Why is vegetation on the eastern slopes of the Cascades different from the west?
The eastern slopes of the Cascades receive significantly
less annual precipitation. Vegetation is modified because
of the reduced rainfall and snowfall. The primary forested
areas are populated by dense lands of Engelmann spruce,
grand fir, silver fir, and Douglas fir conifers. Streambeds
and lower elevated areas are perfect for mixed deciduous
varieties of vine maple, alder, larch, oak, and aspen trees.
Open areas include meadows, steppe grasslands, and
dense bushes and thickets. The animal life is similar to
the western Cascades. Perhaps the biggest difference is
the existence of venomous rattlesnakes.
O The climate is too cold in that area of the region.
Less precipitation falls on the east side of the
mountains than the west.
O That side of the mountains is too snowy for plants
to grow.
O The soil in that area does not support the growth of
trees.

The diagram below represents a marine food web and a process that can harm the human population. each circle represents an organism and the smaller dots inside them represent a toxic substance. what is being represented and how does it harm the population? the diagram represents biological half-life, in which toxins build up in organisms higher up on the food chain, and this can negatively impact humans who consume the organisms and the toxic substance. the diagram represents biomagnification, in which toxins build up in organisms higher up on the food chain, and this can negatively impact humans who consume the organisms and the toxic substance. the diagram represents the process by which different organisms prey upon each other; this can impact the human population by reducing the number of organisms that do not contain the toxin. the diagram represents the way that toxins are metabolized by living organisms, with those at greater trophic levels able to metabolize more efficiently than those at lower levels. this means that those at higher tropic levels are safer for humans to consume compared to the organisms at lower trophic levels.

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.
