Chesapeake Bay is an inland estuary that is home to a species of oyster called Crassostrea virginica. These oysters begin their lives as free-swimming larvae. Before they can become adult osyters, the larvae must attach to a hard surface. Over the last 100 years, oyster harvesting in Chesapeake Bay has slowly reduced the size of the oyster beds that larvae use for attachment. Based on the information above, which statement best describes how harvesting has affected Crassostrea virginica?
A.
Populations have most likely declined due to decreased food availability.
B.
Populations have most likely grown due to an increase in available space.
C.
Populations have most likely grown due to decreased competition with other organisms.
D.
Populations have most likely declined due to a decrease in reproduction rates.

One significant difference between an ionic bond, where electrons are taken from one atom and added to another atom, and a covalent or metallic bond, where electrons are shared is

State the formula for density in words and mathematical symbols

Since the gas in your graduated cylinder is a mixture of butane and water vapor, you must determine the partial pressure of the butane, pbutane, alone. to do this, consult a reference and record the partial pressure of the water vapor, pwater, at the temperature you recorded. use the following formula to compute the partial pressure of the butane. pbutane = atmosphere - pwater use the following combined gas law formula and compute the volume that the butane sample will occupy at stp. (hint: convert both temperatures to kelvin.) pbutane x voriginal = pstandard x vfinal troom tstandard use the following ratio and proportion formula to determine the mass of butane needed to occupy a volume of 22.4 l at stp. grams of butane you used “x” grams of butane ml of butane corrected to stp = 22,400 ml compute the theoretical molar mass of butane based on its formula and the atomic masses on the periodic table. compare your experimental results from #3 to the theoretical value of #4, computing a percent error of your findings using this formula: % error = measured value - accepted value x 100 accepted value use the following ratio and proportion formula to determine the mass of butane needed to occupy a volume of 22.4 l at stp. need asap
