A gardener is installing several large flower beds. The flower beds will vary in length from 5 to 12 feet. Depending on the type of flower, the flowers are to be planted 3 to 12 inches apart. The gardener will measure the outlines of all the flower beds first. Then, she must plant each flower one by one, measuring the spacing of each flower relative to adjacent flowers in all directions. How should the gardener approach the measurements she needs to make? A. She should use a tape measure to measure both the flower spacing and the flower beds. B. She should use a ruler to measure the flower spacing and use a tape measure with multiple feet to measure the flower beds. C. She should use a tape measure with multiple feet to measure the flower spacing and use a ruler to measure the flower beds. D. She should use a ruler to measure both the flower spacing and the flower beds.

If the birth rate of a population of dolphins is 2.0, the death rate is 0.5, and the population size is 100, what is this dolphin's population growth?

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.
