James wants to create a self-sustaining ecosystem, or vivarium. which method would most likely result in an ecosystem that is viable for the longest amount of time with no additional care? put a few plants, water, sand, and a heat lamp inside a clear glass aquarium and seal the top. place it in a sunny location. put water, fertilizer, soil, plants and insects in an open, clear glass aquarium. place it in an area that has some sunlight and some shade. put rocks, water, and many plants in an open, dark-colored plastic tub. place it in an area with direct sunlight. put soil, water, many plants, and a few insects in a sealed, clear plastic aquarium. place it in an area with indirect sunlight.

The dna in a cell’s nucleus encodes proteins that are eventually targeted to every membrane and compartment in the cell, as well as proteins that are targeted for secretion from the cell. for example, consider these two proteins: phosphofructokinase (pfk) is an enzyme that functions in the cytoplasm during glycolysis. insulin, a protein that regulates blood sugar levels, is secreted from specialized pancreatic cells. assume that you can track the cellular locations of these two proteins from the time that translation is complete until the proteins reach their final destinations.for each protein, identify its targeting pathway: the sequence of cellular locations in which the protein is found from when translation is complete until it reaches its final (functional) destination. (note that if an organelle is listed in a pathway, the location implied is inside the organelle, not in the membrane that surrounds the organelle.)

According to the rna world hypothesis, rna acted as the genetic material and catalyzed reactions in ancient cells. what conclusion can you draw from this?               a.  this implies that dna and proteins aren't essential in cells today.    b.  this implies that rna can catalyze any chemical reaction that enzymes catalyze.    c.  this implies that if a cell has a problem with its dna, its rna can compensate for the damaged dna.    d.  this implies that dna and proteins evolved after rna.
