Select the correct text in the passage. Pick the correct sentences that correctly describe environmental factors that affect seagrass.

1. Seagrass meadows face threats from large animals that may uproot plants (correct)
2. Algal blooms are also harmful as the block available sunlight
3. Fertilizer runoff, however, causes seagrass populations to grow rapidly (incorrect)
4. Seagrass meadows are also impervious to strong currents and storms
5. Removal of predators can cause herbivores to over feed on seagrass
6. Wage ads can thrive in water of any temperature and are not affected by temperature changes

(I took the test and put 1 and 3 and got it partially correct)

Match the types of competition to their descriptions.

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.
