Because of high increases in populations, some underdeveloped countries are already exceeding their carrying capacity. They cannot produce enough food to support their populations. These regions are undergoing very rapid desert formation. Growing populations contribute to this by clearing forests for agriculture and firewood. Which region in the table is most likely experiencing desert formation? Explain. Hint: Think about where the population is increasing the most quickly.

Based on the evidence in the excerpt above, describe in your own words what it would have been like for a person to enter a meat processing plant in the united states

Which image shows labeled organelles that are present only in plant cells?

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.
