A student designed an experiment to demonstrate the interaction between Earth systems. The steps of the experiment are given below. Fill three-fourths of a glass jar with water. Add a teaspoon of liquid dish soap and a teaspoon of vinegar to water. Tighten the lid and shake the jar to mix the ingredients. Swirl the jar in a circular motion and watch the spinning motion of the liquid inside. The student’s experiment demonstrates the formation of:
A. blizzard due to the interactions between the hydrosphere and geosphere
B. hurricanes due to the interactions between the geosphere and atmosphere
C. tornadoes due to the interactions between the hydrosphere and atmosphere
D. thunderstorms due to the interactions between the hydrosphere and cryosphere

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.

Which best example best demonstrates the importance of having knowledge of evolutionary relationships? a. illustration of a plant b. organ transplantation between species c. blood donation from a human d. do you need sequence of an insect.

Forensic scientists think they know the identity of a skeleton. what rule should they use to select a relative whose dna could be used to try to confirm the identity?
