Crassostrea virginica, a species of oyster, is a keystone species that lives in the Chesapeake Bay, which is on the northeast coast of
the United States. These oysters build reefs that provide a habitat to numerous species of aquatic life and help to stabilize the
coastline. In addition, these oysters filter the water around the reefs.
Based on this information, which of the following best describes how removing a keystone species like Crassostrea virginica from
an ecosystem compares to removing a species that is not a keystone species?
A. Removing a keystone species is likely to cause a less significant change in the ecosystem.
B. Removing any species, whether or not it is a keystone species, is not likely to cause a change in the ecosystem.
C. Removing any species, whether or not it is a keystone species, is likely to cause the same degree of change in the
ecosystem
D
Removing a keystone species is likely to cause a more drastic change in the ecosystem

Zoe decided to measure the hand length of each of her classmates. first she marked a line across each student's wrist and lined up a ruler from this mark to the top of the middle finger to measure the length. then she recorded the measurements in the table below. marla did this the same way for each classmate, and then zoe used this ruler to measure each straight line and record the data below. this data is invalid. what is the most likely reason why it is invalid? the ruler is marked in centimeters, but zoe recorded data in inches. the range of lengths is too wide, so zoe must have misread the ruler. marlaโs complicated measuring procedure was overly confusing. marla could have been inconsistent while drawing outlines of fingers.
