A college student has been assigned to write captions for a new textbook on gravity and motion. This is one of the pictures from the textbook. Earth, the moon, and the orbit of the moon around Earth. The moon has one arrow pointing toward Earth, and one pointing down away from Earth.

Which caption best describes the thinner arrow?

The moon moves toward the Sun due to gravity.
The moon will move away from Earth because of inertia.
The moon would move in a circular path if there were no forces.
The moon would not stay in orbit without the pull of Earth's gravity.

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. (2 points)
