In most stable freshwater environments, populations of daphnia are almost entirely female and reproduce asexually. however, males are observed in low oxygen environments or when food is scarce. based on these observations, a researcher suggests that male daphnia develop in response to unfavorable environmental conditions. this is an example of a:

The lake of the ozarks is a human-made lake, so it collects runoff from coal strip-mining, fertilizers, resort wastewaters, and septic drainages. the average lake temperature is between 10∘c and 21∘c. consider the physical requirements for growth and multiplication that would allow fecal coliforms to “blossom” in the lake of the ozarks. which of the following would accurately describe these organisms? check all that apply. psychrophiles facultative halophiles extremophiles mesophiles hyperthermophiles
