Many organisms in the deep sea live in conditions where resources are rare and populations are small and sparse. many of those species are also hermaphroditic. which of these is a plausible explanation for high rates of hermaphroditic species there?
a. reproductive assurance: any individual of the same species is a potential mate
b. excess energy: excess resources can be allocated to the other sex function
c. size advantage: males are more successful when large, but female fitness does not change with size
d. small body size: one sex or the other needs only a miniscule body size for full function
e. inbreeding: populations are inbred and hermaphroditism is a side effect

After reading the paragraph below, answer the questions that follow. researchers have created a robot that has a very thin leg that is moved by cardiac (heart) cells contracting in unison. the robot, made of a polymer similar to that used in making contact lenses, is bathed in heart cells with supporting cells, which then attach to the robot and provide movement as they contract. all of the cardiac cells working together can cause the robot leg to move in a way that individual cells could not. this is an example of a. emergent properties of cells. b. energy flow through an ecosystem. c. adaptation. d. internal environment regulation.

Which best explains how a heat pump can heat a room? cold air from the house is moved through pipes, where it absorbs thermal energy. warm air from outside is pushed into the house to replace the cold air. combustion warms the air when chemical energy is transferred to thermal energy. fuel is used to move a piston, which pushes warm air into the house.
