15. Cells found in plants and animals have similarities but can differ in function. Consider the
following two organisms: a corn plant cell (Zea mays) and a camel cell (Bactrianus ferus). What is the
best explanation for the difference in the cellular vacuole size between these two biotic
organisms?
A. The corn cells' have a small vacuole size because it does not need long term water and electrolyte
storage.
B. The camel cells' have a small vacuole size because it does not need long term water and
electrolyte storage.
C. The camel cells' have a small vacuole size because it is not in contact with toxins that need to be
removed from the cell.
D. The corn cells' have a large vacuole size because it is in contact with many toxins in the soil which
need to be removed from the cell.

Which equation is used to calculate the magnetic force on a charge moving in a magnetic field

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)

Why was mendel's work not accepted at the time? o a. his results were false. o b. he did not repeat his experiments. o c. he did not have any data. o d. his results were surprising,
