Which experiment would BEST investigate the effect temperature has on the volume of a gas? A.
Inflate one balloon to a large volume and another balloon to a small volume. Measure the temperature of the air released from both balloons.

B.
Stretch a balloon over the top of a beaker filled with baking soda and vinegar, then observe how the balloon changes volume as the reaction occurs.

C.
Measure the volume of a balloon filled with room temperature air; place the balloon in a freezer for an hour and measure its volume again.

D.
Measure the pressure of the air in a bicycle tire on a cold day.

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.

Acell in the human nervous system whose primary function is to form myelin and the blood-brain barrier, respond to injury, remove debris, and enhance learning and memory is called a(n) cell.
