Answer:
Explanation:
Staining is done for onion cells to visualize the cytoplasm of yellow and white onions because they are not pigmented. The staining of human cheek cells with methylene blue is necessary to stain the nucleus to get clear image of it under microscope because methylene blue binds to negative charge nucleic acids
While for leaf epidermal cells smears, staining is not necessary as they are visible under light microscope without staining and they also have pigmented materials inside them such as chlorophyll chloroplast. The cork cell is a non-living and have a cell wall whose structure is visible under light microscope.
Gametes have 23 chromosomes, while other normal human cells have 46 chromosomes.

What is chromosome?</h3>

Answer: Growth refers to an increase in physical size of whole or any of its part and can be measured. Development refers to the qualitative changes in the organism as whole. Development is a continuous process through which physical, emotional and intellectual changes occur.
Answer:
d. incomplete dominance
Explanation:
When none of the alleles of a particular locus completely masks the expression of the other allele of the same gene, it is called incomplete dominance. If the allele B gives "blue" phenotype and allele b gives white phenotype, a cross between blue (BB) and white (bb) parents would produce all the progeny with genotype Bb. Since the allele B does not completely prevent the expression of allele b in the heterozygous condition, the phenotype of the F1 hybrids would be "light blue". Therefore, it is an example of incomplete dominance.
blue (BB) x blue (BB) = all blue (BB)
white (bb) x white (bb)= all white (bb)
blue (BB) x white (bb)= all light blue (Bb)
