The scientists need a material that is a superconductor at temperatures greater than 273 k. which of the following would be best for the scientists to do next?

a.) they should repeat the experiment with a material that is known to be a superconductor only at temperatures below 4 k.
b.) they should repeat the experiment with a modified form of material b.
c.) they should repeat the experiment using the same materials at a higher temperature.
d.) they should repeat the experiment with the same substances to try to obtain different results.

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.
