Answer:

C. 11 protons, 11 electrons, 12 neutrons

Explanation:

Sodium is an alkali metal whose symbol is Na and atomic number 11. It is highly reactive metal as it is ready to donate a single electron which is present in its outer shell. In each sodium (Na) atom there is 11 protons and 12 neutrons as its atomic mass is 23 (11+12) and number of electrons will be 11 in a neutal sodium atom.

Answer:

Genotype of the offspring: 4 CC is equal ratio.  Phenotype will be 4 yellow cocoons. (CC)

Explanation:

The inheritance of cocoon color in silkworm is a classic illustration of mono-hybrid cross. Mono-hybrid because the color of cocoon is determined by single gene. The yellow color of cocoon is dominant and the homozygous dominant allele is represented as CC. While the white color of cocoon is represented as cc homozygous recessive alleles. As per punnett square method the offspring cocoon color will follow the above mentioned genotypic and phenotypic ratios respectively.
