Further explanation </h3>

An ion is an atom or molecule that has a net electrical charge. There are many ions, one of them are sodium ion and sulfate ion.

SO₄²⁻ or Sulfate is a naturally occurring polyatomic ion that consist of a central sulfur atom surrounded by four oxygen atoms with occured widely in everyday life. Sodium ions are important for regulation of blood and body fluids, transmission of nerve impulses, heart activity, and certain metabolic functions.

Whereas Na⁺ or Sodium is a chemical element with the symbol Na and atomic number 11. It is a soft, silvery-white, highly reactive metal. Sulfate ion is a very weak base. Therefore sulfate ion undergoes negligible hydrolysis in aqueous solution.

Enter the symbol of a sodium ion, Na⁺, followed by the formula of a sulfate ion, SO₄²⁻. Separate the ions with a comma only—spaces are not allowed. Express your answers as ions separated by a comma. Therefore the answer is: Na⁺,SO₄²⁻

Hope it helps!
