Answer[tex]__________ is a set of _____ or combination of __________ alleles responsible for an _________ of a trait.[/tex]:
Explanation:
The bonds are formed by the valence electron of the atom. The covalent bonds show poor thermal conductivity and are hard and brittle substances. Thus, options 1. c and e, 2. b and f, 3. a and d are correct.
What are chemical bonds?Chemical bonds are the linkages formed between the atoms of the same or different element by transfer, sharing, and moving electrons of the valence shell of the orbital.
The covalent bonds are formed by sharing the valence electron with the atoms that look hard and brittle and are poor thermal conductors. Thus, options c and e are correct.
The metallic bonds, on the other hand, are formed by the free movement of the electrons in the structures that are ductile and are represented by the electron sea model. Thus, options b and f are correct.
Lastly, the ionic bonds are created by the transfer of the valence electron from one to another atom. They form crystalline structures and molecular compounds with cations and anions in them. Thus, options a and d are correct.
