Answer: The correct answer is-
B. Yy
As per the information in the question, yellow (depicted by Y allele) seed color is a dominant trait whereas green seed color is a recessive trait ( depicted by y allele).
A dominant trait always masks the expression of a recessive trait.
Presence of single dominant allele ( such as in Yy, which shows heterozygous dominant genotype) in the genotype can produce a dominant trait whereas recessive trait is only expressed when its genotype is homozygous recessive (such as yy that is both alleles should be recessive allele) .
A plant with genotype Yy will form two gametes that is Y and y.
When such plants are allowed to interbreed, there is a probability of 25% of producing green seeds in the next generation.

Answer:
The correct option is: a. glycogen, starch, and amylopectin
Explanation:
Glycogen, amylopectin and starch are the polysaccharides of glucose. These polymers are composed of monomeric α-glucose units, which are joined by α(1→4) glycosidic bonds.
Since, the amylase enzyme can act only on the glycosidic bonds formed between α-glucose monomers. Therefore, amylase can break down glycogen, starch, and amylopectin.
Answer:
D. service
Explanation:
Most people in the US work in jobs that require providing a service to others, whether it's at a restaurant, a department store, a school, etc. Yet, those who work in specialised jobs like agriculture, fishing, and mining are more rare because they need to live in a certain area that is optimal for such positions.
Thus, the answer is D.
