Every person has responsibilities having to do with his or her private life. People have to help take care of themselves and their families. They fulfill these responsibilities in many ways. Americans also have civic responsibilities. These are the things people must do in order to help support their community and their government. Our system of government depends on the active involvement and participation of people in a number of tasks. For example, because ours is a government of, for, and by the people, citizens must run for office, and others must participate in elections. Where both of these types of responsibilities meet, a better community can be formed. Some examples of both types of responsibilities working for society is: speaking out on beliefs, cooperating with others, seeking compromise in conflict, and volunteering time and resources towards our community. All of these things will bring about a positive change in society.

Considering the yellow and green pea color phenotypes studied by gregor mendel: a. what is the biochemical function of the protein that is specified by the gene responsible for the pea color phenotype? (1 point) b. a null allele of a gene is an allele that does not specify (or encode) any of the biochemical function that the gene normally provides (in other words, either no protein at all or only non-functional protein is produced from it). of the two alleles, y and y, which is more likely to be a null allele? (1 point) c. in terms of the underlying biochemistry, why is the y allele dominant to the y allele? (2 points) d. why are peas that are yy homozygotes green? (1 point) e. the amount of protein produced from a gene is roughly proportional to the number of functional copies of the gene carried by a cell or individual. what do the phenotypes of yy homozygotes, yy heterozygotes, and yy homozygotes tell us about the amount of sgr enzyme needed to produce a yellow color? explain your reasoning.
