Answer: Option D.

Explanation:

An ionic bond is defined as a chemical bond forms when two oppositely charged ions undergo electrostatic attraction. Ionic bonds always formed between a metal (cation), and a nonmetal (an anion).

Ionic bonds are formed when a cation (metal) donates an electron to anion (nonmetal). for example formation of Sodium Fluoride (NaF), sodium (cation) with atomic number eleven is having one valence electron in its outer orbit and fluoride (anion) with atomic number nine require one atom to complete its orbit, so the sodium atoms transfer one electrons to fluoride and leads to the formation of an ionic compound.

Hence, the correct option is D.

Marta_Voda [28]

Answer:

The phenotype of the rabbit is the absence of fur colour and the genotype is the alleles rr.

Explanation:

The genotype can be described as the genes which are present in an organism. Genes are made up of alleles. As the rabbit in the question carries the alleles, rr, hence it is the genotype of the white albino rabbit.

The phenotype can be described as the physical appearance that results from the particular genes present in an organism. As the white albino rabbit carries the alleles,rr, due to which it doesn't have fur, hence no fur is the phenotype of it.
