True or false

1. the populations of many fishes have decreased because the fishing industry has become highly mechanized.

2. the goal of maximum sustainable yield management is to harvest resources in ways that minimize impact on the ecosystems and ecological processes that provide the resource.

3. timber harvesting always results in the destruction of the forest.

4. timber is harvested from national forests by government resource managers.

5. wildfire suppression prevents future fires by reducing the amount of forest debris on the forest floor.

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.
