An unusual red sponge is discovered near a deep-sea vent. You want to determine if this is a new species of sponge, so you separate the cells for further study. A new lab assistant accidentally adds cells from a blue sponge to your preparation while you are at lunch. When you return, you find that the sponge cells have reaggregated into a multicellular organism. What do you see if the red and blue sponges are the same species?

A. one sponge with blue and red randomly distributed
B. one blue sponge and one red sponge
C. one purple sponge (mix of red and blue colors)
D. one sponge with a red side and a blue side
E. one sponge with alternating red and blue layers of cells

Some organisms exhibit flexibility in terms of their energy harvesting reactions. If provided with oxygen, they will obtain energy through aerobic respiration. If in an environment without oxygen, they will turn to fermentation to satisfy their energy needs. These organisms are classified as:

obligate aerobes obligate anaerobes microaerophiles facultative aerobes aerotolerant anaerobes
